摘要
文章针对重载和高温条件下沥青路面的车辙问题,采用天然岩沥青作为改性剂,优选矿料级配制备岩沥青改性沥青混合料,对其路用性能进行试验研究与系统评价,为天然岩沥青改性混合料用于沥青路面建设提供技术支持。
Aiming at the rut under heavy traffic and high temperature of the asphalt pavement,nature rock asphalt is adopted as modifier and select gradation limit to prepare modified asphalt mixture in order to study its pavement performance systematically.The construction technology of modified asphalt mixture of natural rock asphalt which have influenced on aging performance is discussed.It provides technical support for the field pavement construction which use asphalt mixture of natural rock asphalt.
