In December 2003, ASTM International's Committee D08 on Roofing
and Waterproofing held a technical symposium about roofing research
and standards development. The symposium was the fifth in a series
dating to the mid-1980s and provided some insight into current
research being conducted in the U.S. roofing industry.
The symposium consisted of presentations of 10 research projects
conducted by 31 researchers. The sidebar lists the presentation
titles. An overview of several presentations follows.
In "Measuring uplift resistance of asphalt shingles," adhesion
(uplift resistance) of asphalt shingles' self-seal strips is tested
by three test methods. The research's data show a "double-peel"
method of testing provides results between those derived using ASTM
D6381, "Standard Test Method for Measurement of Asphalt Shingle
Mechanical Uplift Resistance," and a "T-pull" method. The T-pull
method represents the case of more rigid shingles that generally
