Special Issue Information

Dear Colleagues,

With the world population increasing, the amount of waste generation is growing rapidly. This amount of waste causes a huge rise in the cost of waste disposal and is filling future sites for landfills. Many studies are being conducted to research the advantages of reusing waste material in an economically and environmentally sustainable way. Many investigations on the effects of reusing hazardous materials on construction material properties and their environmental impacts have already been conducted. Due to the lack of raw materials and natural resources, using waste solid material in civil engineering projects, especially road construction, has become an issue worthy of consideration. Currently, the applications of waste by-product in geotechnical and pavement engineering are of great interest in research and development. Historically, because of the huge amount of material needed for construction, pavements have been suitable structures to recycle a wide range of waste materials. Finding reasonable and cost-effective solutions for waste material disposal, such as recycling, is one of the most important responsibilities of scientists, engineers, researchers, and governments. These solutions should not only consider the environmental advantages, but also reuse the solid waste materials in projects such as road construction. Therefore, effective recycling of waste is one of the solutions sought by many researchers. Well-managed recycling of waste has several advantages, including:

  • Contributing to the reduction or prevention of exhaustion of natural resources;
  • Contributing to a reduction of environmental contamination due to the uncontrolled disposal of waste materials produced by industrial and domestic consumption;
  • Significantly saving money and energy.

This Special Issue seeks original research presented as review articles which display the past and current development of geotechnical and pavement construction. In addition, this Special Issue is interested in investigating the feasibility and challenges of using waste materials in geotechnical and pavement design. This is an invitation to all geotechnical and pavement engineers, materials  researchers, and road design contractors and users to contribute experience and the results of research and consultancy projects.

Evaluation of Low- and Intermediate-Temperature Performance of Bio Oil-Modified Asphalt Binders

Abstract
Fatigue cracking and low-temperature cracking are two major distresses that occur in asphalt pavements. Fatigue cracking is a load-associated distress caused by the tensile stresses at the bottom/top of the asphalt concrete (AC) layer due to repeated traffic loading. On the other hand, [...] Read more.
Fatigue cracking and low-temperature cracking are two major distresses that occur in asphalt pavements. Fatigue cracking is a load-associated distress caused by the tensile stresses at the bottom/top of the asphalt concrete (AC) layer due to repeated traffic loading. On the other hand, low-temperature cracking occurs when tensile stresses built up with in the AC layer at low temperatures exceed the tensile strength of that layer. In this study, the performance of date seeds oil bio-modified asphalt binders (DSO-BMB) is evaluated against fatigue and low-temperature cracking. The DSO-BMBs are prepared using volume ratios of 1.5, 2.5, 3.5, 4.5, and 5.5% date seeds oil-to-asphalt binder. The base asphalt binder used in the study is a 60/70-penetration grade with a Superpave performance grade (PG) of PG 64–16. The dynamic shear rheometer (DSR) standard test was used to assess the fatigue performance of the bio-modified binders (BMBs), while the bending beam rheometer (BBR) test was used to test the BMBs for low-temperature performance. In addition, the DSR linear amplitude sweep (LAS) test was used to evaluate the fatigue tolerance behavior of the DSO-BMBs. The analysis and results of the study showed that the bio-oil enhanced the low-temperature performance. The low PG grade improved from −16 °C for the control asphalt binder to −28 °C for the BMB. Additionally, the fatigue resistance of the BMBs was improved as illustrated by the damage–characteristic curves of the modified asphalt binders from the visco-elastic continuum damage (VECD) analysis and the increase in the number of cycles to fatigue failure (Nf).

The use of geopolymer in pavement constructions is strongly encouraged. Many studies have demonstrated the vast potential of using industrial-by-products-based geopolymers. This paper discusses the modification of asphalt binders with geopolymers, namely geopolymer-modified asphalt (GMA) and geopolymer-modified asphalt mixture (GMAM). In addition, curing geopolymer materials, engineering properties, production techniques, and prospective utilisation in the pavement construction, such as durability and sustainability, are also discussed. The literature review showed that many industrial by-products, including red mud, blast furnace slag, fly ash, and mine waste, are used to produce geopolymers because of the metal components such as silicon and aluminium in these materials. The geopolymers from these materials influence the rheological and physical properties of asphalt binders. Geopolymers can enhance asphalt mixture performance, such as stability, fatigue, rutting, and low-temperature cracking. The use of geopolymers in asphalt pavement has beneficial impacts on sustainability and economic and environmental benefits. Full article
