RECYCLED COLD ASPHALT CONCRETE MIXTURE AND METHOD FOR CONSTRUCTING ASPHALT CONCRETE BY USING SAME

摘要

The present invention relates to a recycled cold asphalt concrete mixture, and to a method for constructing asphalt concrete by using the same. More specifically, the present invention relates to a recycled cold asphalt concrete mixture having improved durability, and to a method for constructing asphalt concrete by using the same. A modified additive and emulsified asphalt are mixed with an aggregate, so the recycled cold asphalt concrete mixture of the present invention has improved physical properties compared to conventional recycled cold asphalt concrete. An aggregate is uniformly mixed, and adhesion between aggregates is improved, so the recycled cold asphalt concrete mixture of the present invention has enhanced internal cohesion. Waste asphalt concrete which is industrial waste is recycled to be industrially usefully used, so the environment can be protected and economic feasibility can be improved. Moreover, when asphalt concrete is constructed, occurrence of atmospheric environment contaminants such as dust, carbon dioxide, nitrogen, and sulfuric acid caused when an aggregate is heated is controlled compared to a heated asphalt mixture scheme. Accordingly, an environmentally-friendly road can be constructed, and decreases in quality and functions caused when asphalt is heated, oxidized, and deteriorated can be prevented.;COPYRIGHT KIPO 2016
