    Abstract

    Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. Texture influences many aspects of road safety and comfort, including friction, smoothness, splash and spray, rolling resistance, and numerous others. The focus of this paper is on techniques to measure and analyze texture, particularly that which influences tire-pavement noise and friction. Standards for characterizing texture geometrically are described, and techniques that describe texture in terms of its influence on functional performance are explored.

    Keywords:

    pavement, texture, profile, tire-pavement noise, friction, smoothness, splash and spray, rolling resistance
