This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Moisture susceptibility of hot mix asphalt (HMA) pavements continues to be a major pavement distress. Past research has primarily focused on HMA stripping prevention through material component evaluation/testing and addition of preventative additives. Stripping is caused by traffic, water, and high in-place service temperatures. Today, agencies use various methods to evaluate HMA moisture susceptibility with varying degrees of success. The study objective was to evaluate a prototype stripping simulator's ability to predict HMA moisture susceptibility. The simulator evaluates moisture susceptibility by measuring conditioning water turbidity. Boil test and indirect tensile strength testing were also conducted for comparison purposes. Stripping simulator results indicate further refinement is required before it can be used for moisture susceptibility prediction.

Download or read book Accelerated Pavement Testing to Transport Infrastructure Innovation written by Armelle Chabot and published by Springer Nature. This book was released on 2020-08-25 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume gathers the latest advances, innovations, and applications in the field of accelerated pavement testing (APT), presented at the 6th International Conference on Accelerated Pavement Testing, in Nantes, France, in April 2022. Discussing APT, which involves rapid testing of full-scale pavement constructions for structural deterioration, the book covers topics such as APT facilities, APT of asphalt concrete and sustainable/innovative materials, APT for airfield pavements, testing of maintenance and rehabilitation solutions, testing of smart and multi-functional pavements, data analysis and modeling, monitoring and non-destructive testing, and efficient means of calibrating/developing pavement design methods. Featuring peer-reviewed contributions by leading international researchers and engineers, the book is a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of pavement structures during their service life (10+ years) in a few weeks or months.

Available in PDF, EPUB and Kindle. Book excerpt: The use of hydrated lime or other liquid anti stripping agents (ASA) is the most common method to improve the moisture susceptibility of asphalt mixes. However, most laboratory test conditions used to evaluate the moisture susceptibility of the mixes are only for a short duration of time. This might not be a good representation of the field conditions (i.e., several months or years of service). Thus, a study to evaluate the effects of conditioning the mixes for longer durations was initiated. Also, another problem with the use of the liquid anti stripping agents is their heat storage stability. This report addresses these two issues, by preparing and testing mixtures made with fresh binder for indirect tensile strength after conditioning the samples for 1, 7, 28, 90 and 180 days, and samples prepared from binder stored for three days at 160° C after conditioning them for 1, 28 and 90 days. The results of this study indicated that hydrated lime and the liquid anti stripping agents were equally effective for the mixes used in this research when conditioned beyond one day. In the case of samples prepared from stored binder, there was no significant difference in the effectiveness of hydrated lime and the liquid anti stripping agents even after conditioning for one day. Though it was observed that none of the ASA treatments performed better than others in the case of samples prepared with stored binder, it was also observed that almost all mixes gave significantly similar wet ITS and TSR values as samples prepared from fresh binder.

Download or read book Stripping of Asphalt Concrete written by Frazier Parker and published by . This book was released on 1987 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The freeze thaw stress pedestal test, the boil test and the indirect tensile test were evaluated for assessing the stripping potential of typical Alabama asphalt concrete mixes and the effectiveness of antistripping additives. This was accomplished by testing surface and base/ binder mixes with five aggregate combinations, two sources of asphalt cement and three antistripping additives. Because of the test complexity and lack of a strong correlation with stripping performance, the freeze thaw stress pedestal test is not recommended. The boil and indirect tensile tests, in combination, offer a viable, although, imperfect, system for stripping evaluation. The lack of a strong correlation with reported field performance detracts from both tests. However, the imprecise and subjective nature of the reported performance and the correlations obtained by others are mitigating factors.

This book was released on 1990 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this literature review is to search the literature in the area of chemical and mineral agents used to promote adhesion of asphalt-aggregate mixes. In addition, tests performed to measure the effectiveness of these agents were reviewed. The information gained through this literature search and review provides background information for the research being performed in the SHRP A-003B contract. This literature search was performed using on-line chemical abstracts for documents in the time period of 1967 to present.

This book was released on 1994 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a brief summary of the processes that led to the selection of performance-related tests to define asphalt-aggregate interactions that result in fatigue, permanent deformation, thermal cracking, aging, and water sensitivity. Inherent in this test selection process was the emphasis on the ability of the tests to measure fundamental material properties that, when incorporated into prediction models, will depend less on empirical correlations than has been traditionally the case. Also included are the results of validation studies for each of the tests and frameworks for the use of the tests in mix design and analysis. Several levels of design are provided for each distress, some of which incorporate reliability concepts.
