CT技术的低水泥含量级配碎石基层材料性能
Properties of low cement macadam base material based on CT technology
摘要
Abstract
In order to study low cement grades macadam base material performance,this paper carried out specimen cross-section scanning test of base material by using of medical CT scanning technology,and obtained a low cement content graded macadam CT images.The macroscopic mechanical failure and internal microscopic changes of graded macadam were studied by image features to obtain the relationship between internal damage and temperature,pore structure and compressive strength.Test results show that the temperature of low cement content of graded aggregate material compressive strength has little effect;using CT scanning technology,this study finds out that the maximum temperature threshold segment is between-15℃ to 30℃.关键词
