Infrastructure is Failing—But These Roadway Material Innovations Could Help

‘Tis the season of the pothole—and a myriad of other problems to do with road infrastructure. Winter brings out the worst in pavement: once water penetrates surface cracks, it expands as ice in freezing temperatures, weakening and displacing the surrounding asphalt. After thawing, the affected area remains a void for repeated water infiltration and freeze-thaw damage, eventually leading to larger cracks and potholes. According to the American Society of Civil Engineers’ (ASCE) “2017 Infrastructure Report Card,” U.S. roadways are suffering from these effects—so badly, in fact, the ASCE gave roadways a D-rating. “One out of every five miles of highway pavement is in poor condition and our roads have a significant and increasing backlog of rehabilitation needs,” the report reads. “After years of decline, traffic fatalities increased by 7 percent from 2014 to 2015, with 35,092 people dying on America’s roads.”
