[0003] At present, the quality of colored pavement construction technology is poor, and it is easy to fall off, peel, crack and other phenomena, which cannot achieve the expected effect. The manufacturing cost is relatively high, and the shock absorption and protection effect of the pavement is poor. When a fully loaded or even overloaded truck is driving, it will be subjected to a large external force impact, which can easily cause the pavement to crack. The service life of the pavement is very short and requires frequent maintenance. During maintenance, structures such as isolation barriers are needed to guide traffic, which will occupy a large area of ​​the pavement, so it will also have a certain impact on traffic.
