Parseh Designers Transportation Research Institute Quarterly Journal of Transportation Engineering 2008-6598 2 1 2010 09 23 Effect of Basalt Aggregate on Performance of Concrete Asphalt Mix,Containing Limestone Effect of Basalt Aggregate on Performance of Concrete Asphalt Mix,Containing Limestone 13 25 1569 FA Journal Article 2012 08 04 HMA is a mixture of aggregates and liquid bitumen. Aggregates that include both fine and coarse materials, stand for more than %95 of HMA mixtures by weight. The main role of aggregates in the mixture is to convey the traffic load to the layers beneath, therefore the specifications of aggregates significantly affect the mixture properties, specially rutting and stripping. In this experimental project conducted at Iran University of Science and Technology, Bitumen and Asphalt Mixture Center, two sets of specimens were made and defined. The first group of specimens was made with lime aggregate and in the second group, coarse aggregates were replaced by basalt. Comparison was done against rutting, durability, and resilient modulus and Marshal Stability tests. Results show that specimens made with %100 lime material demonstrate better performance compared to specimens containing basalt. HMA is a mixture of aggregates and liquid bitumen.
