A Review Of The Qualities And Utilization Of Waste Materials In Warm Mix Asphalt Concrete
The amount of unwanted waste produced in recent decades has quickly increased due to rapid population growth, technological advancements, and the widespread use of state-of-the-art products and services in the industry. Different researchers have carried out extensive studies on waste materials. Regretfully, most investigations focus only on the performance of HMA concrete that has been modified using one or two types of waste. Therefore, this study investigates an extensive review of the qualities and utilization of four types of wastes, viz., Coal Bottom Ash (CBA), Waste Cooking Oil (WCO), Waste Engine Oil (WEO), and Rice Husk Ash (RHA), as well as assessing their bibliometric analyses. The wastes that were being investigated showed a notable improvement in Warm Mix Asphalt (WMA) concrete. The WMA technology has successfully reduced the environmental issues of high production and compaction temperatures. The previous publications on CBA, WCO, WEO, and RHA identified 3,914 published documents between 2009 and 2023. Only 32 of these documents were published by Scopus. The academic disciplines of engineering, materials science, environmental sciences, and others have contributed 37%, 29%, 19%, and 15%, respectively, to Scopus publication. The United Kingdom made a significant contribution of 50% to Scopus publication compared to other countries. Furthermore, the findings also revealed that 89.4% (29 documents) were technical articles and only 10.6% (3 documents) were review articles. Further review of the rheological and microscopic properties of the four wastes is needed.
The First Application Of Ultrahigh Performance Concrete Link Slab In Malaysia
Conventional expansion joints in road bridges often suffer from issues like leakage, debonded seals, concrete damage, and short service life. To address these problems, a solution involving flexible link slabs using normal strength concrete (NSC) was proposed. While this method can enhance serviceability and reduce maintenance costs, it lacks durability and tensile strength. Recent interest has focused on cast-in-situ ultra-high performance concrete (UHPC) link slabs due to their exceptional mechanical properties, early strength, durability, ductility, and energy-absorption capabilities. However, there is limited information on their field implementation. To address this gap, a pilot UHPC link slab was designed and implemented to replace a damaged bituminous plug expansion joint in a Malaysian road bridge. The pilot link slab followed New York State Department of Transport (NYSDOT) guidelines and used a high early strength UHPC mix with minimal shrinkage through the combination of expansive agents and shrinkage-reducing admixture (SRA). Monitoring the project over two years has shown no performance concerns with the UHPC link slab. This paper provides a comprehensive overview of the construction process, along with experimental results on the mechanical properties and shrinkage characteristics of the new UHPC.
Utilization Of Zycotherm-SP2 On Warm Mix Asphalt Concrete – A Modern Technology
The increase of environmental concerns has been a promising force behind the existing study on zycotherm-SP2 (ZT-SP2) as part of the possibilities to decrease air pollution in the construction sector through the use of warm mix asphalt (WMA) modern technology. This paper, therefore, provides a modern technology for using ZT-SP2 on WMA concrete. The novel aspect of this work is the alteration of asphalt binder by the use of a ZT-SP2, a revolutionary warm mix additive product. With the help of the eco-friendly material ZycoTherm, asphalt may be produced at lower temperatures between 10 and 15 degrees Celsius, and at lower densities between 30 and 40 degrees Celsius. Published research has shown that adding CBA improves the structural performance of asphalt concrete pavements. Several studies have been made to enhance many types of WMA technologies (chemical, organic, and foaming additives) however, conflicting outcomes have been reported for several recognized features. All experiments were done in a laboratory setup. The summary of the results showed that the use of a ZT-SP2 dose of not more than 0.1% enhances the performance of WMA concrete. An additional in-situ study is needed to prove the performance of ZT-SP2 in real situations.
Utilizing Ultra-High Performance Concrete Overlay For Road Pavement Repair And Strengthening Applications
This study aims to develop a new thixotropic ultra-high-performance concrete (UHPC) overlay for the repair and strengthening of damaged hot mix asphalt (HMA) pavements. The overlay is purposely designed to accommodate the roadway slope of up to 10% due to presence of viscosifying agent materials. The original UHPC materials are comprised of granite aggregate, ultra-fine calcium carbonate, shrinkage-reducing admixture, viscosifying agent, and expansive agent. The study is conducted with three sets of samples provided and considers thixotropic and mitigated shrinkage properties through comparing control (non-thixotropic) overlay 1 (thixotropic), and overlay 2 (thixotropic) mixtures. Based on the obtained results, only overlay 1 corresponds to the minimum requirement for pavement rehabilitation, with 160-200 mm flowability and -545.3 µm/m free shrinkage. As a result, an average 50 mm thick overlay 1 is selected to repair a damaged HMA pavement (1800 m2), while the field implementation procedures and drawing details are also presented in this paper.
Effect of Waste Cooking Oil on Warm Mix Asphalt Block Pavement – A Comprehensive Review
Waste cooking oil (WCO) is an innovative alternative to modified binder materials for asphalt block pavement. Instead of discarding the WCO as unwanted material, modern scientific approach has supported the application of WCO as a defensible binder rejuvenator for asphalt block pavement, thus improving the significance of bio-oil waste (BoW) through reclamation. The effects of WCO on warm mix asphalt (WMA) block pavement and advanced bitumen replacement agents are reviewed. Similarly, the structural performance of WMA block pavement incorporated with WCO is summarised. High volume of WCO has been reported to upset the design life and mechanical behavior of the asphalt block pavements due to the waste oil constituents. Improper management of WCO in the pavement industry is a vital challenge to the environment and should be evaded. The integration of WCO in WMA block pavement is a credible solution to promote sustainable management of wastes. The most difficult task is in the reprocessing of WCO sufficient for the WMA pavement to withstand the pressure exerted on it. It is likewise essential to reprocess these BoW in an orderly atmosphere to preserve its consistency and structural performance. Reprocessing WCO for various applications of pavement contribute towards resource conservation, carbon emission reduction and pave the way towards responsible consumption. As long as the cost gap between the industrial and produced oils is optimized, the application can become not just feasible, but also economical. Based on a universal analysis of the structural behaviour discovered, there are noble projections regarding the imminent application of WCO solutions in pavement construction industry, especially for lightweight and mediumweight block pavements. However, to the best of our knowledge, the preceding reviews do not characterize recent WMA blocks integrated with WCO as a binder rejuvenator. As such, there is need for further studies on effects of unused cooking oil on either cold, warm, or hot mix asphalts block pavements.
