Active Mitigation of Low-Temperature Cracking in Asphalt Pavements

Autor: Quentin Félix Adam, Asmus Skar, Gerald Englmair, Eyal Levenberg

Publikováno v: RILEM Bookseries ISBN: 9783030464547

Asphalt pavements in cold regions are often exposed to low-temperature cracking distress. The driving mechanism for this type of damage is usually an isolated event of fast surface cooling in combination with low-temperature levels. Another common ch
