Role of Aggregate Characteristics to Load in SMA
Stone matrix asphalt (SMA) mixtures rely on stone-on-stone contacts among particles to resist applied forces and permanent deformation. Aggregates in SMA should resist degradation (fracture and abrasion) under high stresses ...
Role of Aggregate Characteristics in Resistance to Load in SMA
(International Center for Aggregates Research, 2006)
Stone Matrix Asphalt (SMA) mixtures rely on stone-on-stone contacts among particles to resist applied forces, and permanent deformation. Aggregates in SMA should resist degradation (fracture and abrasion) under high stresses ...
Evaluation of Superpave Fine Aggregate Angularity Specification
The validity of the Superpave fine aggregate angularity (FAA) requirement is questioned by both the owner agencies and the paving and aggregate industries. The FAA test is based on the assumption that more fractured faces ...
Effects of Superpave restricted zone on permanent deformation
The purpose of this study is to evaluate the restricted zone effect using four different aggregates: crushed granite, crushed limestone, crushed river gravel, and a mixture of crushed river gravel as coarse aggregate with ...
Effects of Aggregate Gradation and Angularity on VMA and Rutting Resistance
The Superpave system adopted the voids in mineral aggregate (VMA) criteria developed by McLeod using the 75-blow Marshall compactor for conventional dense-graded hot mix asphalt (HMA) mixtures. This VMA criteria is a ...
