Machines' Deploying Of Asphalt Concrete Road Surface On West Tableland Area

The climate of west tableland is so scurviness that mechanized construction of highway project is hard and complex. The productivities of machines which are drived by diesel engines are affected greatly on the area because of the atmospheric change. The machines'number and deploying of the whole construction system are different between tableland and plain because of the decline of each machines'productivity. Using the constructing method of plain brings about the maladjustment of machine deploying and elevation of construction cost. The paper has great practical meaning to highway construction and construction enterprises while study productivity's descending law of each machine and machines'deploying on west tableland area.The paper summarize the construction relying on the selecting manual of highway construction equipments which is generation of the item of scientific traffic construction on west tableland area(item serial number:2001 318 223 83)and select the asphalt concrete road surface mechanized construction system as study object where the machines'kind is more, the quality of matching is more strong and using is extensive. more consider infection of air temperature and oxygenous content on the base of selecting manual of highway construction equipments, analyze and demonstrate by the numbers the productivity's reduced commonly law of different construction machines in different altitude. The paper combine and match different machines by the numbers from environment adaptability, working ability, reliability, economy nature, organizing management level, discretion, making the system move relatively more stable, efficiency higher, cost lower under the premise of adapting construction environment and satisfying constructing demand and bring forward machines'deploying using table in different altitude aiming at asphalt concrete road surface machines of mechanized construction in common use at present.
