Jose P. Gomez, Ph.D., P.E., Associate Director

This study involved the construction and early performance of the first bridge in Virginia constructed with lightweight high-performance concrete (LWHPC) having a density of 120 lb/ft3 in the beams and deck. The design strength and permeability were 8,000 psi and 1500 coulombs, respectively, for the beams and 4,000 psi and 2500 coulombs, respectively for the deck.
