Abstract. 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...
Abstract. Transportation agencies need performance indicators to report the pavement condition. Many local transportation agencies use the Pavement Condition Index (PCI) to report the pavement condition. In 1986, the World Bank developed the International Roughness Index (IRI) to measure the irregularity of the road surface. IRI is an indicator of roughness for straight horizontal road...
Abstract. Grip, or skid-resistance, is a fundamental attribute of a racetrack and needs to be understood by track owners, operators and racing teams. An analysis of racetrack wet grip produced datasets comprising tens of thousands of geolocated data points. The aim of this paper is to demonstrate that the datasets can be used to create Triangular Irregular Networks (TINs) that present grip...
Abstract. The paper presents a system aiming at characterizing water spray induced by a tire rolling on a wet road and relating it to the water depth on the road surface. Water splash and spray mechanisms are briefly reminded and definition of water depths are given. The system setup, composed of ac-celerometers to record vibrations of the front wheel arch liner, is described. Tests are...
Abstract. Transportation Safety continues to evolve as a significant area of interest and concern. As a result, evaluation of safety from a pavement surface characteristics perspective is also attracting additional interest. Historically, pavement safety assessments have focused on discrete, low density friction assessments with common technology not changing much in the past half century -...
Abstract. Sealing or filling cracks in pavement surfaces has been a common pavement maintenance technique adopted by many agencies. Mastic has been a common material implemented in these activities due to its flexibility, adhesion, and strength properties. In cold regions, the presence of freeze and thaw cycles contributes to the generation of severe transverse cracks that impact ride quality....
