Abstract
A process for making materials for road construction includes separating water from oil well drilling mud or other waste material sludge to form a partially dried sludge. The partially dried sludge is subjected to heat to further to dry the sludge. The dried sludge is combined with an open cell aggregate in plug mill to form a product. This product has a thermal conductivity of approximately 0.36 B.t.u./(hr.)(sq. ft.)(deg.F./ft.). The product is then deposited over frozen ground during the construction of a road.

A process of making materials for and constructing a road over frozen ground, said process comprising separating water from waste material sludge to form a partially dried sludge, subjecting the partially dried sludge to heat to further dry the sludge, combining the dried sludge with an open cell aggregate to form a product having a thermal conductivity between 0.30 to 0.50 B.t.u./(hr.)(sq.ft.)(deg.F./ft.), and depositing the product over frozen ground to form a road.
