Construction technology of colored asphalt mixture is similar to that of common asphalt mixture, and attention should be paid to the following:
1. Clean the original feed pipeline of black asphalt and dock the equipment of colored asphalt .
2. Before mixing, mixing tank in the mixing station is washed with hot aggregate several times cleanly.
3. Property of raw material should be stable so that mix proportion of production target can be close to that of design target greatly.
4. Temperature of aggregate is controlled at 170℃-190℃, and heating temperature of asphalt is at 160℃-175℃.
5. Pigment is packed in bag. Pre-calculate the amount of pigment for a jar of mixture before using and open package in advance. After aggregate is put into mixing tank, pigment is added directly. The suggested mixing time is 60s, and actual mixing time depends on the requirements of appearance for asphalt. Asphalt mixture should have performances of even coverage, no gray particl
