English Abstract

Skid resistance is one of the major road pavement characteristics, which determines the friction between the road surface and vehicle tire.

Skid resistance is important to ensure sufficient road safety. Skid resistance plays very important role especially during wet and rainy conditions. This study aimed to identify the most important factors that effect on skid resistance to reduce the exposure of vehicles to traffic accidents caused by skid resistance especially in wet weather and to determine the management process to maintain a sufficient level of skid resistance pavement monitoring to reduce time and effort in laboratories tests and to improve rods safety. Thus, the factors that effect on skid resistance were selected and analyzed using SPSS software, the portable skid resistance tester; British pendulum skid tester was used to measure the surface texture. This research presents a review on the research studies that have been done on characterization of the frictional properties of the pavement surface and discussed methods used for measurement and evaluation of texture characteristics The factors that influence friction and the concepts of how friction is determined (based on measurements of surface micro-texture and macro texture) are discussed.

Number of different methods and devices, which are currently being used in practice to measure skid resistance both in the laboratories and in-situ in Jordan and outside Jordan was discussed.

Also, a discussion of how paving mixtures and type of aggregates can be selected to achieve the design friction level.

In this research skid resistance prediction models were performed, such models type of tire, pavement surface texture characteristics, vehicle speed and mixture type.

Methods for monitoring the friction of in-service pavements and determining appropriate actions in the case of friction deficiencies (friction management) are described.

This research examines how benefits can be accrued from the implementation of a fit-for-purpose local strategy to manage road surface skid resistance. The results of this study indicate that the management process models were applied to reduce time and effort and to quantify the impacts of these factors on skid resistance and applying skid resistance management process lead to improve Highway safety and reducing accidents, which in term reducing the rate of fatalities.
