Use of an ester additive and paving grade asphalt in built up roofing asphalt composition manufacture
Thermally stable built-up roofing asphalt (“BURA”) composition comprising a paving grade asphalt is disclosed. The paving grade asphalt has been over-blown to a first softening point and an additive is included in an amount to achieve a second softening point. The additive comprises at least at least one ester. The BURA composition is thermally stable at processing temperatures of at least 450° F.
