Tue, 30 Nov 2010 11:01:12 EST Article 299 at www.pavementpreservation.org Long-time pavement preservation researcher and Pavement Preservation Expert Task Group associate Larry Scofield, P.E., was honored with the 2008 Lester F. Kuzmick Award, the highest honor bestowed by the International Grooving & Grinding Association. Scofield is director of environmental engineering for the American Concrete Pavement Association, which he joined in 2005. An authority on sound generated at the tire/pavement interface, previously he spent nearly 30 years with the Arizona DOT, most recently as pavement management engineer. Tue, 30 Nov 2010 10:59:27 EST Article 298 at www.pavementpreservation.org The Texas Pavement Preservation Center (TPPC) recently conducted a significant amount of research into the use of reclaimed materials in pavement preservation. One important study conducted by the TPPC in this area has examined the feasibility and future benefits of utilizing waste toner in hot-mix asphalt overlays. Tue, 30 Nov 2010 10:57:55 EST Article 297 at www.pavementpreservation.org A new association promoting the preservation of bridges of all types was founded in late 2008, and was publicly launched during the Transportation Research Board meeting in Washington, D.C., in mid-January 2009. The new group follows a path blazed by the January 2008 Transportation System Preservation Research and Implementation Road Map, and the Foundation for Pavement Preservation, which was founded in 1992. Tue, 30 Nov 2010 10:56:29 EST Article 296 at www.pavementpreservation.org Over 90 abstracts were received by the submittal deadline for presentations at the First International Conference on Pavement Preservation, April 12-16, 2010, in Newport Beach, Calif. The main theme of the conference will be pavement preservation and sustainability, and the conference will address an array of issues that are relevant to the pavement preservation community. Tue, 30 Nov 2010 10:55:13 EST Article 295 at www.pavementpreservation.org The Transportation System Preservation Technical Services Program (TSP•2) of the American Association of State Highway & Transportation Officials (AASHTO) continues to grow in popularity with transportation practitioners as it completes its third year of operation. Established in 2006 and managed by the National Center for Pavement Preservation (NCPP), the program was created to serve as a clearinghouse for transportation system preservation technical expertise, and to provide a forum for information exchange among system preservation practitioners. Tue, 30 Nov 2010 10:53:56 EST Article 294 at www.pavementpreservation.org A team of researchers centered around the Highway Sustainability Research Center of the University of Massachusetts-Dartmouth has begun field surveys of thin-lift asphalt overlays containing higher levels of reclaimed asphalt pavement (RAP) and Sasobit® additive for warm mix asphalt. Research team members include Walaa S. Mogawer, Ph.D., P.E., professor, Civil & Environmental Engineering, and director, Highway Sustainability Research Center, UMass-Dartmouth; Alexander J. Austerman, M.Sc., research engineer, Highway Sustainability Research Center; Bryan Engstrom, grad student, UMass Dartmouth; and Ramon Bonaquist, P.E., chief operating officer, Advanced Asphalt Technologies, LLC. Tue, 30 Nov 2010 10:51:57 EST Article 293 at www.pavementpreservation.org Caltrans — the California Department of Transportation — is planning to start an ambitious in-place recycling initiative over the next three years, and has been examining different in-place recycling techniques to test their applicability to the Golden State. Via in-place recycling, the state hopes to reap savings in materials, labor and energy costs, as well as lower emissions and reduce the carbon footprint associated with conventional pavement overlays. In advance of the initiative, Caltrans placed in-place recycling projects, which included full-depth reclamation (FDR), hot in-place recycling (HIR), and cold in-place recycling (CIR) projects in various locations. Tue, 30 Nov 2010 10:50:28 EST Article 292 at www.pavementpreservation.org The push to recycle and conserve is in our collective best interest as nations, businesses and individuals. Pavement preservation is, by its very nature, a conservation practice, and when we can utilize 100 percent reclaimed asphalt pavement (RAP) in slurry seals, pavement preservation’s contribution to saving resources is greatly enhanced. RAP slurry seals eliminate the need for additional virgin aggregate mining, as well as reduce pressure on crude oil demand, as the requirement for asphalt emulsion is reduced by 20 percent compared to typical emulsion aggregate slurry seals. Tue, 30 Nov 2010 10:47:18 EST Article 291 at www.pavementpreservation.org The Asphalt Emulsion Manufacturers Association (AEMA) exists to promote the increase — and more efficient use — of asphalt emulsions. AEMA is a proactive organization dedicated to the advancement of the asphalt emulsion industry, constantly focusing on system preservation and the construction of the world’s infrastructure. Tue, 30 Nov 2010 10:42:30 EST Article 288 at www.pavementpreservation.org This project’s purpose was to compare emulsion chip seal binder to hot asphalt cement binder based on actual project performance. A comparative analysis of the binders was completed over a three-year period on 10 rural roads that received new chip seals in the Texas Department of Transportation’s (TxDOT) San Antonio District 2005 chip seal program. Tue, 30 Nov 2010 10:41:03 EST Article 287 at www.pavementpreservation.org One of the strategies available for pavement preservation is cold in-place recycling (CIR), which uses asphalt emulsion as a main component. Unlike asphalt binders, for which performance-based specifications are readily available, asphalt emulsions lack a similar set of testing procedures. This research effort explored the existing methods used to characterize asphalt emulsions and identified potential test methods for characterizing asphalt emulsions in terms of their field performance. The main objectives of this project were to better understand the role of asphalt emulsions in recycled asphalt pavements and to develop the means to better characterize their properties related to their field performance. Tue, 30 Nov 2010 10:39:41 EST Article 286 at www.pavementpreservation.org Transverse variance of asphalt rates (TVAR) is the seal coat practice of varying the amount of seal coat asphalt across the width of the roadway, in order to better address the needs of the existing pavement surface. TVAR allows more asphalt to be put on the road without causing flushing in the wheel paths, resulting in a better seal overall. This practice can be used to improve the skid properties of the roadway by reducing wheel path flushing, while at the same time providing adequate asphalt coverage outside of the wheel paths to securely hold aggregate. Tue, 30 Nov 2010 10:38:11 EST Article 285 at www.pavementpreservation.org Fog seals are emulsions consisting of asphalt, water and surfactant. Rejuvenator seals are emulsions consisting of petroleum rejuvenating base oils (maltenes, saturates, acidiffins). Some contain additional asphalt. Both fog and rejuvenating seals are spray applied to an existing asphalt concrete (AC) pavement surface. Fog and rejuvenating surface seals have been used by agencies over the last several decades. Tue, 30 Nov 2010 10:32:10 EST Article 284 at www.pavementpreservation.org Most highway agencies across the country are facing significant challenges as a result of stagnant or declining revenue streams, driven by a sagging economy and increasing numbers of fuel efficient or alternatively fueled vehicles on the road. At the same time they are also confronted with a growing backlog of highway infrastructure maintenance and renewal needs. While highway agencies are increasingly turning to pavement preservation strategies to cost-effectively address their pavement needs, elimination or deferral of training are often early casualties of cost-cutting efforts when revenues decline as quickly and dramatically as they have in the past year. Tue, 30 Nov 2010 10:30:51 EST Article 283 at www.pavementpreservation.org More than 20 state and county personnel journeyed to Rockport, Ind., to see if micro surfacing of an Indiana highway might demonstrate cost-effective alternative for their agencies. The project location was S.R. 70 between U.S. 231 and S.R. 66 outside of Rockport. The pavement exhibited minor rutting and concomitant deterioration of asphalt. The Indiana Department of Transportation specified micro surfacing on an 8.5-mile stretch of the two-lane state road. Tue, 30 Nov 2010 10:28:28 EST Article 282 at www.pavementpreservation.org An Alabama contractor introduced a rapid setting asphalt emulsion for a Cherokee County, Ala., pavement preservation treatment that saved time between applications and expedited the return of traffic to the county road. Gadsden, Ala., paving specialist Charles E. Watts, Inc., received permission from the county highway department to use CHFRS-2P, a cationic, high-fl oat rapid-setting emulsion modified with latex, on its contract to double chip seal a section of County Route 29. This was the first-time use of the product in an Alabama county. Tue, 30 Nov 2010 10:27:11 EST Article 281 at www.pavementpreservation.org Fewer broken windshields and higher early chip retention for chip seal coats. Longer lasting pavement preservation surface treatments. Return to full traffic speed in less than an hour. Lower cost surfaces for very high traffic volume roads. They’re all among the