بررسي دوام در نمونه هاي آسفالتي ساخته شده با مصالح آهكي

Research and studies has shown that durability of asphalt concrete mixtures is depended upon bituminous film thickness as well as its adhesion to aggregates in the mix. In this paper the effects of two types of fillers namely lime powder and silica power upon strength, durability and also stripping potentials of asphalt concrete mixtures are studied. For this purpose Marshall Test and indirect tensile test is conducted on mixes containing lime power, silica power and also equal proportions of these fillers. The results indicate that mixes containing lime powder will infect have better resistant to freez-thaw actions than mixes containing silica powder.
