AIMS: The Future in Rapid, Automated Aggregate Shape and Texture Measurement

The Aggregate Imaging System (AIMS) is an important development, which allows for rapid measurement of physical characteristics of aggregates. This advanced technology consists of a computerautomated video system that directly analyzes texture, angularity, and shape of aggregates. Laboratory testing of aggregate stockpiles was conducted at field paving projects in the Federal Highway Administration Mobile Asphalt Testing trailer. An investigation was performed to tie the various AIMS results to three of the four SuperpaveTM (Superpave) consensus properties: coarse aggregate angularity, fine aggregate angularity, and flatness and elongation. The results show that the overall ranking or trend between the AIMS results and Superpave consensus properties are similar. The AIMS was also used to measure properties of different types of aggregates collected at paving project sites such as granite, limestone, Reclaimed Asphalt Pavement (RAP), and gravel. The data was then examined to identify trends for angularity, texture, and shape among the different aggregate types. Data analysis indicated that the potential exists for establishing relationship between AIMS sphericity and Superpave consensus property flat and elongated values for coarse aggregates. Based on these findings, the AIMS may be a faster and more accurate replacement for certain Superpave consensus property tests.
