Understanding Roof Underlayment Decra
Manufacturing organic asphalt-saturated felt underlayment is a pretty straight-forward process. Recycled paper is processed into a roll. Hot asphalt is then added to the roll and asphalt-saturated underlayment is formed. In the past, the felt number designation was correlated to the weight of the felt (i.e., a 15# felt weighed 15 lbs/100 For many years, roofers used asphalt saturated felt under roofing shingles, and it was historically available in two standard weights: 15 pounds per hundred square feet and 30 pounds per hundred square feet. The 15 pound was for lighter weight projects, while the 30 offered more heavy duty protection.The Purpose of Roofing Felt Is Roofing Felt Necessary? IKO

Mechanical characterization of the elastoplastic response of asphalt
In the present work, we propose to perform the mechanical characterization of the asphalt felt paper through an infinitesimal-strain rate-independent elastoplastic model that assumes orthotropy for both the elastic and plastic responses.