attributes of polymer modified asphalt emulsions. Experience has led maintenance and preservation engineers to believe that polymer modified asphalt emulsions give better short- and long-term performance than conventional emulsions. Tue, 30 Nov 2010 10:25:55 EST Article 280 at www.pavementpreservation.org We know that pavement preservation practices conserve scarce pavement maintenance dollars both now and in the future. But earlier this year we learned more detail about the actual costs of driving on roads needing maintenance, and the details don’t refer to how much money an agency might save; instead they look at costs incurred by road users themselves. Driving on rough roads costs the average American motorist approximately $400 a year in extra vehicle operating costs, reported the American Association of State Highway & Transportation Officials (AASHTO), and The Road Information Program (TRIP), an industry nonprofit organization that promotes transportation policies that relieve traffic congestion, improve road and bridge conditions, improve air quality, make highway travel safer and enhance economic productivity. Tue, 30 Nov 2010 10:24:36 EST Article 279 at www.pavementpreservation.org The highway infrastructure component of the American Recovery and Reinvestment Act of 2009 (ARRA) presents all states with a choice of funding capital projects, or pavement preservation. Thus many state DOT members of the Northeast Pavement Preservation Partnership (NEPPP) have benefited by being able to steer some of these funds toward pavement preservation projects. Both agency-specific and external forces are likely to influence the project selection process for ARRA funding, yet pavement preservation presents several benefits regardless of the situation and decision process. Tue, 30 Nov 2010 10:23:26 EST Article 278 at www.pavementpreservation.org Big changes are occurring at the Foundation for Pavement Preservation (FP2). As a result of a strategic planning session held in Atlanta in October 2008, and several planning task force meetings that followed in January and March 2009, FP2 has established new goals for the future of pavement preservation. Tue, 30 Nov 2010 10:22:11 EST Article 277 at www.pavementpreservation.org Asset Management of civil infrastructure facilities and systems is gaining importance both in practice and academia as the public demands increased accountability in government, laws are passed requiring infrastructure asset management use, and growth and development accelerate the deterioration of already aged infrastructure. In response, more agencies adopt and develop their asset management practices and more academic institutions and continuing education programs develop courses and programs in civil infrastructure asset management. Tue, 30 Nov 2010 10:06:52 EST Article 276 at www.pavementpreservation.org As an advocate for better, safer and environmentally friendly roads, the International Road Federation (IRF) brought together public and private sector experts from around the world to examine current practices and discuss new strategies for pavement preservation in a recent seminar, Preserving our Highway Infrastructure Assets. The seminar addressed such key issues as the role of new materials and technologies for pavement preservation, new funding strategies and contracting models to sustain pavement preservation, and the latest tools for the management of pavement networks. Tue, 30 Nov 2010 10:05:10 EST Article 275 at www.pavementpreservation.org In these economically challenging times, pavement specialists must get back to the fundamentals — correcting small defects before they become embarrassingly large ones, and making sure we use the right treatment at the right time to extend the life of our pavements. Because of the need to get back to the sound fundamentals of maintenance, The Asphalt Institute has just finished updating one of its most widely used technical manuals, MS-16, Asphalt in Pavement Preservation and Maintenance, 4th Edition. This new edition has been updated to include a brief overview of all of the principles of pavement management and preservation and descriptions of all of the recognized repair techniques and surface treatments. Tue, 30 Nov 2010 10:03:57 EST Article 274 at www.pavementpreservation.org The county of Santa Barbara has developed and maintained an award-winning nationally recognized pavement preservation program that is extending the life of its pavement network through the use of pavement preservation practices, including fiscal tracking and condition surveys using asset management software. These practices have been integrated into the county public works planning to provide powerful tools for budgeting in the face of increasingly limited funding. Tue, 30 Nov 2010 10:02:30 EST Article 273 at www.pavementpreservation.org Valued