Insulating and Load-Supporting Properties of Sulfur Foam for Expedient Roads in Cold Regions
Temperatures of the subgrade and of sulfur foam insulation test sections in an expedient road were monitored with thermocouples to document freezing and thawing conditions. Vehicular trafficking was conducted on a limited basis to determine the load supporting capabilities of the foam. The sulfur fo...
