Revision of D6164/D6164M-16 Standard Specification for Styrene Butadiene Styrene (SBS) Modified Bituminous Sheet Materials Using Polyester Reinforcements

Keywords

None Provided

Rationale

Load strain properties of D6164 sheets should be clarified especially when the sheet uses a polyester mat reinforced by glass yarns to improve processing in the manufacture of the sheet and to reduce distortions that may be introduced during production, as currently indicated in Note 1. When such a reinforcement is used, it is typical to observe two peaks in the load elongation curve. The glass peak that may be observed when testing these sheets must be properly accounted for in the analysis of the load elongation curve.
