Special Issue Information

Dear Colleagues,

Pavements are an important component of highways, airports, and ports. The evaluation of pavement performance is crucial for assessing its ability to support traffic over time and to determine maintenance and rehabilitation strategies. Moreover, materials performance evaluation seeks to advance the technology and tools used for the evaluation, testing, specification, mixture proportioning, and optimization of the materials used in the construction, preservation, maintenance, and rehabilitation of highways. There are a broad range of paving materials, including traditional materials—asphalt, Portland cement concrete, and aggregate—as well as recycled, reused, new, or innovative materials.

We invite researchers from across the world to contribute original research articles as well as review articles on the evaluation of pavement and materials performance. Suggested topics related to this Special Issue include the following:

  • Pavement performance evaluation:
  • Visual condition surveys (flexible and rigid pavements);
  • Non-destructive evaluation of the functional properties of pavements (roughness and skid resistance);
  • Non-destructive evaluation of the structural properties of pavements (e.g., Falling Weight Deflectometer (FWD), Dynamic Cone Penetrometer (DCP), Air-coupled Ground Penetrating Radar (GPR), Ground-coupled Penetrating Radar (GPR), seismic evaluation tools, and Total Pavement Acceptance Device (TPAD));
  • Destructive evaluation of the structural properties of pavements;
  • Geotechnical investigations of pavement structures.
  • Innovative approaches to pavement analysis and design;
  • Performance models of flexible and rigid pavements;
  • Constitutive modeling and experimental characterization of pavement materials (asphalt binder, aggregates, asphalt mixes, cementitious materials and Portland cement concrete, unstabilized and stabilized bases, and subgrade soils);
  • Numerical response analysis of pavements under static and dynamic wheel loading and climatic conditions;
  • Experimental characterization and modeling of permanent deformation, fatigue cracking, low-temperature cracking, and moisture damage in pavement layers;
  • Microstructure characterization and micromechanics of asphalt concrete, cementitious materials, and Portland cement concrete;
  • Modeling the behavior of pavement materials in mixing, laboratory and field compaction, and service.

The large amount of recycled asphalt pavement mixture (RAP) generated during renovations has a negative impact on the environment. In recent years, how to rationally recycle and reuse RAP has become a hot research direction in the field of highway construction. However, the recycled asphalt binder has some problems such as instability, easy aging and decreased adhesion. In this paper, carbon nanotubes and waste engine oil were used to modify recycled asphalt binder. Through a high-temperature rutting test, low-temperature bending test and Marshall stability test, the properties of an asphalt mixture with 40% RAP modified by carbon nanotubes and waste engine oil, an asphalt mixture with 40% RAP and an asphalt mixture without RAP were compared and analyzed. The tests showed that 1.5 wt% carbon nanotubes could improve the performance of the old asphalt binder most significantly. After adding 1.5 wt% carbon nanotubes, the high-temperature rutting resistance of the asphalt mixture was increased by 24.3%, and the bending stiffness modulus and the best crack resistance at low temperature increased significantly. In addition, after adding 1.5 wt% carbon nanotubes, the Marshall stability of the waste-engine-oil-modified RAP could be restored to the level of the new asphalt mixture. In summary, carbon nanotubes can improve the high-temperature stability, low-temperature crack resistance and Marshall stability of waste-engine-oil-modified RAP. Full article

Spent fluid catalytic cracking catalysts (S-FCC-Cs) constitutes a fraction of the hazardous solid waste generated in the petrochemical industry. The resource application of S-FCC-Cs remains a challenge. This study aims to explore utilizing S-FCC-Cs in asphalt mortar as a means to enhance resource utilization. Five different S-FCC catalysts were used as substitutes for mineral powder in the asphalt slurry at varying proportions. The high-temperature rheology of the resulting spent FCC catalyst-modified asphalt slurry was analyzed using temperature scanning tests and multiple stress creep recovery (MSCR) tests conducted at different temperatures and substitution doping levels. As the proportion of alternative doping increased, both the phase angle and irrecoverable creep flexibility decreased, while the absolute values of the rutting factor, deformation recovery rate, and irrecoverable creep flexibility difference increased. Moreover, as the temperature rose, the phase angle increased while the rutting factor decreased. The inclusion of an alternative admixture significantly improved the high-temperature performance of the asphalt mastic. This improvement was attributed to several factors, including the increase in the elastic component, enhanced deformation resistance, and improved deformation recovery. While the high-temperature performance of spent FCC catalyst-modified asphalt mastic gradually declined with increasing test temperature, all performance indices remained superior to those of limestone mineral powder asphalt mastic. In addition, the asphalt mortar modified by S-FCC-C JX with a surface area and hydrophilic coefficient of 105 m2/g and 1.026, respectively, exhibited the best rutting resistance and resilience performances among the five mortars, suggesting that the two factors co-affected the high-temperature rheological properties of S-FCC-C asphalt mortar. Considering stress sensitivity, it is more advantageous in improving the high-temperature deformation resistance of asphalt slurry at the JX dosage of 20%. These research findings offer valuable guidance for the application of S-FCC catalysts in asphalt pavement. Full article
