Two of the most significant failures of asphalt roads are formation of ruts in the pavement surface due to highly concentrated loads at high temperatures, and cracking of the outer asphalt layer especially at low temperatures. In the last years, polymers are used as bitumen modifiers to delay the formation of ruts as well as for improving the resistance against cracking.
