EFFECTIVENESS OF GEOSYNTHETICS FOR ROADWAY CONSTRUCTION IN COLD REGIONS: RESULTS OF A MULTI-USE TEST SECTION

The Maine Department of Transportation has reconstructed a 3.0 km portion of U.S. Route 1A within the towns of Frankfort and Winterport, Maine. This roadway is plagued with poor subgrade soils (A-6) and has been historically known for its poor pavement performance. The reconstruction project is providing an excellent opportunity to evaluate the effectiveness of alternative pavement sections incorporating varying geosynthetics in different...
