Special Issue Information

Dear Colleagues,

Pavement construction is an essential part of modern infrastructure, providing safe and reliable transportation networks for people and goods. However, traditional pavement construction materials such as asphalt and concrete require significant amounts of natural resources and energy to produce, leading to a significant environmental impact. In recent years, researchers and engineers have been exploring the use of waste materials in pavement construction as a sustainable alternative to conventional materials.

The use of waste materials in pavement construction has gained increasing attention due to its potential to reduce the environmental impact of traditional pavement construction methods. For instance, construction and demolition (C&D) wastes can be used as substitutes for traditional materials in pavement construction. These waste materials offer several benefits, including reduced resource consumption, decreased landfill waste, and improved pavement performance.

The Special Issue on "The Application of Waste Materials in Pavement Construction" aims to provide a platform for researchers and practitioners to present their latest findings, developments, and applications related to the use of waste materials in the construction of pavement systems.

The purpose of this Special Issue is to promote the sustainable use of waste materials in pavement construction, which can help reduce the environmental impact of waste disposal and conserve natural resources. By bringing together the latest research and practical applications in this field, this Special Issue will provide valuable insights and guidance for researchers, engineers, and policymakers working in the area of pavement construction and waste management.

The scope of this Special Issue encompasses a wide range of waste materials that can be used in pavement construction, including recycled materials such as reclaimed asphalt pavement (RAP), recycled concrete aggregate (RCA), and recycled glass, as well as industrial by-products such as fly ash, slag, and bottom ash. The Special Issue will cover various aspects of pavement design, construction, and maintenance, including material characterization, mix design, mechanical properties, durability, and environmental impact assessment.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Material characterization: the physical and chemical properties of waste materials and their suitability for use in pavement construction.
  • Mix design: developing optimized mix designs for pavement materials using waste materials.
  • Mechanical properties: evaluating the mechanical properties of pavement materials containing waste materials, such as stiffness, strength, and fatigue resistance.
  • Durability study: evaluating the durability of pavement materials containing waste materials under various environmental conditions, such as freeze‒thaw cycles and exposure to chemicals.
  • Environmental impact assessment: investigate the potential environmental benefits of using waste materials in pavement construction.
  • Field performance evaluation: evaluating the performance of pavement materials containing waste materials in the field. 

We look forward to receiving your contributions.

There are ongoing research challenges for the addition of the blend of PET and crumb rubber in polymer-modified concretes, which aims to leverage the benefits of both materials. In this study, various percentage combinations of waste aggregates, such as PET and crumb rubber, were used to replace coarse and fine aggregates in natural rubber latex (NRL)-modified concrete. Engineering properties such as compressive and flexural strengths, modulus of elasticity, and toughness obtained from compressive- and flexural stress-strain curves were investigated. Scanning electron microscopy (SEM) analysis was performed to examine the microstructural properties and study the strength development of the studied concretes. The results revealed that the compressive and flexural strengths of NRL-modified concretes with PET and crumb rubber aggregate replacements decreased with increasing replacement ratios. SEM analysis indicated that PET and crumb rubber (hydrophobic and non-polar materials) can affect the microstructure of the studied concrete by creating a weak interface between the aggregate and cement pastes, leading to reduced strength development. With the addition of the NRL additive, the film formation was found to act as a bridge and improve the bond strength of aggregates and hydration products in NRL-modified concrete. Furthermore, the integration of PET and crumb rubber aggregate can enhance the ability of the concrete to absorb energy and improve ductility. It was found that 10% of PET and crumb rubber aggregate replacement can be used for NRL-modified concrete as a rigid pavement, as its mechanical strengths satisfy the requirements set by the Department of Highways (DOH) in Thailand. This research helps repurpose waste materials and reduce the environmental footprint of concrete production. Full article
