摘　　要：本文用γ－反散射法对沥青混凝土密度作非破坏性质量控制，分析了组装仪器的最佳工作条件、干扰因素、校正，达到实用阶段，该法特点是测试速度快，有利于质量控制，不取样，费用省，铺筑层整体性有保证．With γ-back scattering method as the non-destructive quality control over the density of bituminous concrete, this article analysed the optimum work conditions and interferingfactors of assembled instrument, and corrected them before the practical stage. The peculiar features of this method are :fast in determination, beneficial to the quality control,low in cost. There is no need for samping, and the wholeness of filled up layers is guaranted.
