MODELING PAVEMENT TEXTURE DETERIORATION AS A PAVEMENT PRESERVATION MANAGEMENT SYSTEM TOOL

摘要

This paper examines the change of pavement surface treatment microtexture and macrotexture over time,and presents deterioration models for six commonly used pavement preservation treatments. The data for the modelswas developed from a 3-year field trial that exposed all six treatments to the same traffic and environmentalconditions on an identical substrate. Monthly measurements of microtexture and macrotexture were taken during thetest. The paper concludes that the resultant deterioration models can be used to incorporate safety criteria, i.e.surface texture, in existing pavement management systems to enhance roadway network safety.
