An ASTM International committee, D08 on Roofing and Waterproofing, is developing a standard for two asphalt products that will help reduce air emissions, save energy, and benefit workers by lowering their exposure to asphalt fumes.

The proposed standard, ASTM WK45660, covers asphalt that has significantly lower application temperatures in comparison to many other types of asphalt. The lower temperature makes it possible to lower the maximum kettle temperature, which further increases the benefits of the asphalt types.

According to Dave Trumbore, ASTM member and Owens Corning consultant, in addition to lower application temperatures, the covered asphalts are high performance and user-friendly. They are used to make low-slope roofs because the asphalts have good aging and high ductility purposes.

Interested parties are invited to contribute to the ongoing work on WK45660, which is being developed by subcommittee D08.03 on Surfacing and Bituminous Materials for Membrane Waterproofing and Built-up Roofing.
