A road without fibers is a road soon to be in need of repair
New research is reaffirming the benefits of steel or synthetic engineered fibers in asphalt pavements and concrete, where they enhance performance, replace fine matter, and in the case of concrete, control shrinkage cracking and keep deicing salts away from reinforcing steel. For decades, fibers of all origins have been hawked as cure-alls for pavement problems. […]
