1. A multiscale approach for predicting freeze-thaw damage in asphalt mixtures
Sammanfattning : Cold and wet climates are a known threat to asphalt pavements, causing both an embrittlement of the material, making it more prone to failure, and increasing the risk of damage due to the presence of moisture in the material and freeze-thaw cycles causing expansion and contraction of the air voids as the moisture inside them freezes and thaws. This damage evolution can lead to an overall decrease of material properties and ultimately showcase itself as raveling, pot holes,and cracks. LÄS MER
2. Towards frost damage prediction in asphaltic pavements
Sammanfattning : Roads are subjected to mechanical loads from the traffic as well as deteriorating mechanisms originating from the surrounding environment and climate. The damage arising is particularly severe during the winter season, when for example raveling, pot holes and cracks can emerge on the surfaces of asphaltic roads. LÄS MER
