旧水泥混凝土再生集料作水稳基层路用性能改善研究

Research on Road Performance Improvement of Recycle Concrete Aggregate as Cement Stabilized Base Course

旧水泥混凝土再生集料改善主要解决再生集料吸水率问题。对再生集料的基本性能研究分为普通再生集料和球磨再生集料。水稳再生集料的抗压强度试验包括击实试验和无侧限抗压强度试验。水泥稳定再生集料的干燥收缩率是评价结合料耐久性的一个重要指标。

Improvement of recycled aggregate of old cement concrete is mainly to settle the issue of water absorption rate. Study on the basic properties of recycled aggregate is divided into ordinary recycled aggregate and milling one. The compressive strength test of water stable aggregate includes compaetion test and unconfined compressive strength test. Drying shrinkage of cement stabilized recycled aggregate is an important indicator to e- valuating the binding material durability.
