Book Description
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 Description
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 Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 763: Evaluation of the Moisture Susceptibility of WMA Technologies presents proposed guidelines for identifying potential moisture susceptibility in warm mix asphalt (WMA). The report also suggests potential revisions to the Appendix to AASHTO R 35, "Special Mixture Design Considerations and Methods for WMA" as a means to implement the guidelines."--publisher's description

Book Description
Many factors have been identified to have influences on the moisture susceptibility of asphalt mixtures. This research study attempts to evaluate such factors as binder type, aggregate type, mixture type, additive usage, additive type, additive application approach, and additive organic nature. Tensile strength ratio (TSR) was tested on twelve asphalt mixtures of three types, with two binders and three aggregates, and with improving measures as three antistripping additives and two application approaches. Multiple variable statistical analyses were employed on the TSR data in assessing the significance of the factor. Test results and data analyses indicate that the extent of the influence varies considerably from one factor to another. The styrene-butadiene-styrene modified binder is superior to neat petroleum binder for producing asphalt mixtures subject to damp conditions. Granite, basalt, and limestone aggregates make asphalt mixtures that are least, in-between, and most resistant to moisture damage, respectively. Compared with dense graded asphalt concrete (AC) and stone matrix asphalt (SMA) mixtures, porous asphalt macadam (AM) mixtures are more prone to stripping. The usage of inorganic hydrated lime and Portland cement, and organic amine antistripping agent can substantially improve the moisture susceptibility of asphalt mixtures; the wet approach for applying the inorganic additives can result in better effects than the dry approach. Different additives show little difference in improving effects with mixed trends and the inorganic and organic additives are similar in performance with variations that are immaterial.
