Claim:
Asphalt product which can be hot-poured and which hardens by means of simple cooling, of the type comprising mineral fillers such as fines, sand and optionally gravel; and a thermofusible binder, this binder being based on natural bitumen or bitumen from the oil industry, of the type comprising, in addition to this base product, a first additive which is constituted by a hydrocarbon wax which is substantially insoluble in the base bitumen of the binder at ambient temperatures and whose melting point, measured in accordance with the standards ASTM D3945 and D3418, is between 110° C. and 140° C., and which reduces the production temperature of the asphalt product relative to that of the base product, characterised in that it further comprises a second additive which is constituted by a fatty acid ester wax selected from montanic acid esters or lignoceric acid esters, this wax having a melting point, measured in accordance with the above standards, of less than 85° C., wherein the binder contains from 4 to 15% by mass of the total formed by the first and second additives relative to the total mass of the binder, and wherein the binder contains from 1 to 10% by mass of the second additive relative to the total mass of the binder.
