二灰碎石基层材料力学性能与路用性能相关性研究

摘要

This paper analyzes the correlations of unconfined compressive strength, compressive modulus, indirect tensile strength, as wel as the base of the unconfined compressive st-rength and crack, rut ing area, patch area ratio and PCI of lim-e-ash macadam base material on a highway, and the correlat-ion is good.%　　本文对某高速公路二灰碎石基层材料的无侧限抗压强度、抗压回弹模量、间接抗拉强度以及底基层的无侧限抗压强度与裂缝度、车辙面积率、修补面积率以及 PCI进行了相关性分析，发现其相关性较为良好。
