Characterization of Open-Graded Aggregates
Project Information
This project will characterize natural aggregates based on the American Association of State Highway and Transportation Officials (AASHTO) Designation: M43-05; and the ASTM International Designation:
D 448-03a. State departments of transportation (DOTs) and counties use this designation (or an equivalent) to specify the aggregates used in the construction and maintenance of highways and bridges (e.g., the geosynthetic reinforced soil integrated bridge system).
Goals
The objectives of this research are:
(1) Provide engineers with the strength properties of the common AASHTO open-graded aggregates used in construction.
(2) Describe the influence of saturation, angularity, and source on the strength.
