The Research And Application Of Cold Recycling Technology

The highway construction is a project that needs great money and lasts a long period. It hold the balance of civil economy and modern national defense, it ask for theory research and carry out manipulation of new material from the view of scientific and being practical and realistic to make use of limited financing to promoted highway construction.Pavement cold-in place recycling is a new technique of form pavement structure, it include three steps: the fist step is the processing of old asphalt pavement material including asphalt pavement and parts of road base material, then add some new bone-material or thin material to these material according to the characteristic of cold recycling structure, at the same time add some water and in addition matter according the quantity of material, at last deal with these material in environment condition to form an new structure.Based on the characteristic of cold recycling technology, its advantage is analyzed in this paper. The effect of different in-addition and dose of addition on material capability is interviewed by in-door experiment. The parameter value of feasible scope, resist-intention, resist-intention elastic module and crack intention is given out. Experiment result is tested through in-place examine of experiment road and analysis to correct and perfect the experiment conclusion, at the same time quality inspect and evaluate standard is summarized in this paper.At lasts the economy character of application of old asphalt concrete pavement in-place cold recycling technology given out in detail, it can be used to be the scientific base of pavement structure design, construct, and supervise of apply cold recycling technology. To sum up, the theory research and application of cold recycling technology will save lots of money, alleviate environment pollution and bring up unlimited economy and society benefit.
