PowerPoint Presentation - Aggregate Imaging Measurement System (AIMS)
Slide 1 – Aggregate Imaging Measurement System (AIMS)
Project Team: Pine Instrument, Texas A&M, and Texas DOT
A video-clip is available (.wmv, 14.5 mb)
Slide 2 – Need
- Aggregate shape properties have been shown to be related to the structural integrity and performance of pavement systems.
- Existing tests for aggregate shape properties are time-consuming and subjective.
Anticipated advantages over conventional practice
- Enhanced information on the aggregate material shape properties will help improve pavement performance and augment predictive models.
- AIMS provides objective, repeatable, and rapid measurement of aggregate shape properties.
Slide 3 – AIMS Characterizes Aggregate Shape Properties for Pavement Materials
Slide 4 – Existing Technique
Under ASTM D5821, aggregates are examined manually and fractured faces are counted on each particle
Captures and analyzes images of multiple particles and characterizes the material sample. A graphical output is provided.
