Abstract:The low temperature maintenance material of rare earth modified asphalt pavement is discussed from rare earth cold repair principle, composition, characteristics, production and application, and also from comparison of various asphalt mixture and economic, social benefits. The practice proves that the new material has advantages of high initial strength, good water resistance, good workability, easy compaction, stable storage, better pavement performance, etc. The application to asphalt pavement repair is getting better effects.
Keywords:highway engineering   pre-mix method   additive of rare earth   asphalt mixture for cold repair
