Abstract
This paper offers a review of previous research by the authors by means of the analysis of mechanical and environmental variables governing the mechanical behavior of hot bituminous mixtures, with special emphasis on damage, degradation and fracture. With regard to the mechanical factors affecting the structural performance of the mixtures, one can mention cyclic loading (mechanical fatigue) and heavy vehicles. In the matter of environmental factors influencing such a mechanical (damage & fracture) performance, the list is as follows: (i) de-icing salts, (ii) weather conditions, including temperature cycles (thermal fatigue), rainfall and presence of ice. Results are presented in systematic manner to draw conclusions and recommendations applicable to real traffic of vehicles in roads.
