Study On Rural Road Pavement Structure In Jiangjin District

At present,there are several typical problems in the construction of rural roads in jiangjin district.Firstly,the technical grade of the highway is generally not high;Second,the road network construction is slow,some rural roads have not been connected with the main road network;Third,the width of the road is generally insufficient and the driving conditions are poor.Fourth,there is still no mature road technical control index applicable to jiangjin area.Based on the above situation,the paper through the study and formulate suitable for the road indicators of metro area,this paper set up technical indicators including the typical pavement structure,construction materials,such as quality control index.Paper selected topic,the author first surveyed the metro area of rural highway traffic,a collection of subgrade width,including its structure,material,information,such as traffic participants and do a lot of analysis,in order to be able to use the method of typical model were studied.The metro area road after some understanding basic situation,in this paper,the rural road traffic participants metro and other traffic characteristics are summarized and analyzed,and on this basis to differentiate the traffic of different grades,conform to the requirements of the design parameters.Finally,according to the practical geological situation of the metro area,natural conditions and design parameters of subgrade and how to determine the actual construction of subgrade dry humidity control,rural roads roadbed and the metro area divides the level to represent the actual strength of roadbed.In addition to the above theory research,this article also is commonly used in the rural road construction of metro materials did some research,and on the basis on the material selection and the parameters of the roadbed design discussed some,and draw lessons from some local roads summed up the experience,in the process of common structure analysis of local concrete and asphalt roadbed.And how to control the construction process,ensure the construction quality of the theoretical research.Theory research of this paper is based on the reality of rural road,metro considering the roadbed feature and construction materials,etc.,supplemented by construction quality control theory,have a certain practical significance,can to a certain extent,reduce the cost,has a certain universal significance.If it can be applied gradually in the rural road construction in jiangjin district,it can greatly improve the local road condition and make the local rural roads have a higher service life with lower cost.
