The heat conductivity of a cementitious roadway is improved by adding into the cementitious concentration a powder mixture of a tin alloy or a tin and other powder. Preferably, the alloy is a tin-niobium alloy. Alternatively, a tin powder and a niobium powder are admixed into the composition. Where the powders are used each of the components are present in a 50:50 weight ratio. The powder admixture can also be incorporated into an aqueous latex topcoat for application to a road surface. |
