Asphalt Concrete Pavement Construction Technology And Fleet Collaboration

In favor of 863 state program group intellectual construction machinery, aimed at asphalt concrete road surface technique and important equipment which plays an important role in national fundamental construction economy, the factors of influencing road surface quality in asphalt concrete construction and the optimized matching and coordination control in each step loop are studied in three aspects, construction technology, group machinery scanning and coordination, and paving intellectual control. The following conclusion can be got from the dissertation.(1) The problems in traditional asphalt surface construction technology within and outside of the country are analyzed and studied. The "transferring-paving" technique pattern has been brought forward firstly in our country through technique conformity around pavers.(2) The system optimized configuration method for quality, cost, construction efficiency and proportion of the construction resource has been put forward following the research of operation disciplinarian of the single machine in asphalt concrete road surface machinery group.(3) Based on queue theory, construction machinery technique control model of the asphalt concrete surface has been build to provide a base for group machinery coordination.(4) Due to the situation of asphalt surface construction, the intellectual group machinery communication project, based on the integration of wireless local network, wireless digital broadcasting station and GPS, has be en presented.(5) The system framework of cooperating work and optimized coordination of the asphalt concrete surface construction has been set up. The intellectual construction machinery group in the set framework breaks through the restriction of the original model, which will improve the mechanization level of the asphalt concrete surface construction.(6) Using CAN bus technique, fuzzy control theory and fuzzy inference mechanism in the control of the pavers, the hardware and software integrated system of the intellectual controlling and scanning has been formed to provide valuable experience for the design of the control system of the other construction machinery.(7) Through the assessing of the " transferr ng-paving" technique in great construction, spot inspect shows that the machinery group working pattern studied in the dissertation can enhance the construction quality of the asphalt surface effectively.Based on the sufficient investigation of the asphalt road surface in our country, the dissertation has studied the construction technique of the asphalt road surface and mechanical working pattern, the result of which has got the agreement of the highway construction company. The popularization of the new technique will produce an important influence in the highway construction and will promote the development of the construction machinery technology in our country.
