With the approach of winter, familiar signs begin popping up all through the whole extent of the northern climates. Wherever frost-susceptible soils mix with freezing water, road subsurfaces push upward, or "heave," moving boulder displacing road stakes and pushing by the and of pavement.

Engineers at the U Army icy Regions Research & Engineering Laboratories (CRREL) in Hanover, NH have establish that a layer of tire chips spread beneath the road surface will provide insulation that remodels frost penetration into the soil The process minimizes frost heave formation and gives a low-cost way to help clear the problem of discarded tires since it uses approximately 150000 tires for mile of road.

Robert Eaton, research civil engineer at CRREL and developer of the universal worked with Dana Humphrey, associate professor of civil and environmental engineering at the University of Maine, to standard the process during the last sum of two units winters. They divided a 750-foot extend ...
