Paving of hot mix asphalt mixes with paver with automatic leveling device and automatic adjustment of paving thickness. The spread of the paver is matched with the production capacity and the volume of the mixer to ensure continuous paving of the mix.

Paving speed control in the 2 ~ 4m / min. The spreader of the paver should be adjusted to maintain a stable speed evenly with respect to the paving speed, and the mixers on both sides of the paver should be kept at a height of not less than 2/3 of the screw feeder Reduce the separation of the mixture during the paving process.
