HOW TO USE TIRE CHIPS AS INSULATION FOR GRAVEL ROADS

The U.S. Army Corps of Engineers conducted a full-scale field trial using tire chips as an insulating layer beneath a gravel surfaced road. The test road was constructed in Richmond, Maine. The field trial was designed to answer three primary questions: (1) the thickness of tire chips that are needed to provide adequate insulation; (2) the thickness of gravel cover that is needed over the tire chips to provide a stable riding surface; and (3) the effect tire chips have on ground water quality. To answer these questions several thicknesses of the tire chip layer and overlying soil cover were used. An extensive instrumentation and monitoring program was established including: thermocouples and resistivity gages to monitor thermal behavior; measuring surface deflections of the road with a heavy weight deflectometer; and monitoring ground water quality in several monitoring wells.
