Special Issue Information

Dear Colleagues,

Asphalt mixtures are composites consisting of aggregate and asphalt binders, and are the most commonly used paving materials globally. In recent years, new materials and construction techniques have been developed, such as warm-mix asphalt, cold in-place recycling, and various modifications and surface treatment methods.
This Special Issue, “Asphalt Mixtures with Reclaimed Asphalt Pavement”, will address advances in materials design, processing, characterization, testing, their mechanical properties, road construction, and maintenance methods of asphalt mixtures and pavements, including implementable techniques that are useful to practicing engineers and others.

We are pleased to invite you to contribute to this Special Issue, as we are seeking to gather a series of high-quality articles related to pavement materials. The topics of interest include, but are not limited to:

•    asphalt pavement design and analysis;
•    pavement recycling techniques;
•    fatigue, aging and self-healing of asphalt materials;
•    the use of waste materials in asphalt mixtures;
•    pavement monitoring and testing;
•    pavement evaluation and management;
•    sustainability/durability assessment of asphalt pavements;
•    asphalt binder modification.

This study is aimed at examining the mesoscopic mechanical response and crack development characteristics of asphalt mixtures using the three-dimensional discrete element approach via particle flow code (PFC). The material is considered an assembly of three phases of aggregate, mortar, and voids, for which three types of contact are identified and described using a modified Burgers model allowing for bond failure and crack formation at contact. The laboratory splitting test is conducted to determine the contact parameters and to provide the basis for selecting three different load levels used in the indirect tensile fatigue test and simulation. The reliability of the simulation is verified by comparing the fatigue lives and dissipated energies against those from the test. Under cyclic loading, the internal tensile and compressive force chains vary dynamically as a response to the cyclic loading; both are initially concentrated beneath the top loading strip and then extend downward along the loading line. The compressive chains are oriented roughly vertically and develop an elliptic shape as damage grows, while the tensile chains are mostly horizontal and become denser. An analysis based on the histories of the numbers of different contact types indicates that damage mainly originates from bond failures among the aggregate particles and at the aggregate–mortar interfaces. In terms of location, cracking is initiated below the loading point (consistent with observations from the force chains) and propagates downward and laterally, leading to the macrocrack along the vertical diameter. The findings provide a mesoscopic understanding of the fatigue damage initiation and propagation in asphalt mixture. Full article

Porous asphalt pavements are widely used in rainy and wet areas for their skid resistance, noise reduction, runoff minimization and environmental sustainability. Long-term moisture vapor erosion and the destabilization of large pore structures can easily result in pavement problems such as fragmentation, spalling, cracking, and excessive permanent deformation. To this end, four different preventive maintenance materials, including the rejuvenation (RJ), cohesion reinforcement (CEM), polymerization reaction, and emulsified asphalt (EA) types, were selected in this paper to improve the high-viscosity porous asphalt pavement. The effects of the different preventive maintenance materials on the temperature sensitivity, rheological properties and fatigue performance of high-viscosity modified asphalt were evaluated through temperature sweep, frequency sweep, multi-stress creep recovery (MSCR), linear amplitude sweep (LAS), and bending beam rheometer (BBR) tests. The results showed that the four preventive maintenance materials exhibit different enhancement mechanisms and effects. RJ improves the fatigue properties, deformation resistance and low-temperature cracking resistance of aged asphalt by adding elastomeric components; CEM materials are more conducive to increasing the low-temperature crack resistance of aged asphalt; while GL1 and EA improve the viscoelastic behavior of aged asphalt, but the effect of the dosing ratio needs to be considered.
