Portland concrete has been the guy forever, but a new alpha is sniffing around. ConFlexPave, developed by scientists at Nanyang Technological University in Singapore, is a concrete that's mixed with polymer microfibers to make it bendable and less prone to cracks. The claim is it will reduce construction time and increase worker safety at the jobsite. So far testing has been done only on tablet-sized slabs; road-sized experiments will be conducted over the next three years.
