Special Issue Information

Dear Colleagues,

Currently, many new materials and techniques are being introduced to road construction in attempts to shift the industry to a more energy-efficient and sustainable trajectory. Incentives toward these goals are provided by global and government strategies, but these shifts may be also attractive to investors and contractors on their own, due to the possible reductions of construction costs. However, one has to bear in mind that road infrastructure projects are expensive and take long to finish, and that their role is key in the growth of the world’s economies. Therefore, it is crucial that the reliability and service life of these new types of pavements are assured. In the advent of new materials and methods in road construction, it is necessary to evaluate their impacts on the long-term performance of pavements.

The main emphasis of this Special Issue is on the relationships between the properties of asphalt mixture constituents (asphalt binders, aggregates, additives) and the performance of asphalt mixtures and pavements produced using modern methods. Therefore, we encourage results linking laboratory and large-scale performance of materials. Papers of narrower scope are also welcome and will be considered for publication. We are pleased to invite authors to publish research and review papers on the relevant topics as part of the Materials Special Issue titled ‘Modern Asphalt Pavements: From Constituent Material Characteristics to Pavement Performance and Applications’.

The technologies covered by this Special Issue are:

  • Hot-mix asphalt;
  • Warm-mix asphalt;
  • Half-warm-mix asphalt;
  • Cold-mix asphalt;
  • Asphalt recycling;
  • Polymer recycling;
  • Aggregate recycling;
  • Novel pavement rehabilitation techniques.

Kind regards

The paper presents the results of exploratory research on the use of reclaimed cement concrete in cold-recycled mixes with foamed bitumen. Because reclaimed cement concrete, unlike natural aggregates, is expected to have a residue of the non-hydrated cement covering the aggregate grains, which may result in a secondary cementation process after its application in a road base, this avenue was explored by tracking the time evolution of the compressive strength of the final material. The tests were performed using two mixtures, i.e., a reference mixture and a mixture containing 25% reclaimed cement concrete. The mixtures containing reclaimed cement concrete were characterized by increased uniaxial compressive strengths after each curing period (3, 4, 7, 14 and 28 days)—by 11.5 kPa on average and e.g., 498 kPa vs. 506 kPa after 28 days. The obtained differences between the mixtures were not found to be statistically significant. The small effects of the incorporation of reclaimed cement concrete were attributed to the time passed typically between the demolition and new pavement construction and to the presence of a second binding material—bitumen.

In cold regions, many types of structural damages are caused by the frost heaving of asphalt pavements. Hence, it is important to quantitatively determine the frost-heaving effect of asphalt pavement using a mechanical method to control frost-heaving damage. In this study, first, the internal voids of the asphalt mixture were regarded as a single void, and the water phase transition generating the freezing water in the voids was simulated using a simplified hollow sphere model to create a uniform internal pressure. Second, the prediction equation of the equivalent linear expansion coefficient was proposed by taking the phase transition of water in the saturated asphalt mixture voids into account. A step function was used during the phase transition of water to determine the sudden change in the equivalent linear expansion coefficient, heat capacity, density, and thermal conductivity. Finally, the typical cooling conditions were simulated with the water phase transition and the nonwater phase transition. The experimental results showed that the proposed model could accurately simulate the effect of frost heaving. Higher stress and strain were generated on the surface and in the interior of the pavement, and the positions of maximum stress and strain occurred on the pavement surface under the frost-heaving conditions. The compressive strength of the asphalt mixture in a uniaxial compression test is about 4.5–6 MPa with a single freeze–thaw cycle. Furthermore, when frost heaving occurs on the asphalt pavement between 5.8 and 6.5 MPa, the numerical simulation method can be used to calculate the internal stress of the structure, which found that the compressive stress under the frost-heaving condition was the same magnitude as the compressive strength under the freeze–thaw testing condition.
