Special Issue Information

Dear Colleagues,

Road infrastructures represent a fundamental asset for the economy of both developed and developing countries. Most paved roads consist of flexible pavements, and these are commonly designed with asphalt mixtures, which are a composite of asphalt binder, aggregate, and air voids. Such a composite material is required to fulfill different functionalities, such as providing a smooth and safe pavement surface while being capable of withstanding different load-induced phenomena due to traffic and climate actions. At low temperature, asphalt mixtures may experience significant distresses associated with the increase in thermal stress by itself, with the combination of thermal stress and traffic-induced stresses, with the fact that asphalt may become brittle at low temperature, or because of the thermal cycles linked with daily change in temperature. All this can eventually lead to cracking and failure. At the material level, this implies that not only the mixture itself, but also its constituents and its sub-phases (e.g.,mastic, mortar, and fine aggregate matrix) must provide adequate performance. Therefore, the development and use of precise laboratory characterization methods, chemo-mechanical analysis, modeling, simulations, and field evaluation and monitoring are required to determine the actual performance of asphalt materials.

In this Special Issue, the current characterization methods and modeling solutions addressing the behavior and performance of asphalt materials at low temperature are presented and discussed.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

The contact state between layers of asphalt pavement not only has a significant effect on the mechanical response of road structure but is also the bottleneck of research on the mechanical behavior of pavement structure at present. In this paper, the effects and laws of different water–salt entry modes, salt solution concentrations, and temperatures coupling on the contact state between base and surface layers are studied by a 45° inclined shear test. The simulation and verification of each working condition are carried out by ABAQUS (Dassault, Paris, France) the friction coefficient between layers is reversed, and the actual contact state between layers is characterized in order to realize comprehensive evaluation and reasonable expression. The results show that different modes have different effects on contact characteristics. At the same temperature and concentration of the salt solution, bonding of water and salt erosion is the best, followed by direct erosion, with the worst being from bottom to top, and the interlayer bonding condition is weakened with increase in temperature. The relative accuracy of the software simulation and test analysis was as high as 92% and the friction coefficient of the water-free salt erosion test piece was found to be about 0.85 at 25 °C, while after the bottom-up erosion of the 14% salt solution the friction coefficient was found to be about 0.43, which indicates that the corrosion of the water–salt will have a great effect on the bonding condition between the structural layers of the road.
