Abstract
The frictional performance of aggregates is crucial in the skid resistance of asphalt mixtures. Conventional methods for quantifying aggregate frictional resistance by the process of sample preparation and polishing are time-consuming. This study investigates the potential of aggregate mineralogical (e.g., average hardness value (AHV) and contrast of hardness (COH)) and morphological parameters (e.g., angularity and texture) in estimating aggregate frictional performance. A total of twenty-eight aggregate sources from quarries in different locations within Texas were sampled and subjected to mineralogical and morphological evaluation using powder X-ray diffraction (XRD) and aggregate image measurement system (AIMS), respectively. The frictional performance was evaluated after polishing using a three-wheel polishing device with a dynamic friction tester device. The contributions of mineralogical and morphological parameters on aggregate frictional performance were assessed based on pairwise correlation and multiple linear regression analysis. The results indicate that aggregate frictional performance is controlled by AHV and COH and, to a lesser extent, by the angularity and texture of aggregates. The study suggests that powder XRD can be used as a faster alternative to conventional test methods for assessing aggregate frictional resistance.
期刊介绍:
Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged.
Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
