ASTM D8139 requires more stringent tests than existing standards for joint fillers such as D1751 Standard Specification for Preformed Expansion Joint Filler for Concrete Paving and Structural Construction (Nonextruding and Resilient Bituminous Types), he adds.
By exceeding the standards set in ASTM D8139, Nomaflex easily meets the most critical requirements of D1751 and can be used as an 'equal to or better' alternative in any concrete expansion joint filler application where Nonextruding and Resilient Bituminous Types are used," explains Weimer.
