This book was released on 2002 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: In May 2000, the Colorado Department of Transportation (CDOT) requested a forensic study of a project located on I-24 north of Denver. The request was made because, within a year of the 1997 overlay, longitudinal cracking appeared in the surface. Transverse cracks were attributed to reflective cracking. However, the longitudinal cracks appeared to be surface initiated. In October 2000, a forensic team reviewed the project and established a sampling and testing plan to take cores from the roadway. Based on data analysis of the cores, the higher than expected in-place air voids, the low effective asphalt, and segregation within the mat, all contributed to the early cracking.

Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 752: Improved Mix Design, Evaluation, and Materials Management Practices for Hot Mix Asphalt with High Reclaimed Asphalt Pavement Content describes proposed revisions to the American Association of State Highway and Transportation Officials (AASHTO) R 35, Superpave Volumetric Design for Hot Mix Asphalt, and AASHTO M 323, Superpave Volumetric Mix Design, to accommodate the design of asphalt mixtures with high reclaimed asphalt pavement contents.
Download or read book Evaluation of Test Methods for Stiffness Properties of Hot Mix Asphalt HMA written by Stephen Alan Cross and published by . This book was released on 2004 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current 1993 AASHTO "Design Guide for Design of Pavement Structures" uses resilient modulus to assign an "a" coefficient to hot mix asphalt (HMA) to determine the required thickness of the HMA layer for a given traffic loading and subgrade support condition. There are several methods to determine the modulus of a mix for use in determining the "a" coefficient. Modulus results are a function of the test method and curing conditions. Therefore, the test method and curing conditions would have an effect on the "a" coefficient used in thickness design and, hence, the thickness of the pavement layers. A need was voiced by the Kansas Department of Transportation (KDOT) to evaluate the available test methods for determination of the stiffness properties of HMA.

This book was released on 2012-10-17 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This STAR on asphalt materials presents the achievements of RILEM TC 206 ATB, acquired over many years of interlaboratory tests and international knowledge exchange. It covers experimental aspects of bituminous binder fatigue testing; the background on compaction methods and imaging techniques for characterizing asphalt mixtures including validation of a new imaging software; it focuses on experimental questions and analysis tools regarding mechanical wheel tracking tests, comparing results from different labs and using finite element techniques. Furthermore, long-term rutting prediction and evaluation for an Austrian road are discussed, followed by an extensive analysis and test program on interlayer bond testing of three different test sections which were specifically constructed for this purpose. Finally, the key issue of manufacturing reclaimed hot mix asphalt in the laboratory is studied and recommendations for laboratory ageing of bituminous mixtures are given.

Download or read book Evaluation of Hot Mix Asphalt Moisture Sensitivity Using the Nottingham Asphalt Test Equipment written by R. Christopher Williams and published by . This book was released on 2010 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavements are subjected to different stresses during their design lives. A properly designed pavement will perform adequately during its design life, and the distresses will not exceed the allowable limits; however, there are several factors that can lead to premature pavement failure. One such factor is moisture sensitivity. AASHTO T 283 is the standard test used in the moisture susceptibility evaluation of asphalt mixtures, but the results of the test are not very representative of the expected behavior of asphalt mixtures. The dynamic modulus test measures a fundamental property of the mixture. The results of the dynamic modulus test can be used directly in the Mechanistic-Empirical Pavement Design Guide (MEPDG) and are considered a very good representation of the expected field performance of the mixture. Further research is still needed to study how the dynamic modulus results are affected by moisture. The flow number test was studied in previous research as a candidate test for moisture-susceptibility evaluation, but the results of that research were not favorable. This research has four main objectives. The first objective of this research is to evaluate the usefulness of the dynamic modulus and flow number tests in moisture-susceptibility evaluation. The second objective is to compare the results to those achieved using the AASHTO T 283 test. The third objective is to study the effect of different methods of sample conditioning and testing conditions. The fourth objective of the research is to study the variability in the test results.
