Macrotexture plays a critical role in the tire-road interaction as it affects skid resistance, tire-pavement noise, rolling resistance and splash and spray. Thus, its measurement and/or estimation based on the properties of the pavement surface layer is important for highway engineers. The purpose of this paper is to illustrate the existing prediction models of macrotexture based on bituminous mix properties. In the technical literature several prediction models of macrotexture, depending on bituminous mixture volumetric and grading properties have been proposed. However none of them appears to provide satisfactory results because of low sample size or poor agreement with experimental data. Extensive data collection and new analysis are recommended to develop more effective and efficient macrotexture prediction models.

Abstract
Macrotexture plays a critical role in the tire-road interaction as it affects skid resistance, tire-pavement noise, rolling resistance and splash and spray. Thus, its measurement and/or estimation based on the properties of the pavement surface layer is important for highway engineers. The purpose of this paper is to illustrate the existing prediction models of macrotexture based on bituminous mix properties. In the technical literature several prediction models of macrotexture, depending on bituminous mixture volumetric and grading properties have been proposed. However none of them appears to provide satisfactory results because of low sample size or poor agreement with experimental data. Extensive data collection and new analysis are recommended to develop more effective and efficient macrotexture prediction models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
