Evaluation of Warm Asphalt Destruction Using Mountain and Fluvial Aggregate

Roads are National resources of countries and every year large costs are spent to maintain and repair of them. Destruction of Asphalt is one of the main problems in the maintenance of roads. In this regard¡ durability and reliability of asphalt is depended to its Characteristics of aggregates and construction. There are always some reasons for early destruction of asphalt. Materials resistant to traffic¡ weather conditions and the adhesion of bitumen to aggregate¡ are the main factors affecting the sustainability and durability of asphalt. Improper use of aggregates and bitumen and its poor performance lead to stripping materials¡ which cause damage to asphalt. In this study¡ two types of asphalt are made using mountain and fluvial materials and their operation was investigated under heavy traffic load. At last¡ possible solutions are suggested to resolve the potential problems.
