Temperature and speed correction method for asphalt pavement deflection measured by high-speed deflectometer
The invention discloses a temperature and speed correction method for asphalt pavement deflection measured by a high-speed deflectometer, and relates to the technical field of road engineering, and the method comprises the following steps: using the high-speed deflectometer to test deflection of each point of an asphalt pavement; calculating the deflection temperature correction coefficient of each point; calculating a deflection speed correction coefficient of each point; calculating a temperature and speed correction result of deflection of each point; the asphalt pavement deflection measured by a high-speed deflectometer is corrected to a standard state when the temperature of an asphalt mixture surface layer is 20 DEG C and the detection speed of the high-speed deflectometer is 80km/h, reference can be provided for the deflection detection of the asphalt pavement based on the high-speed deflectometer, and the existing speed correction and temperature correction method in the highway roadbed pavement field test regulation (JTG 3450-2019) is lacked. The application of the deflection data of the asphalt pavement measured by the high-speed deflectometer is limited, and the method disclosed by the invention fills up the vacancy and is conveniently applied to the deflection detection of the asphalt pavement by the high-speed deflectometer.
本发明公开了一种高速弯沉仪所测沥青路面弯沉的温度速度修正方法，涉及道路工程技术领域，包括以下步骤：应用高速弯沉仪测试沥青路面的各点弯沉；计算各点弯沉的温度修正系数；计算各点弯沉的速度修正系数；计算各点弯沉的温度速度修正结果；将高速弯沉仪所测沥青路面弯沉修正至沥青混合料面层温度为20℃、高速弯沉仪检测车速为80km/h时的标准状态，可为基于高速弯沉仪的沥青路面的弯沉检测提供参考，现行《公路路基路面现场测试规程》（JTG 3450‑2019）中速度修正与温度修正方法的缺少，限制了高速弯沉仪所测沥青路面弯沉数据的应用，本发明方法则填补了上述空缺，便于在高速弯沉仪沥青路面弯沉检测中应用。
