Investigation of Rutting in Asphalt Concrete Pavements

2018-4-4 · deformation (ruitlng) in asphalt concrete pavements is the characteristics of the aggregate. Rut-resistant mixtures are composed of large maximum size, crushed aggregate with little or no natural aggregate (sand and/or gravel). The gradation is designed to provide stone to stone contact to.

Selecting the correct materials | Asphalt magazine

Aggregate types are natural or uncrushed (smooth and round)—or crushed with single or multiple crushed faces. Rough textured, crushed and angular aggregate is needed to carry heavy loads without rutting or deformation. Particle size and surface texture also change the workability, strength characteristics and compactability of an asphalt mix.
