No - Asphalt pavement is an asphalt mix (means mixture of fine aggregate, coarse aggregates and binding bituminous material (as the cementing material) with specific proportions and sometimes additions.

Asphalt used in roofing is merely the bituminous material used - however, the bituminous materials used in insulation has different charachtristics than that used in asphat mix

No. While both paving and roofing asphalts are derived from the petroleum refining process, they are used in very different ways.

Asphalt used in roofing is typically a harder grade of asphalt that is heated to much higher temperatures than those used in paving operations.
