Evaluation of Skid Resistance of Grooved Pavements
Skid resistance is a critical factor for road safety, particularly in adverse weather conditions, as it directly impacts a vehicle's braking and maneuvering abilities. Grooved pavements have been employed to enhance skid resistance on highways and airport runways. However, over time, wear and tear can reduce their effectiveness. Therefore, continuous monitoring of the skid resistance performance of grooved road surfaces is essential. Unfortunately, there is currently no specific standard method for testing the skid resistance performance of grooved road surfaces. In this study, different groove patterns and specimen types were initially evaluated using the British Pendulum Tester (BPT). Subsequently, BPT simulation models and skid resistance simulation models were employed to calculate the actual skid resistance performance of grooved road surfaces. The results indicate that when BPT testing angles exceed 40°, the BPT test results tend to overestimate the road surface's skid resistance. This paper introduces a correction procedure to adjust the BPN values of grooved road surfaces, providing a robust theoretical framework for the practical implementation of BPT in monitoring the deterioration in skid resistance performance of grooved pavement surfaces.
