AASHTO PP 64-11 (2017) PDF Download

AASHTO PP 64-11 (2017) provides guidelines for the determination of aggregate source shape characteristics using digital image analysis. The objective of this standard is to assess the shape properties of aggregates, such as angularity, texture, and form, which can influence the performance of aggregates in various construction applications.

The standard outlines the procedure for conducting digital image analysis to obtain shape properties of aggregates. This involves capturing high-resolution images of the aggregates using a digital camera or scanner and analyzing these images using specialized software. The software measures various shape properties, including size, elongation, flatness, roundness, and texture, which are important indicators of aggregate quality.

By following the guidelines outlined in AASHTO PP 64-11, engineers and researchers can obtain accurate and consistent shape values for aggregates from different sources. This information can be used to assess the suitability of aggregates for specific applications, such as concrete production, asphalt mix design, and road construction. It enables better understanding of how different aggregates behave and perform under different conditions, ultimately leading to more precise and effective material selection in construction projects.
