Book Synopsis Characterization of Low Temperature Cracking Potential for Westrack Paving Materials by : Thomas Walker
Download or read book Characterization of Low Temperature Cracking Potential for Westrack Paving Materials written by Thomas Walker and published by . This book was released on 1999-01-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large portion of the paved highways in the United States are located in regions which experience freezing temperatures. It is well known that under extremely cold temperatures asphalt concrete pavements will undergo thermal stresses sometimes resulting in thermal cracking. An asphalt pavement that has developed thermal cracks in its wearing surface will experience a reduction in service life precipitating higher maintenance and rehabilitation costs. Therefore, one method of providing better quality highways at a reduced cost is to design asphalt pavements that can resist thermal cracking. In an attempt to further characterize the effects of cold temperatures on asphalt pavement the Federal Highway Administration (FHWA) authorized the construction of WesTrack. WesTrack is the FHWA's newest pavement testing facility located outside Reno, Nevada. The primary purpose of WesTrack is to serve as a working field laboratory for the development of Performance-Related Specifications (PRS) . A secondary purpose of WesTrack is to serve as field validation of Superpave mix design and performance prediction concepts. It is anticipated that Superpave will provide a more reliable method of binder selection and minimize thermal cracking of asphalt concrete pavement.
Book Synopsis Evaluation of Low Temperature Cracking in Asphalt Pavement Mixes by : Khaled Ksaibati
Download or read book Evaluation of Low Temperature Cracking in Asphalt Pavement Mixes written by Khaled Ksaibati and published by . This book was released on 1998 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report examines the feasibility of using the thermal stress restrained specimen test to evaluate low temperature cracking in asphalt pavement mixes. Data were collected from laboratory and field evaluations. Various mixing, aging, and compaction methods were used to prepare test samples with materials obtained from two Wyoming Department of Transportation (WYDOT) highway projects. Field data were obtained from two recently built test sections and compared with laboratory test results. Pavement condition surveys quantified low temperature cracking of both test sections after one winter. Temperature data for the project sites also were collected. Pavement condition and temperature data were compared to results from the thermal stress restrained specimen test. The thermal stress restrained specimen test was effective in testing asphalt pavement mixes. However, test results indicated that lab prepared samples did not closely simulate field samples. Also, comparisons of lab results with field conditions were performed. However, it is recommended that a more comprehensive analysis be performed after test sections have been in service for a few years.

Book Synopsis Characterization of Wisconsin Mixture Low Temperature Properties for the AASHTO Mechanistic-empirical Pavement Design Guide by : Ramon Francis Bonaquist
Download or read book Characterization of Wisconsin Mixture Low Temperature Properties for the AASHTO Mechanistic-empirical Pavement Design Guide written by Ramon Francis Bonaquist and published by . This book was released on 2011 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research evaluated the low temperature creep compliance and tensile strength properties of Wisconsin mixtures. Creep compliance and tensile strength data were collected for 16 Wisconsin mixtures representing commonly used aggregate sources and binder grades. Engineering and statistical analyses were performed on the data to provide recommendations for using measured mechanical properties in thermal cracking analyses with the Mechanistic-Empirical Pavement Design Guide (MEPDG), and to evaluate the thermal fracture resistance of Wisconsin mixtures.
Book Synopsis Low-temperature Cracking by : D. H. Jung
Download or read book Low-temperature Cracking written by D. H. Jung and published by Strategic Highway Research Program (Shrp). This book was released on 1994 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thermal stress restrained specimen test (TSRST) was developed to determine the thermal, or the low-temperature cracking resistance of asphalt concrete mixes. The test system is capable of cooling an asphalt concrete specimen at a constant rate, while restraining the specimen from contraction and periodically measuring elapsed time, specimen surface temperature, and tensile load. TSRST's were performed on both short- and long-term aged specimens. Statistical analyses were performed on the test results. Rankings of asphalt concrete mixtures based on fracture temperature were compared to rankings based on fundamental properties of the asphalt cement.
Book Synopsis Elasto-Plastic Fracture Characterization of Paving Materials at Low Temperatures by : K. Mahboub
Download or read book Elasto-Plastic Fracture Characterization of Paving Materials at Low Temperatures written by K. Mahboub and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A methodology for characterization of low-temperature fracture behavior of paving mixtures is presented. The critical elasto-plastic energy release rate, the JIc parameter, is adopted as the fracture criterion. The methodology permits the study of fracture in plasticized sulfur (Sulphlex) and asphaltic paving mixtures. To accommodate special fracture characteristics of pavement materials, certain modifications to the standard ASTM fracture testing procedures are proposed. The rationale for these modifications is also discussed. Approximate values of KIc, KQ, are correlated to the JQ measurements, which are a provisional representation of JIc, and results are compared with theoretical predictions. Tearing modulus is also investigated. The overall results of this study indicate that the JQ parameter can be effectively utilized for characterization of thermal cracking susceptibility of pavement materials.
Book Synopsis Low-temperature Cracking by : Hannele K. Kanerva
Download or read book Low-temperature Cracking written by Hannele K. Kanerva and published by National Research Council. This book was released on 1994 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the field validation program was to evaluate the thermal stress restrained specimen test (TSRST) as the accelerated performance test to predict low-temperature cracking of asphalt concrete mixtures. Construction histories, cracking observations, and temperature data were collected for five test roads. In addition, a validation program was conducted at the United States Army Cold Regions Research and Engineering Laboratory. The laboratory test program consisted of performing the TSRST on specimens fabricated in the laboratory with original materials from the test roads and asphalt concrete pavement specimens cut from the actual test sections. In addition, the field pavements were monitored for crack history and, where possible, crack initiation. TSRST fracture temperature correlated with field cracking temperature and crack frequency. TSRST results can be used to predict field low-temperature cracking of asphalt-aggregate mixtures. Preliminary models to predict cracking frequency and temperature for the test roads were developed.
