上海11选5The setting and function of color pavement
Guizhou color asphalt Xiaobian that explore color pavement effectively reduce traffic accidents is a principle, and through the particle material to wear in paving material, which are formed of hard aggregate surface, effectively increase the coefficient of friction of color pavement.
According to the test, the slip resistance of the pavement under wet condition is 45 (BPN), and the anti slip resistance of the wet pavement is 78 (BPN value) after the new pavement. After the vehicle wears, the anti-skid resistance of the pavement can reach 76 (BPN). It can be seen from the test data that the anti skid resistance of the color pavement is 68% higher than that of the ordinary pavement. Two, the color pavement is to form the 5mm raised surface on the original road surface, so that the vehicle can vibrate quickly through the instant, and remind the driver to drive at a reduced speed. The three is to form a strong contrast between color and the color of the road, which will impact the driver's vision, so as to improve the driver's attention and take effective measures to slow down.
