Application Research On Rubber Asphaltic Concrete Technology Of Pavement Construction In Jinan

The rubber asphalt, can not only improve the asphalt high to low temperature performance, ways to improve traffic hob-nailed pit-boots deterioration of road safety and road use life, and the rubber tire, recycling and protecting the environment. therefore, the contribution of rubber tires. The research and apply a bituminous material used and the road has been getting attention. Science and technology workersThis reference to previous research achievements and material, on the basis of the following four aspects of the research content:First, the technical theory analysis ARC, through the dry mixing process and wet process of asphalt mixing rubber powder, determine the mixture of structure and technical indexes of rubber asphalt concrete, and use of property and mechanical performance analysis, for practical use theory and provide technical feasibility analysis.Secondly, researching ARHM proportioning design, in ARHM design principles and standards, under the guidance of the target of rubber asphalt concrete mixing proportion and production were studied。Again, dry mixing rubber asphalt concrete test method is studied, Through a series of experiments provide standard, principle of mix design, determine the dry mix method rubber asphalt mixture ratio of powder content and mix proportion design,then determine the dry mix method rubber asphalt pavement.This construction technology and construction quality control.Finally, the rubber asphalt concrete mixing wet method of experiment research, Certain proportion of blending of rubber asphalt rubber, To apply, asphalt content test to determine the appropriate proportion, and dry mixing method rubber asphalt pavement.this construction technology and construction quality control.The text by using information and research results from pitch concrete role of the mechanism of rubber or use of performance, have the change, in-depth rubber a mixture of asphalt the importance of performance, and made some valuable data, the filter out the rubber powder the asphalt with the best and quantity. On this basis, with a mixture of asphalt the performance indicators for detection, the result is that a rubber tire, add the flour and the bitumen and bituminous modified, stability, sensitivity high temperature and low temperature to such indicators than they are not add a distinct and, for research purposes. Based on the test of the final road paving, sums up the Jinan area highway construction of asphalt pavement construction craft, rubber for road construction has accumulated experience. Research result shows that the two processes, each have each has its advantages and adaptability.Such as national 220 line ChenZhuang to bear mountain in tuen mun reconstruction project is the important way to jinan changqing, dongying, binzhou is connected, jinan, taian, heze city road auges, etc. With the increase of road use fixed number of year, after a long period of traffic load, subgrade pavement appeared different degree of disease, In 2008, the dry mix method do outside mixing rubber powder consummates, so far no rut, cracks, etc. But ordinary SMA - 13 asphalt concrete pavements in crossing location, traffic lights position substantially track, comparative effect is obvious, but still further observation and experiment.Such as national 220 line ChenZhuang to bear mountain in tuen mun reconstruction project is the important way to jinan changqing, dongying, binzhou is connected, jinan, taian, heze city road auges, etc. With the increase of road use fixed number of year, after a long period of traffic load, subgrade pavement appeared different degree of disease, In 2008, the dry mix method do outside mixing rubber powder consummates, so far no rut, cracks, etc. But ordinary SMA - 13 asphalt concrete pavements in crossing location, traffic lights position substantially track, comparative effect is obvious, but still further observation and experiment.Dry mixture of asphalt by rubber and wet mix the two specific projects and further instance of the rubber a mixture of asphalt with the design and construction processes and construction quality control technology, and for rubber asphaltic concrete high to low temperature performance for observation and comparison with a view to collect more data and accumulating experience, for its part in the construction of Jinan the application or instruction. to provide.
