在对非洲滨海公路沿线砂源进行广泛调研的基础上,选取若干典型砂样进行了一系列材料试验与加速加载测试,掌握了非洲滨海公路沿线粉细砂的级配特征、压实特性以及物理力学性能,并评价及验证了其路用性能。研究结果表明:在一定条件下,非洲滨海公路沿线粉细砂的路用性能较好,能够满足工程技术要求,可以作为公路路基填料。 Based on extensive research on the sand source along the coastal road in Africa, a series of material tests and accelerated loading tests were carried out on several typical sand samples to grasp the gradation characteristics, compaction characteristics and physical properties of fine sand along the coastal road in Africa Mechanical properties, and evaluate and verify the road performance. The results show that under certain conditions, the performance of fine sand along the coastal road in Africa is good, which can meet the engineering requirements and can be used as the roadbed filler.
