Skid Resistance and Traffic Volume Characteristics of Some Selected Roads in Ado Ekiti, Nigeria

Abstract: Flexible pavements, commonly used for highways and airport runways, are prone to skidding accidents due to various factors such as surface texture, friction, and vehicle speed. Skid resistance is a critical parameter influencing road safety, as it affects the braking performance of vehicles, particularly in adverse weather conditions. The increasing number of vehicular accidents attributed to inadequate skid resistance highlights the need for a comprehensive understanding of the factors influencing skid resistance on flexible pavements. Using some selected roads in Ado-Ekiti, Nigeria, this study evaluates the frictional characteristics of road pavements. The frictional characteristic was evaluated by measuring the skid resistance of the road surfaces and relating the effects of the macro-texture (Texture Depth) and the temperature to skid resistance for wet and dry conditions. British Pendulum Test and Sand Patch Test were performed to account for micro and macro texture of the road sections respectively while glass thermometer was used to measure the temperature of the road surfaces. In addition, automated traffic counters were employed to measure traffic volume. Data from several roads were collected and analysed to evaluate the surface friction characteristics and how these were related to the volume of traffic these roads accommodated. Findings indicate variability in skid resistance across different roads, suggesting the need for targeted maintenance to enhance road safety. In addition, high traffic volumes on certain roads correlate with reduced skid resistance, possibly due to wear and tear. The research provides actionable insights for road management authorities to prioritize road maintenance and implement safety measures. The findings also underscore the importance of regular monitoring of road conditions and traffic volumes to ensure the safety and efficiency of the transportation infrastructure in the area.
