Abstract:Based on the field sampling and laboratory test, the effects of milling planer method on composition and performance of RAP are analyzed, and the effects of milling planer speed and crushing processing on gradation composition of RAP are analyzed. The result shows that layered milling planer recovery can obviously reduce the composition variability of RAP, the milling planer speed should be controlled in 6~8 m/min and the crushing processing technology is helpful to enhance the regeneration utilization ratio of RAP.
