莫桑比克沥青路面加铺设计应用研究

结合莫桑比克EN1公路改造实际,按照南部非洲规范的要求,根据现场进行旧路路面弯沉及路基CBR的检测结果,采用地沥青学会方法对路面加铺厚度进行计算与校核,按满足当地公路路面结构强度要求,最终确定路面加铺的类型和厚度,对当地类似公路改造项目具有参考价值。

Study on Application of Overlay Design for Asphalt Pavement in Mozambique

Combining with the practice in reconstruction of EN1 Road in Mozambique, as required by the codes of South Africa, the field investigation was carried out in connection with the old pavement deflection and subgrade CBR and, by use of the Asphalt Institute’s method, the thickness of pavement overlay was calculated and checked, which met the requirements of the local structural strength of pavement. Finally, the type and thickness of the pavement overlay were determined. It has reference value for the local similar road rebuilding projects.
