Strength characteristics of crushed gravel and

As for the aggregate materials, crushed limestone and crushed gravel, commonly used in Illinois in base/subbase applications, were considered. Illinois dense graded base specifications allow aggregate materials with a maximum particle size of 25 mm for the CA 6 specification and 50 mm maximum particle size for the CA 2 aggregate.

Strength characteristics of crushed gravel and

Higher strength values were obtained for the CA 6 aggregates with 25-mm maximum particle size compared to the aggregates tested for CA 2 specification. Considering typical property ranges, a dust ratio of 1.0 was found to be a viable option in some cases for base/subbase applications providing an acceptable soaked strength for both crushed limestone and crushed gravel.

Effect of Limestone and Inorganic Processing

The Illinois Department of Transportation (IDOT) is making several changes to concrete mix designs, using revisions to cement specification ASTM C150 / AASHTO M85 and ASTM C465 / AASHTO M327. These proposed revisions will enable the use of more sustainable materials for concrete pavements, overlays, and bridge decks. Accordingly, a study was conducted by the University of Illinois at Chicago
