Rural Road Maintenance Technology Program Research And Application

In recent years, our country pays great attention to rural road's construction, increases investment, strengthens management and has made great achievements, The highway mileage is increasing and access degree is improving. However, the rural road's structure is not perfect, the technical level is low and the overall level of development is not high. They can not meet the needs of rural economic development. Especially in the rural road's maintenance and management the number of professional and technical people and managerial staffs are inadequate. Therefore, the maintenance and management of rural roads should combine with the actual situation, formulate a practical method to maintain and manage the rural roads, improve the level of the rural road's maintenance and management and ensure the smooth of the rural roads, The research and application of the rural road's maintenance program is a new subject for us but also a subject responds to the national policy and adapts to the development of the rural economy.First, the article describes the common damage types of the rural road and classifies the rural road's maintenance systematically. Besides, it also introduces the present research condition of domestic and foreign countries.Secondly, the article analyzes the causes of the rural road's damage and takes the asphalt road and cement road for example to analyze the common causes of rural road's damage.Then,this paper describes the practical techniques of rural road's maintenance and takes the asphalt road and cement road for example to describe the practical techniques of rural road's maintenance.Finally, it takes part of the rural road's maintenance in Dacao,Ningjin for example to investigate the disease type of the pavement, analyze the reasons of the road's damage, select reasonable maintenance techniques and evaluate the effectiveness of the maintenance.
