Problems solved by technology
[0003] The steel slag asphalt concrete pavement needs to be tested for its various properties when it is used, including the detection of the anti-skid performance of the pavement. The existing part is tested by setting the car through the slope, etc., and the sliding distance of the test car is applied in reality in proportion In medium-sized vehicles, the anti-skid performance value of the detection has great uncertainty and low accuracy, and the vehicle bodies of different qualities and the changes in the slope of the road surface are different, so it is impossible to perform accurate calculations.

The invention discloses a method for testing the anti-skid performance of a steel slag asphalt concrete pavement. The method comprises the following steps: S1, manufacturing steel slag asphalt concrete pavement section and trolley slope adjustable test equipment and a recording device; and S2, recording a height value h of a scale corresponding to a comparison block. According to the method, the steel slag asphalt concrete pavement section and trolley slope adjustable test equipment and the recording device are arranged to measure a plurality of trolleys at the same time; a friction coefficient of the steel slag asphalt concrete pavement can be measured according to a physical formula; different heights can be adjusted for measurement and then an average value is calculated, so that the friction coefficient can be measured more accurately; the antiskid performance of the pavement can be determined by detecting the friction coefficient of the steel slag asphalt concrete pavement, and the braking distance of the vehicle quantity under different conditions can be detected more accurately according to the friction coefficient.
Description
technical field [0001] The invention specifically relates to a method for testing the antiskid performance of steel slag asphalt concrete pavement. Background technique [0002] According to the characteristics of steel slag, it is "passivated" and crushed in a special way to analyze its chemical composition and test its activity. Steel slag is an alkaline aggregate. Attachment performance is very good. After testing and optimizing the design ratio, the steel slag asphalt concrete with high splitting strength ratio, high residual stability and good rutting resistance has been developed. [0003] The steel slag asphalt concrete pavement needs to be tested for its various properties when it is used, including the detection of the anti-skid performance of the pavement. The existing part is tested by setting the car through the slope, etc., and the sliding distance of the test car is applied in reality in proportion In medium and medium-sized vehicles, the anti-skid performanc...
