摘　　要：通过大量的试验数据证明,JTGE 42—2005《公路工程集料试验规程》中的压碎值相关关系式不适合鄂东山区的片麻岩粗集料。参照T0316—2005中相关关系式制订的依据及方法,通过线性回归分析的方法,对比和分析鄂东山区片麻岩石样的新旧试验方法压碎值数据,建立适合当地片麻岩粗集料的压碎值相关关系式。A lot of test data proved that relevant relational expression in crushing value test method T0316-2005 of ＂Highway Engineering Test Aggregate of Order＂ is not proper for the gneiss coarse aggregate of the east mountain area of Hubei Province.According to basis and method of the relevant relational expression in which T0316-2005 drawn up,by linear regression analysis,the relevant relational expression which is proper for the local gneiss coarse aggregate through comparing and analyzing crushing value data of the local representative gneiss coarse aggregate in the new and old rules is acquired.

关 键 词：片麻岩 粗集料 压碎值 相关关系式
