Rationale

Currently, the only material standard for hot rubberized asphalt roofing and waterproofing is a former Canadian standard CGSB 37.50:M89 for Hot Applied, Rubberized Asphalt Roofing and Waterproofing. This standard has been withdrawn and is not current. The proposed new standard will set a consensus-based guideline for hot rubberized asphalt material properties. It can be used by architects and engineers to specify new roofing and waterproofing assemblies.
