山东泰安公路段在铺筑济南至长清公路的级配路面时,采用了拖拉机牵引多铧犁来拌合级配材料的办法,效果很好。兹将具体做法介绍如下: 一、概况该路长17.2公里,原为拳石底层的碎石路面,因年久失于养护,上层碎石已国光,以致拳石外露,行车颠簸甚剧。后经设计为级配碎石和天然砾石路面,路面厚度5～12公分,单车道宽3.5公尺,路基宽为7.5～9公尺。因旧有拳石在设计中仍做底层,所以在铺料前用12吨压路机碾压还很难压平,仍有拳石外露,用畜力犁拌
Shandong Taian highway section paving the road from Jinan to Changqing Highway grading, the use of tractor plow to draw multi-plow to mix graded material approach, the effect is very good. The specific approach will be introduced as follows: I. Overview The road is 17.2 kilometers long. It was originally a gravel road at the bottom of fist stone. It was lost in conservation due to its age. After the design for the graded gravel and natural gravel pavement, the road thickness of 5 to 12 cm, 3.5 km wide lane, subgrade wide 7.5 to 9 meters. Because of the old boxing stone in the design is still doing the bottom, so in front of the pavement with 12 tons of roller compaction is still difficult to flatten, there are still exposed fist stone, animal husbandry Plow
