Laboratory Testing of Aggregates for Road and Bridge Construction

Project Information

Project ID: 
FHWA-PROJ-12-0039
Project Abstract: 

This project reviews existing documentation on direct shear testing of aggregates and the friction angles used in design of roads and bridges. For open and well graded AASTHO aggregates: (1) sieve analysis to verify AASHTO designation (ASTM C136-01) for the aggregates tested.

Goals

The primary objectives are:

(1) To compare strength results of American Association of State Highway and Transportation Officials (AASHTO) open-graded aggregates tested using large-scale direct shear.

(2) Investigate effect of relative density and scale on strength of open-graded aggregates.

(3) Quantify strength of AASHTO well-graded aggregates.
