在第十六届国际道路会议上,有史以来首次广泛地讨论了人造材料、工业生产废料和副产品在道路建造中的使用问题。路基材料路基上层承载力大就能够改进路面结构层的铺设和夯实条件,减小各结构层的厚度,提高路面强度和耐磨性。例如在法国,粒状材料已可节省60％,这样不仅降低了建造费用,并且还由于缩小了取土坑面积,而减少了对周围环境的影响。
For the first time ever, at the 16th International Road Conference, the use of man-made materials, industrial production wastes and by-products for road construction was extensively discussed. Subgrade upper embankment bearing capacity can improve the pavement structure pavement laying and ramming conditions, reducing the thickness of each structural layer, improve road strength and wear resistance. In France, for example, granular materials have been saved by 60%, which not only reduces construction costs but also reduces the impact on the surrounding environment by reducing the area of borrow pits.
