Abstract:
In 2006, a bridge deck was constructed in China using a mixture of portland cement concrete and rubber crumbs. Although about 5% of the deck surface developed shallow shrinkage cracks shortly after placement, the rest of the deck remains crack-free. It is postulated that the crumbs create elastic joints that reduce stress concentrations near the tips of microcracks.
