Maintenance Of Asphalt Road In Mountainous Area Of GUIZHOU Province Technology Research

As of 2017,the main route of GUIZHOU province has reached 2.62 million kilometers,covering 1,241 townships,covering 80.2 percent of the total.Among them,the normal state road reached the second level and the above proportion was 58%,the ordinary provincial road reached the third level and the above proportion was 31%.Large-scale mountain area highway construction solves the GUIZHOU people travel and the development of regional economy in GUIZHOU,barrier allows,without rewritten for thousands of years in GUIZHOU,the three mile flat geomorphic characteristics;Indirectly,the economy of GUIZHOU has been growing rapidly,breaking the tradition that GUIZHOU people have no three points of silver.With the rapid development of highway construction in the mountainous area of GUIZHOU province,the heavy highway maintenance work has been followed,and scientific and reasonable highway maintenance management is of great importance.In GUIZHOU mountain area highway to a certain extent,it is a typical representative of the south China karst mountain area highway,but due to the mountainous area highway typical karst landform,and agitation,plateau rainy climate extremes,overloaded personality traits,such as mining area in GUIZHOU mountainous area highway asphalt roadbed diseases and these diseases seriously affected the normal use of GUIZHOU mountainous area highway,also greatly reduce the service life of the mountainous area highway.Therefore,this paper is based on the systematic study of the disease treatment technology of the asphalt road of mountain road by ANSHUN road bureau of GUIZHOU province.For GUIZHOU ANSHUN the kingdom of the jurisdiction of the highway section of the actual situation of provincial trunk in ANSHUN area the provincial trunk line,the asphalt pavement structure,the disease characteristics,curing treatment technology has carried on the detailed investigation and summarized.On this basis,summarized in GUIZHOU mountainous area highway asphalt pavement disease causes,analysis the current GUIZHOU mountainous area highway using traditional typical maintenance treatment technology,summarizes the advantages and disadvantages of various curing technology,put forward suitable mountain asphalt roadbed part maintenance method.At the same time,the applicability of various maintenance technologies in GUIZHOU mountain roads is verified by physical engineering,and the construction points of various maintenance technologies are analyzed.The contents of daily minor maintenance are further studied.According to the unique geography and climate conditions in GUIZHOU,GUIZHOU highway system based maintenance management mode,in view of the mountainous area in GUIZHOU highway asphalt roadbed minor repair and maintenance technology and DaZhongXiu maintenance technology is analyzed,and actively explore and attempt to the improvement of maintenance technology,the research in geography,climate and technical conditions in GUIZHOU mountainous area highway asphalt pavement maintenance technology,using local materials,saving the maintenance cost,the principle of protecting the environment,guiding GUIZHOU mountainous area highway asphalt pavement maintenance,to GUIZHOU mountainous area highway maintenance business,promote social and economic development in GUIZHOU.
