彩色路面的设置和作用

The setting and function of color pavement

贵州彩色沥青小编认为探究彩色路面有效减少交通事故的原理，一是，通过在铺装材料中加入耐磨的颗粒材料，使硬质骨材表面形成凸起，有效增加了彩色路面的防滑系数。

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.

根据试验，普通路面潮湿状态下防滑阻力为45（bpn值），彩色路面新铺装后潮湿状态下防滑阻力为78（bpn值），车辆磨损后潮湿状态下防滑阻力仍可达到76（bpn值）。从试验数据可见，彩色路面的防滑阻力比普通路面提高了68%。二是，彩色路面铺装是在原路面上形成5mm的凸起面层，使车辆通过瞬间产生轻快震动，提醒驾驶员需减速度行驶。三是，通过色彩与路面颜色形成强烈反差，给驾驶员在视觉上造成冲击，从而达到提高驾驶员注意力，采取有效措施减速慢行的效果。

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.
