At present, the national standard stipulates that the initial retro reflective white line shall not be lower than 150mcd.m-2.lx-1, the yellow line shall not be lower than 100mcd.m-2.lx-1, the continuous retro reflective white line shall not be lower than 80mcd.m-2.lx-1, and the yellow line shall not be lower than 50mcd.m-2.lx-1. At the same time, it is proposed that the road marking shall have reflective performance in rainy night or wet state. However, the actual situation is that the continuous retroreflection of the markings is far below the standard requirements, and most of the markings do not reflect light in rainy night or wet state.

Two component road marking machine is to solve the above problems. Two component high brightness marking is not only suitable for new pavement, but also can realize "one spray and one light" for old marking in highway maintenance, which is a new product of rapid maintenance. In addition, the two-component highlight marking can also realize the reflection in rainy night or wet state, which improves the reflection of road marking to a new standard and realizes the maximum role of road marking in safe driving.
