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.

Stripping has long been recognized as a cause of asphalt pavement damage. Water may get between the asphalt film and the aggregate surface, causing an adhesive failure, or water may combine with the asphalt to affect the cohesive strength of the material. Various types of antistripping additives have been used in the attempt to alleviate or eliminate stripping. The Virginia Department of Transportation has used antistripping additives in some of its asphalt mixes since the 1960's. In the 1980's hydrated lime was found to outperform several al chemical additives. VDOT began to require asphalt contractors to use chemical additives that produced test results equal or superior to hydrated lime. Presumably, chemical additives were then improved to compete with hydrated lime. This study was undertaken to find if the new generation of additives prevented stripping in Virginia's hot mix asphalt. Twelve test sections were established, 9 using chemical additives and 3 containing hydrated lime. After 3 to 4 years, eight of the sections containing chemical additive demonstrated considerable visual stripping in cores. The sections containing hydrated lime showed much less stripping. The TSR test used on mix sampled during construction did not accurately predict the stripping that occurred. A follow-up survey of existing pavements should be conducted to verify the possible inadequacy of some chemical additives. Also, the TSR test should be examined and possibly modified to more closely duplicate Virginia's environmental conditions.

The purpose of this investigation was to determine the influence of the procedures used in handling asphalt-additive blends on the effectiveness of antistripping additives in asphaltic concrete. The additives were blended with the asphalt cements before shipment by tank truck to the hot mix plants. Laboratory tests were performed on samples of the asphalt cement obtained prior to the blending process at the terminal and after blending and shipment by tank truck to the hot mix plant. Quick bottle tests and infrared spectrophometer tests were used to determine the presence and approximate amount of additive, respectively. A stripping test was performed to determine the effectiveness of the additive. The results of this limited investigation indicate that the present procedure of blending asphalt and antistripping additive before shipment to the hot mix plant is satisfactory; however, long periods of storage at high temperatures might cause the additive to lose part of its effectiveness.

A previous field study of 12 pavements revealed considerable stripping in the surface layers of mixtures placed in 1991-92. Most of the mixes containing chemical additives showed visual stripping, but the ones containing hydrated lime did not show significant stripping. This study was a broad field survey with cores taken from each of the nine VDOT districts. The purpose was to get a better estimate of stripping in Virginia than that of the earlier study. Significant visual stripping was detected in many sites, which verified the fmdings of the earlier study. However, in this study, hydrated lime performed no better than chemical additives. The SM-2A 50-blow mixes with slightly more asphalt performed no better than the SM-2B or SM-2C 75-blow mixes. Pavement voids at many sites were too high for good durability, and the compaction and mix design specifications should be examined. The degree of stripping damage in underlying layers could influence performance at many sites.
