Abstract: In recent years, colored asphalt pavement began to be widely used in China However the cost of existing road changed color is high, the maintenance of existing color pavement is difficult, which is the problem need to be solved Therefore, based on the previous research, the preparation of color emulsified asphalt and the micro-surface test was introduced in this paper The results showed that performance of the preparation of colored emulsified asphalt made by colored asphalt meet the relevant technical requirement of slow crack color emulsified asphalt of micro-surface with the content of 10% of emulsified asphalt, the mixture test results meet the requirements of micro-surface.
key words: colored pavement; colored asphalt; emulsified asphalt; micro surface
