Use of local aggregates in high modulus asphalt concrete layers

Abstract

High value of traffic flow influenced the need to build long lasting pavement structures with design life of more than 20–40 years. Current budget for maintenance and reconstruction is not sufficient for preventing the rutting on the existing asphalt pavement roads and streets. These factors lead to search for new materials, mixtures, and methods for preparation of asphalt mixes. The high modulus asphalt concrete is regarded as one of possible solutions. The laboratory study of the high modulus asphalt concrete with different types of bitumen binder and mineral aggregates is presented in the paper.
