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.
