The effect of cement as a filler in reducing the moisture sensitivity of hot mixed asphalt
Abstract
Moisture is one of the most important reasons of asphalt stripping. The removal of moisture effects on hot mixed asphalts is one of the most important problems in pavement engineering; one solution to reach this goal is the use of different kinds of additives during mixture procedure. Portland cement can be used as a substitute of filler in hot mixed asphalt. In this paper the results of a research program conducted to evaluate the effect of cement in reducing the moisture sensitivity of asphalt are presented. The experiments of this research are designed to assess the effect of long term humidity conditioning on hot mixed asphalt. The results indicate that the effect of cement in reducing the water susceptibility of asphalt strength is time dependent and anti stripping effects in early stages after mixture is not considerable.The results reveal that cement has a suitable long term moisture sensitivity reducing effect which can be attributed to the time dependence of chemical reactions.
