《公路工程集料试验规程》(2005年版)中粗集料压碎值相关关系式有一定的局限性,通过大量试验证明此关系式并不适合青州临朐一带石灰岩类粗集料压碎值的换算。文章通过对新老试验方法所得压碎值数据进行对比分析,建立适合这一带石灰岩类粗集料的压碎值相关关系式。
The correlation formula of crush value of coarse aggregates has some limitations in the Code for Highway Engineering Aggregate Testing (2005 Edition), and the results show that this relationship is not suitable for the crushing value of coarse aggregates of limestone in Linqu area of Qingzhou Conversion. By comparing the crushed value data obtained from the old and new test methods, the paper establishes the correlation between the crushed value of limestone coarse aggregate suitable for this area.
