Working Principle
The Friction Coefficient Tester is designed to evaluate pavement surface friction and skid resistance under controlled testing conditions. The system measures the lateral force generated between the test tire and pavement surface and calculates the corresponding friction coefficient.
The equipment is suitable for pavement condition assessment and friction performance evaluation of roads and airport runways. It can be equipped with an adjustable water spraying system to simulate wet pavement conditions and provide reliable test data for pavement safety assessment.