at more than $40 billion, the 40,000 miles of the San Francisco Bay Area’s local streets and roads serve as the foundation of the region’s transportation infrastructure. The local street and road network is essential to the transportation efficiency, safety, and the social and economic health of the region. As such, properly investing in and managing this asset is essential for the long-term health of the San Francisco Bay Area’s transportation system. The Metropolitan Transportation Commission (MTC) is the regional planning, programming and finance agency for the nine-county San Francisco Bay Area. Tue, 30 Nov 2010 10:01:01 EST Article 272 at www.pavementpreservation.org “They paint the roads black just before an election.” “They schedule road work according to the number of complaints or squeaky wheels.” “The councilman gets his road resurfaced first.” We have all heard these comments before, and depending on where you reside in the nation, they may or may not be true. The City of Los Angeles, however, has a very different strategy. The city knows that investing in pavement preservation reduces the four-to-five times higher cost of rehabilitation. Furthermore, the city’s street managers want residents, stakeholders, and the general public to fully comprehend the simple concept of “pay less now, or pay much more later.” Tue, 30 Nov 2010 09:59:44 EST Article 271 at www.pavementpreservation.org Adding pavement preservation (PP) components to a pavement management system (PMS) can benefit both PMS and the pavement preservation program. The potential benefits of a successful pavement preservation program are numerous, including higher customer satisfaction, increased safety, increases in cost savings and cost effectiveness, improved pavement condition, improved strategies and techniques and better-informed decisions. A pavement preservation program should be included in an agency’s pavement management system. Tue, 30 Nov 2010 09:58:10 EST Article 270 at www.pavementpreservation.org Jim Sorenson, senior construction and system preservation engineer, Office of Asset Management, Federal Highway Administration — and a great champion of pavement preservation at the national level — died suddenly Saturday, June 27, at the age of 59. The pavement preservation industry had no greater friend and it is with deep sadness that the Foundation for Pavement Preservation notes his passing. Tue, 30 Nov 2010 09:56:34 EST Article 269 at www.pavementpreservation.org Here’s a glossary of pavement coating terminology, adapted from FP2, Inc. Wed, 24 Nov 2010 11:43:07 EST Article 250 at www.pavementpreservation.org Last week, while we were twiddling our thumbs and waiting for something to revelate, we received this e-mail from Larry Nieder. Fri, 19 Nov 2010 11:56:32 EST Article 242 at www.pavementpreservation.org Author: Arudi Rajagopal, Ph.D. Publication Date: 05/2010 Abstract / Description: Chip Seal and Micro Surfacing are important components of ODOT’s pavement preventive maintenance program. Thorough understanding of how well these treatments are performing is critical to the nature and extent of their continued use in the future. Currently, there is a lack of objective information on fundamental issues such as the expected improvement in pavement condition resulting from the use of chip seal and micro surfacing, the extent to which the treatments slow the deterioration of the pavement, and the optimum timing of the treatment. As a result, present guidelines are based on anecdotal observations and experience. This study was initiated to systematically evaluate and quantify the performance and cost-effectiveness of ODOT’s current chip sealing and microsurfacing practices using the data from completed and in-service projects. Thu, 18 Nov 2010 14:19:53 EST Article 241 at www.pavementpreservation.org "An independent standards development organization has verified the findings of an eco-efficiency analysis (EEA) of asphalt pavement technologies which shows micro-surfacing using a styrene-butadiene-rubber (SBR) latex polymer to be more economical, and to cause less environmental impact, than "mill and fill" utilizing hot mix asphalt" -- Pavement Preservation Journal, Winter 2010.

Mon, 15 Nov 2010 09:18:14 EST Article 222 at www.pavementpreservation.org Background: Bridge scour, the erosion of stream material around the bridge foundation, is responsible for many of the bridge failures in the United States. Local bridge scour is caused by the interference of bridge piers with the flow of water and is characterized by the formation of scour holes. Local scour occurs at a bridge pier when the local flow field is strong enough to remove bed materials. Several variables affect the scour depth including the flow intensity, the relative flow depth, the pier-width, and the properties of the river bed materials.
