New Test Method for Determining Walkability of Steep-slope Underlayments
1. Scope
This test covers the determination of slip resistance of asphalt-based and polymer-based steep-slope underlaymentsKeywords
asphaltic; felt; polymeric; organic; inorganic; fiber-reinforced; polyethylene; polypropolene; syntheticRationale
A test method for walkability--most recently--comes from the development of the Synthetic Underlayment standard (quire recent initial publication). Negatives about slip resistance of these products were unresolved until Matt Dupuis and I volunteered to chair a TG to develop/reinvent a test method for slip resistance of steep-slope underlayments. This is important for manufacturers and contractors for rooftop safety of workers. Manufacturers will be able to list Walkability / Slip Resistance as a physical property of underlayments so users of products can compare Walkability from product to product.
