1955年5月从前,广东省海康工区42道班还是一个很落后的道班。那时,这个道班所养护的路段,雨天满路泥泞,晴天灰尘迷目,行车时速仅达15～20公里。现在,42道班已经走进了先进的行列,他们养护的路段都铺上了磨耗层,行车时速提高到40～50公里。 42道班是怎样提高路面质量的呢?他们主要抓住了下面几个环节: 一、重视材料的选择和配合重视材料的选择和配合是延长磨耗层维修期、提高路面质量的先决条件。过去42道班在铺筑磨耗层时,为了贪多图快,所用材料都是
In 1955 May before, Guangdong Province, Haikang 42 work area is still a very backward road classes. At that time, the road section of conservation section of the road full of muddy days, sunny dust cats and dogs, driving only 15 to 20 kilometers per hour. Now, 42 classes have entered the advanced ranks, and the sections they maintain are covered with wear layers, driving speeds of 40 to 50 kilometers per hour. 42 road how to improve the quality of the road? They mainly seize the following aspects: First, attention to the choice of materials and attention to the choice of materials and cooperation is to extend the wear layer maintenance period, improve the quality of the road prerequisite. The past 42 classes in the wear layer, in order to greedy more quickly, the materials used are
