Relationship of Aggregate Texture to Asphalt Pavement

Aggregate properties are one of the important factors that influence the asphalt pavement skid resistance. This study presents a detailed analysis of aggregate texture and its relationship to pavement skid resistance. A new method is developed for the evaluation of aggregate resistance to polishing.

Effect of Aggregate Characteristics on Texture and Skid ...

The skid resistance of asphalt concrete is highly influenced by the microtexture and macrotexture of pavement surface. It is believed that the microtexture and macrotexture are affected by the surface texture of pavement, which refers to the arrangement of aggregates and their aggregates characteristics.

Effects of Aggregate Size, Shape, and Surface Texture on ...

In summary, the maximum size of aggregate is important with regard to the skid resistance of the pavement, the percentage asphalt needed in the mixture, and the work-ability and economy of the mixture. Aggregate gradation and size range influence the strength and stiffness characteristics of the mixture, permeability, asphalt content, economy, workability, and skid resistance.

Prediction of surface texture for better performance of ...

2020-1-10  In order to promote an optimised asphalt mixture design, it is crucial to understand and quantify the effects of mix design parameters (e.g., aggregate percentages) on surface texture. Several studies have been conducted to study the effects of pavement texture and porosity on tyre-pavement interaction noise.
