路面的弯沉检测是我国柔性路面强度测量的一项主要指标。路面弯沉是指在规定的标准轴载作用下,路面表面轮隙位置产生的总垂直变形或垂直回弹变形值。它不仅反映路面各结构层及土基的整体强度和刚度,而且与路面的使用状态存在一定的内在联系。现对此进行了分析和探讨,并建议建立一套专用于计算施工检验弯沉的数学公式来进一步完善道路工程的质量验收。
Pavement deflection detection is a major indicator of the strength measurement of flexible pavement in our country. Road surface deflection refers to the total vertical deformation or vertical rebound deformation value caused by the position of the road surface under the specified standard axle load. It not only reflects the overall strength and stiffness of pavement structure and soil foundation, but also has an inherent relationship with the use status of pavement. Now it is analyzed and discussed, and it is suggested to establish a mathematical formula dedicated to calculating the deflection of construction inspection to further improve the quality acceptance of road engineering.
