This book was released on 1993 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of a long-term field evaluation of the effectiveness of lime and various antistripping agents. This research study was a continuation of the research carried out between 1986 and 1991 (documented in CTR Research Reports 441-1 and 441-2F). Core samples were obtained from the field test sections and tested in the laboratory based on Test Methods Tex-531-C and AASHTO T283. Test results did not indicate any consistent pattern with regard to effectiveness of certain antistripping additives versus others. The field test sections, treated with antistripping agents and built in eight districts of the Texas Department of Transportation, were monitored for signs of distress during the course of the research study.

This book was released on 1991 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarized the results of field evaluation of the effectiveness of lime and various antistripping additives using the following methods: (a) Modified Lottman Method (Tex-531-C) and (b) Boiling Test (Tex-530-C). Core samples were obtained from the field test sections up to 48 months after construction. Field data to date show very little evidence of distress which is directly related to moisture damage or stripping. This was anticipated due to the slow rate of moisture ingress under adequate construction compaction.

Book Synopsis Moisture Damage in Asphalt Concrete by : Russell G. Hicks
Download or read book Moisture Damage in Asphalt Concrete written by Russell G. Hicks and published by Transportation Research Board. This book was released on 1991 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement designers, construction engineers, maintenance engineers, and others interested in avoiding or limiting moisture damage in asphalt concrete. Information is provided on physical and chemical explanations for moisture damage in asphalt concrete, along with a discussion of current practices and test methods for determining or reducing the susceptibility of various asphalt concrete components and mixtures to such damage. Moisture damage in asphalt concrete is a nationwide problem which often necessitates premature replacement of highway pavement surfaces. This report of the Transportation Research Board describes the underlying physical and chemical phenomena responsible for such damage. Current test methods used to determine the susceptibility of asphalt concretes, or their constituents, to moisture damage are described and evaluated. Additionally, current practices for minimizing the potential for moisture damage are examined.
Book Synopsis Evaluation of Anti-stripping Agents Using the Asphalt Pavement Analyzer by : Stephen A. Cross
Download or read book Evaluation of Anti-stripping Agents Using the Asphalt Pavement Analyzer written by Stephen A. Cross and published by . This book was released on 2001 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Moisture damage of asphalt mixes, better known as stripping, is a major distress affecting pavement performance. AASHTO T 283 (KT-56) has been used by many agencies over the past decade to detect moisture susceptible pavements through the determination of a tensile strength ratio (TSR). Results from AASHTO T 283 (KT-56) have been inconsistent. As a result, there has been increased interest in finding an alternative test method. Preliminary indications reveal that loaded wheel rut testers, such as the Asphalt Pavement Analyzer (APA), have the potential to detect moisture susceptible mixtures. To date no standard test methodology has been developed. The objective of this project was to evaluate the effects of sample preconditioning on APA rut depths and to further evaluate the APA's suitability for predicting moisture susceptible mixtures. Eight different mixes from seven project sites were evaluated with the APA. Samples were tested at 40 deg C using four different preconditioning procedures: dry, soaked, saturated, and saturated with a freeze cycle. The results were compared with TSR values, methylene blue values and sand equivalent. The APA was able to identify every mix with a failing TSR.
Book Synopsis Laboratory Evaluation of Anti-strip Additives in Hot Mix Asphalt by : Bradley J. Putnam
Download or read book Laboratory Evaluation of Anti-strip Additives in Hot Mix Asphalt written by Bradley J. Putnam and published by . This book was released on 2006 with total page 178 pages. 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.

Book Synopsis Statistical Evaluation of Additive Effectiveness in Asphalt Paving Mixtures by : WV. Ping
Download or read book Statistical Evaluation of Additive Effectiveness in Asphalt Paving Mixtures written by WV. Ping and published by . This book was released on 1994 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt pavements are susceptible to moisture damage. One of the procedures to eliminate or minimize the damage is to treat the asphalt paving mixtures with an antistripping agent such as hydrated lime or other commercially available antistripping additives. Statistical analysis is essential to evaluate the effectiveness of various treatments in asphalt mixtures. This paper summarizes a research study to evaluate the effectiveness of asphalt treatments utilizing statistical pairwise comparisons. The approach is to use the boiling test results to do the statistical comparison.

Book excerpt: A technical review of moisture damage of asphalt pavements and antistripping additives has beencompleted as part of a review and testing study for the Transportation Association of Canada that has the objective of developing a Canadian manual on the assessment of moisture susceptibility and selection of antistripping additives. The review is based on practical asphalt technology experience, questionnaires to agencies and asphalt cement suppliers, and the technical literature on moisture damage of asphalt pavements. Methods of mitigating moisture damage in asphalt pavement structures, in addition to the use of antistripping additives, such as drainage, compaction, aggregates selection, mix designs and quality control, were reviewed in terms of stripping mechanisms and causes. The Strategic Highway Research Program has involved considerable research on the moisture susceptibility of asphalt concrete and appropriate laboratory procedures to assess moisture damage. Qualitative and quantitative (strength) tests for assessing the moisture susceptibility of hot-mix asphalt mixes are reviewed. There is strong technical support for the Tunnicliff-Root (ASTM D 4867), Modified Lottman (AASHTO T 283) and Ontario MTO Immersion Marshall (LS-283) tests. The use of liquid (amines generally) and hydrated lime antistripping additives is considered. There is considerable technical information on the comparative efficacy of hydrated lime as an antistripping additive. An important area of research need is appropriate quality control/quality assurance to monitor the field effectiveness of antistripping additives. For the covering abstract of this conference see IRRD number 872978.
