Book Pavement Maintenance Effectiveness

Download or read book Pavement Maintenance Effectiveness written by Roger Smith and published by Strategic Highway Research Program (Shrp). This book was released on 1993 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated 6 specific preventive treatments. Four treatments are for asphalt concrete surfaced (flexible) pavements: chip seals; crack sealing; slurry seals; and thin overlays. Two treatments are for portland cement concrete surfaced pavements: joint and crack sealing; and undersealing. Performance of the pavement sections with the treatments was compared with the performance of a similar pavement section without the treatment. Performance is measured in terms of pavement distress, roughness profile, surface friction, and structural capacity. All of the flexible pavement test sections and most of the rigid pavement test sections have been constructed. Performance data are being collected. This report discusses the experimental design, project selection, construction, data collection, analysis, and future activities of the pavement maintenance effectiveness project.

Book LTPP Pavement Maintenance Materials

Download or read book LTPP Pavement Maintenance Materials written by and published by . This book was released on 1999 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Strategic Highway Research Program (SHRP) H-106 maintenance experiment and the Federal Highway Administration (FHWA) Long-Term Monitoring (LTM) of Pavement Maintenance Materials Test Sites project studied the resealing of joints in concrete pavements. The purpose of joint resealing is to reduce the amount of water entering a pavement structure and to prevent the filling of joints with incompressible materials. Although joint resealing is a common maintenance practice, premature seal failure is frequent, leading to additional repair and expenditures. The purpose of this study, then, was to address the merits and deficiencies of current joint resealing materials, designs, and practices. The study evaluated the relative performance of selected sealant materials, as well as the effect of selected sealant instalfation methods. The study also identified sealant inaterial properties and tests that correlate well with field performance. The effect of joint seal performance on pavement life was not addressed in this study. This report documents the entire PCC joint resealing study, including the installation of 31 unique joint seal treatments (i.e., combinations of sealant material and installation method) at 5 different test sites, the laboratory testing of experimental sealant materials, and the 7-year performance monitoring of the various joint seal treatments. It also discusses the redts of comprehensive statistical analyses conducted on material performance and laboratory testing data. The results of a detailed cost-effectiveness analysis are also presented"--Tech. report doc. pg

Book Concrete Pavement Preservation Workshop

Download or read book Concrete Pavement Preservation Workshop written by Kurt D. Smith and published by . This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document serves as the Reference Manual for the 1 1/2 -day FHWA workshop on concrete pavement preservation. The purpose of the document is to provide the most up-to-date information available on the design, construction, and selection of cost-effective concrete pavement preservation strategies. It concentrates primarily on strategies and methods that are applicable at the project level, and not at the network level, where pavement management activities function and address such issues as prioritizing and budgeting. Detailed information is presented on seven specific concrete pavement preservation treatments: slab stabilization, partial-depth repairs, full-depth repairs, retrofitted edge drains, load transfer restoration, diamond grinding, and joint resealing. In addition, information is provided on pavement evaluation techniques and strategy selection procedures.

Book Optimizing Maintenance Activities

Download or read book Optimizing Maintenance Activities written by Delmo E. Koop and published by . This book was released on 1980 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study was conducted by Iowa, Kansas, Nebraska, and South Dakota. The joint repair problems of each State are characterized by complex, individualistic requirements, where only varying degrees of adaption between the repair methods of the different States are feasible. The magnitude of the problems require efforts toward increasing production in both contract and maintenance repair operations. Maximizing the use of machinery to accomplish the work in place of labor-oriented procedures is emphasized. Two States with similar situations found that a savings of approximately 16.00 dollars per square yard was realized for full-depth repairs by modifying their current procedures.

Book Effectiveness of Existing Rehabilitation Techniques for Jointed Concrete Pavements

Download or read book Effectiveness of Existing Rehabilitation Techniques for Jointed Concrete Pavements written by and published by . This book was released on 1986 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information was collected from each of the six states in Region 5 of the Federal Highway Administration (FHWA) on the procedures used to rehabilitate jointed concrete pavements. As built plans and specifications were obtained from a number of projects in each of the six states which had been rehabilitated and the performance of the pavements were studied after a number of years in service. Interviews were conducted with personnel of the Departments of Transportation from each state to collect as much information as possible concerning the current practices and techniques used for pavement rehabilitation. Where sufficient data were available, statistical correlations were made of the performance trends as they relate to specific rehabilitation practices. Current practices were compared with earlier practices and efforts made to determine the reasons for the changes. Results show that the performance is closely related to the workmanship in the field and the ingenuity of the engineers involved. Recommendations are presented for each of the rehabilitation techniques studied. Many problems still exist with all of the techniques studied. Further detailed data on the exact procedures and practices used in the field during the rehabilitation and performance after rehabilitation are desperately needed. Better record keeping is sorely needed on both the "as built" conditions and on the performance, so the effectiveness of the various practices can be documented.
