Abstract

Friction in pavements is an especial phenomenon that varies upon many variables such as weather, pavement’s age, material properties, and tire-surface contact. Furthermore, it is a very important factor since it is related to safety. To measure friction there are different procedures and methodologies. Depending on the method, and even the equipment used to measure skid resistance, output data can vary. In addition, friction varies with time. Some studies state that friction has a decreasing linear behavior, and others say behavior dependents on temperature and the level of exposure of aggregates’ surface, so friction in pavements is a subject still on development and having consistent measurements of skid resistance is complicated. Based on the Long-Term Pavement Performance (LTPP) data base, this study found that friction can be related to the pavement condition index (PCI) and roughness (IRI). These findings can support alternative approaches to estimate skid resistance on a more suitable way and take proactive actions to maintain adequate safety ranges on roads.
