近年来山西高速公路和国省道干线路网已初步形成,目前有多条公路已进入了正常的大修期,有些公路已成为老龄路、超龄路。特别是晋中国省干线公路承担着晋煤外运的主要任务,交通流量大,重载车辆多,对道路的损坏也较为严重。但多年来,山西省公路大修时存在设计方案简单,大修工艺传统落后,施工成本高等不足。为此,选择合理、科学的大修方案和推广新型工艺技术已成为目前山西省公路部门的迫切需要。
In recent years, the Shanxi Provincial Highway and the provincial trunk road network have taken shape. There are several highways that have entered the normal overhaul period and some of the roads have become the over-aged roads and the over-aged roads. In particular, the provincial highway of Shanxi Province of China undertakes the major tasks of coal transportation outside of Shanxi. Large traffic flow, heavy vehicles and heavy damage to the road are also serious. However, over the years, there are some problems in the highway overhaul in Shanxi Province, such as the simple design scheme, the backward tradition of overhauling technology and the high construction cost. To this end, the choice of reasonable and scientific overhaul program and the promotion of new technology has become the urgent need of the highway department in Shanxi Province.
