为改善与提高泥结碎(砾)石路面的使用质量,我省于1964年开始利用道路渣油作路面表面处治。目前共修建了22.8公里,其中锦西厂渣油(C~5_(60)为30～60秒)修建了13.4么里,杭州厂渣油(C~5_(60)为6.8秒)修建了9.4公里。渣油路面处治层的矿料采用碎石及砾石,使用品质均良好。对渣油路面的养护,我省道班工人从养护泥结碎石路面转到养护渣油路面上来,开始没有经验,养护质量较差。我们照着主席思想做,不断实践,不断总结,目前已初步摸到养护渣油路面的方法,现介绍如下。
In order to improve and enhance the quality of the use of mud stone (gravel) stone pavement, our province in 1964 began to use road residue as pavement surface treatment. At present, a total of 22.8 kilometers have been built, of which 13.4 milliliters of residual residue from Jinshi Factory (30-60 seconds for C ~ 5_ (60)) and 9.4% for Hangzhou Plant Residue (6.8 seconds for C ~ 5-60) Km. Gravel road surface treatment layer of gravel and gravel, the use of good quality. The conservation of residual oil pavement, our provincial class shift workers from the maintenance of cement-bonded gravel road to the maintenance of residual oil pavement, began without experience, poor quality of care. We follow the thinking of the Chairman, continue to practice and continue to summarize. At present, we have initially touched on the methods of maintaining the residue surface and are described below.
