Discussion on Quality Control Standard of Asphalt Pavement Compaction Degree
摘要
Abstract
Based on the asphalt pavement construction of Yi-lan and Qi tai-he highway, quality control standards on compaction degree of asphalt concrete pavement was discussed. Results show that, with double standards of Marshall standard density and the theoretical maximum relative density, the actual compaction condition of pavement can be truly and effectively reflected. When a core sample porosity is 4. 12% greater than design porosity, the compaction degree value calculated by Marshall specimens may shows a false illusion of over one hundred, which can not truly reflect the real compaction state of the asphalt pavement. Therefore, it is recommended to calculate the compaction degree with the principle of two quality control standards be consistent with each other. Through the method of mathematical statistics, linear regression can be conducted to K1 , and the compaction degree of K′2 after regression is the real value.关键词
