Research on Comprehensive Evaluation Index of Pavement Anti-skidding Based on Variable Weight Model Method
A new method for evaluating pavement anti-skidding performance is proposed to address the limitations of a single evaluation index and a constant weight evaluation method,which cannot accurately reflect the level of road surface skid resistance,resulting in delayed maintenance and safety issues.Based on the"penalty incentive"variable weight model,this method comprehensively considers multiple evaluation indicators such as sideway force coeffi-cient(SFC),texture depth(TD),and pendulum British pendulum number(BPN).The dynamic weights is calculate by the penalty incentive variable weight principle.The constant weight evaluation method is optimized.And a com-prehensive evaluation index for road anti-skid performance is established,which is based on the variable weight model method that integrates multiple evaluation indicators.Taking the TJ01 section of the Lin'an Jiande section of the Linjin Expressway as an example,a comprehensive evaluation is conducted.The obtained results are compared with the actual situation.The results show that the variable weight comprehensive evaluation is feasible and more in line with the actual road surface anti-skidding situation.
