| 摘 要： | 通过设计5种具有不同抗滑性能的AC—13沥青混凝土,成型室内车辙板并测试其BPN与TD,铺筑现场道面并测试BPN、TD与μ值,通过多元线性回归建立起μ值的预估公式;通过2条道面的抗滑性能数据验证预估公式的可靠性。结果表明,μ值的预估公式具有较高的精度,采用现场实测BPN、TD值计算比用室内车辙试件测得的值计算的μ值与现场实测值更为接近。

| Abstract: | Through designing five different skid resistance performance mixtures, BPN and TD on rutting test-pieces are tested, BPN, TD and I~on site are tested. Using multiple linear regression, the computational formulas are established. The feasibility of computational formulas are checked by project. The conclusion show that the computational formulas are accurate, and theμ calculated by BPN and TD tested on site is more accurate than that calculated by BPN and TD tested on test-pieces. |
