摘要
In order to improve the performance of granite asphalt mixtures, as well as make full use of waste concrete, the AC-25 asphalt mixtures were prepared using fine recycled concrete aggregate and coarse granite aggregate. The moisture stability, high-temperature property, low-temperature property and fatigue property of asphalt mixtures were investigated. Results indicate that fine recycled concrete aggregate (RCA) improves the moisture stability and low-temperature property of granite asphalt mixtures which can meet the requirements of China’s Technical Specification for Construction of Highway Asphalt Pavements (JTG F40-2004) and even are better than those of traditional limestone asphalt mixtures. Meanwhile, fine RCA makes the advantage of granite asphalt mixtures in high-temperature property more distinct with good fatigue property.
