关于沥青路面弯沉检测温度修正的探讨

Discussion on temperature correction for deflection detection of asphalt pavement

随着城市化进程的不断发展,目前多数大中城市都在进行大量的道路施工,弯沉检测是评定沥青路面的整体承载能力的依据之一,所以温度修正系数计算的准确性至关重要。而且现今多数道路工程采用ATB沥青稳定碎石代替刚性或半刚性材料作为基层,需要探讨在进行路面弯沉检测过程中是否应计入该层对温度修正系数的影响。

With the continuous development of urbanization, most large and medium-sized cities are carrying out road construction and reconstruction at present. Deflection detection is one of the bases for evaluating the overall bearing capacity of asphalt pavement, so the accuracy of temperature correction coefficient calculation is of great importance. And nowadays most road projects using ATB asphalt stabilized macadam instead of rigid or semi-rigid material as base, we need to discuss in the process of pavement deflection tests, whether the layer effects on temperature correction coefficient should be included.
