我国《公路工程集料试验规程》（JTG E42-2005）中同时提供了粗集料压碎值、洛杉矶磨耗损失和冲击值试验方法。三者虽从不同侧面反映了粗集料抵抗外力的能力，但皆为力学指标。为探究三者之间相关性，按照该标准规定的试验方法，对安徽省不同产地粗集料的压碎值、洛杉矶磨耗损失和冲击值进行了试验研究。结果表明其两两之间存在相关性，并给出了相关关系式，为今后通过其中任一项试验结果推算另两项试验结果提供了参考，也为今后标准及规范减少或合并粗集料试验项目及质量指标进行了有益探索。

"Test Methods of Aggregate for Highway Engineering"(JTG E42-2005) provides the test meth-ods of the crushed value, the Losangeles weared value and the impact value of coarse aggregate. Although the three reflect the performance of the coarse aggregate against external forces, but they are all mechani-cal indexes. For inquiry the correlation between the three, according to the test methods formulated by standards, the crushed value, the Losangeles weared value and the impact value of coarse aggregates in different regions of Anhui Province are studied through tests. The research results show that there are cor-relation between any two, and the relevant equations are obtained, which provides reference for reckon the other two indexes based on any one test of the three, and also explores how to reduce or merge coarse aggregate test items and quality indexes in standards and norms in future.
