Anti-skid property analysis of asphalt runway

In order to improve the anti-skid property of asphalt runway, ensure the take-off and landing safety of airplane, the anti-skid demand of asphalt runway was analyzed, its friction coefficient, roughness and durability were studied, the criterion of international civil and the anti-skid criterion of asphalt pavement in China were considered, the technical parameters of the pavement were put forward to ensure take-off and landing safety, and the influences of material character, the types, gradations and asphalt contents of asphalt mixtures on the anti-skid property were studied.Analysis result shows that the take-off and landing of airplane are safe when the friction coefficient is 45 measured by using portable pendulum tester, and the texture depth is more than 0.4 mm; rigider broken stone is taken as aggregate, stone matrix asphalt mixture is taken as pavement material, design gradient is rational, pavement firn is cleaned in time, etc, which may improve the anti-skid property of asphalt runway.
