One, on the surface of the wheel pressure car part is not covered by all when: part of the wheel in the road markings on the part of the wheel on the pavement, at this time, the emphasis is on the road markings and pavement anti-skid matching, although the national standard for Anti-skid road markings should not be less than 45, but the roads with the increase in life, the road itself is also changing the anti-skid value, so the new line, On the old road on the application of the Anti-skid value requirements are not the same, the emphasis on matching, rather than blindly pursue the high anti-skid value of the line.
Such markings generally include road lines, lane boundaries, arrows, text, etc. in this case, road markings should have the following characteristics:
1, daytime and night are clear to distinguish, in the night, rain and bad weather conditions, but also should have reflective, in high-speed driving can give the driver a certain amount of time to identify in advance. Appropriate whiteness, reflectivity and stain resistance (day and night visible)
2, should be good non-slip matching (non-slip)
3, should be good adhesion to the road surface, adequate weatherability, resistance to melt salt, and has effective wear resistance (durability)
4, on the road can not be too convex (film thickness)
5, must not cause road fissures, resulting in subgrade damage (cracks)
Generally speaking, the current road markings in dry and sunny weather, non-slip problem is not very large, but in the night and rainy days, non-slip performance is not ideal, this may be a traffic accident potential.
Second, the surface of the wheel pressure car part of the total coverage of the part that is: The wheel is all on the road markings such as the full spread of the color non-slip pavement, non-slip requirements should not be less than 65.
