High Modulus Asphalt Concrete with Limestone Aggregate

Utilization of local and alternative materials (such as steel slag) is one of the main aims of the road building. This concerns both developed and developing countries. One can obviously notice changes and the rise of requirements for road pavements and materials applied. This occurrence observed lasting recent years is mainly the result of the growth of the intensity of road transportation. It is an important task to meet the more stringent requirements without excessively increasing the costs. Problems resulted from the limited accessibility of mineral aggregates appeared with the considerable growth of financial expenditures on road construction as well as logistics and transportation problems in delivery of aggregate from quarries located on the south of Poland to northern and eastern regions. This study is devoted to the applicability of using limestone aggregates, available in central and northern Poland, in the asphalt mixtures. Laboratory tests showed that limestone aggregate may be successfully used in High Modulus Asphalt Concrete for base and binder courses of road pavements. This result is also confirmed by full scale testing using a Heavy Vehicle Simulator.
