Method for evaluating skid resistance of steel slag asphalt mixture pavement wearing layer
The invention relates to a steel slag asphalt mixture pavement wearing layer anti-slide performance evaluation method, which comprises: obtaining a modeling sample of a steel slag asphalt mixture pavement, and carrying out wearing under a set load for different times to obtain modeling samples with different wearing degrees; recording a friction factor mu, a macroscopic texture parameter and a microscopic texture parameter under each set action frequency; establishing a correlation model between the friction factor and the macroscopic texture as well as the microcosmic texture, and establishing a friction coefficient decay rule prediction model associated with the friction coefficient and the load action times; drawing a curve, and selecting a critical value mu a according to a curve rule; obtaining a to-be-evaluated sample of the pavement, testing macroscopic texture parameters and microscopic texture parameters of the to-be-evaluated sample, and substituting the macroscopic texture parameters and the microscopic texture parameters into the correlation model to obtain a test friction factor mu ce; and performing evaluation according to the friction factor mu ce. Compared with the prior art, the method has the advantages of being high in measurement speed, full in information amount, visual and vivid, capable of accurately reflecting surface three-dimensional shape information and the like.
本发明涉及一种钢渣沥青混合料路面磨耗层抗滑性能评价方法，包括：获取钢渣沥青混合料路面的建模样本，在设定荷载下作用不同的次数进行磨耗，得到不同磨耗程度的建模样本；记录在各个设定作用次数下的摩擦因数μ、宏观纹理参数和微观纹理参数；建立摩擦因数与宏观纹理、微观纹理之间的相关性模型，以及建立摩擦系数与荷载作用次数关联的摩擦系数衰变规律预测模型；绘制曲线，根据曲线规律选择临界值μa；获取路面的待评价样本，测试其宏观纹理参数和微观纹理参数，代入相关性模型得到测试摩擦因数μce；根据摩擦因数μce进行评价。与现有技术相比，本发明具有测量速度快、信息量全、直观形象、精确地反映表面三维形貌信息等优点。
