Abstract

Moisture damage in asphalt mixtures generally occurs due to the separation of bitumen from the surface of stone materials and due to the presence of water. This type of failure causes stripping and premature failures. Investigating the effective factors in this type of damage can be useful in improving the process of designing and producing asphalt mixtures. In the past years, significant research and efforts have been made to reduce these types of failures. In this article, the effect of adding Polytec 505, as a new material with complex amines that reduce the acidic nature of bitumen, on the moisture damage of asphalt mixtures has been investigated. For this purpose, two types of granite and lime aggregate and 60-70 bitumen have been used. The modified Lottman test was used to check the moisture damage, and pull-off tests were used to evaluate the cohesion properties of bitumen and the adhesion of bitumen to aggregate. The results show that the use of this additive causes an increase in the indirect tensile strength ratio of samples with granite and limestone aggregate, and as a result, the performance of these samples against moisture damage improves. This improvement increases with the increasing of this additive. The results of the Pull-off test show that the use of this additive improves the adhesion and cohesion of pull-off pull off test.
