Hot In-Place Surface Recycling in asphalt Pavement

摘要

The present invention relates to the field surface heating Asphalt reproduction method, and more particularly on a damaged road cutting the heated surface and by laying a road as a mixture of virgin resin and an additive playing a waste asphalt mixture of asphalt mixtures produced by compaction, improving the quality of the packaging, as well as solve the environmental problems caused by waste asphalt mixture and to reduce the construction cost can be, sampling and analysis of the broken road by the steps of blending the reproduction design asphalt mixture (S1) and; And a step (S2) to the primary heat the surface of the broken road using a preheater; Step (S3) and for heating the preheated secondary road; And a step (S4) the second heating in the road to the cutting depth of the primary 2.5~3.0 ; And a step (S5) to inject a certain amount of play primary cutting additive in the waste and virgin asphalt mixture of asphalt mixture; The road surface and the first cutting step (S6) of the third heating; And a step (S7) of the secondary cutting the third road heated to a depth of 2.5~3.0 ; Second cutting lungs are the primary cutting asphalt mixture additive and play virgin asphalt mixture of asphalt mixtures are injected lung primary pug mill mixing step (S8), and; And a step (S9) of the first mixed in a mixer mixing the second mixture; Second Mixed Play laying the asphalt mixture, and comprising the steps (S10) to commit.
