AASHTO T 182-84 (2002) PDF Download

AASHTO T 182-84 (2002) is a standard method for testing the coating and stripping of bitumen-aggregate mixtures. It is very similar to the ASTM D1664-80 standard, with some specific provisions outlined in the AASHTO document.

The purpose of this method is to determine the ability of a bituminous film to adhere to an aggregate surface in the presence of water. This is important because the presence of water can cause the bitumen to strip away from the aggregate, leading to reduced pavement performance and durability.

The method involves coating the aggregate with the bituminous material and then subjecting it to a static immersion test. The aggregate is completely immersed in water for a specified period of time. After the immersion period, the aggregate is examined to determine the extent of coating retention.

This method is applicable to different types of bituminous materials, including cutback, emulsified, and semi-solid asphalts and tars. It provides a standardized procedure for evaluating the performance of these materials in terms of their ability to resist stripping when exposed to water.
