Base Stabilization Additives - Effect on Granular Equivalency (GE)

Status:  Active
Project Start Date:  12/16/2019


In particular, determining granular equivalency (GE) factors for various proprietary geomaterial stabilizers will benefit Minnesota Department of Transportation (MnDOT) and county engineers by establishing design parameter values and a means for comparing additive effectiveness and cost. The proposed research has three main goals: (1) evaluate the performance of selected proprietary additives by conducting laboratory and field tests; (2) prepare pavement designs and construction specifications based on the test results; and (3) analyze the benefits of additives in terms of pavement construction cost savings and long-term service life.
