Recycled Asphalt Road Machine
The heat drum of RAP: The patent design (patent no. ZL200810189181.1) of elastic paddles solves the problem of RAP sticking with drum and paddle during heating. There are also several paddles with hook to collect large size of RAP from the RAP and make them roll and fall in the drum with better heat effect. Thus, the heating of coarse/fine RAP is well managed to reduce the temperature difference of fine RAP after heating and prevent the bitumen-aging of fine RAP due to over-temperature.
