“…The smaller value for steel slag indicates that steel slag has a better wear resistance and better mechanical properties than granite. This is congruent with the findings of a study conducted by Hainin et al [17]. Zumrawi & Khalill [18] stated that steel slag has a good mechanical properties and are therefore suitable for use as aggregate materials.…”

The volume of waste generated in Malaysia and throughout the globe continues to increase. Waste management and protection of the environment should be given a priority, and this requires for studied to be carried out on the problem of waste management. One of the approaches that can be adopted in this regard is to reuse waste materials as recycled products. Mechanical and geotechnical tests, namely the Los Angeles abrasion tests, the Atterberg limit test, and the sand equivalent value, were carried out to determine the suitability of using steel slag and CRT glass in the construction of road pavements. The value obtained from the laboratory test is within the JKR standard specification (JKR/SPJ/2008-S4). The objective of this study is to investigate the mechanical and geotechnical properties of steel slag and cathode ray tube (CRT) glass in order to determine the feasibility of using both materials as a natural aggregate replacement in the construction of road pavements. The result for the Los Angeles abrasion test showed that steel slag has better wear resistance and mechanical properties compared to those of the natural aggregates (granite) use in this study. The result for the Atterberg limit test showed that all three samples (granite, steel slag and CRT glass) are non-plastic. While the result for the sand equivalent value test showed that the granite sample has the highest value, followed by CRT glass and steel slag. Thus, it can be concluded that steel slag and CRT glass are suitable substitutes for natural aggregates (granites) since they have been proven to meet the requirements for the natural aggregates with similar properties. This provides an alternative use for recycled materials and the possibility of using these materials as an aggregate replacement in the construction of road pavements.

“…In many locations across the globe, subgrade soils are, in general, not suitable for use as a pavement foundation, and a suitable fill is difficult to find in many instances. So, depending on regions, anthropogenic materials like blast furnace slags and burnt and unburnt mining wastes (clay shales) are more often used for construction as reported by Haibin and Zhenling [1], Ebrahimi, et al [2], Rafalski and Wilczek [3], Akbarnejad, et al [4], and Hainin, et al [5]. e key to success is the long-term stability of such materials due to possible mineralogical changes reported by Adamczyk et al [6].…”

This paper summarizes the findings from laboratory and field performance testing of reclaimed hydrated class C fly ash (HFA) stabilized with a triangular aperture geogrid. This phase of testing was performed on HFA laboratory specimens and field test sections. The laboratory test results provided estimates for design input values, while the field testing assessed performance characteristics including the as-constructed modulus of the subgrade reaction, the in situ resilient modulus, and permanent deformation. For the laboratory portion, all results were derived from tests conducted on specimens immediately after sample preparation and after a 7-day cure. The compressive strength of reclaimed hydrated class C fly ash increases with curing. The strength of the HFA material can be further increased when mixed with a chemical stabilizer. For this project, chemical stabilization with lime was not viable because the lime supplier was too far from both HFA source and project site. Based on cyclic plate load tests, the in situ resilient modulus of the HFA and geogrid-stabilized HFA layers were determined on site. This paper reports the findings from the laboratory and field plate load test and highlights the potential use of geogrids in the stabilization of HFA.

“…e nonmetallic mineral, like diatomite [19] and steel slag filler [20], was also conducted to enhance the resistance of permanent deformation and moisture for asphalt mixtures. Another feasible approach referred to as asphalt mixtures prepared with an alternative aggregate of steel slag has been involved [21]. As a coproduct of the production of iron and steel, steel slag caused increasing pressure on land occupation and dump fees due to its enormous output and lower utilization rate [22].…”

Previous studies have indicated that steel slag can be used as a substitute for natural aggregates in asphalt mixture, while little attention has been paid to systematic investigation of the influences of various external environmental factors on deformation resistance of steel slag asphalt mixture. In order to understand the service behavior of steel slag asphalt mixture, its permanent deformation under different condition was investigated based on an indoor simulation test. The chemical composition, microscopic structure, surface texture, and volume stability of steel slag were firstly characterized. The uniaxial repeated loading test and standard wheel-tracking test were applied to evaluate the effect of temperature, stress levels, and water damage on the permanent deformation of AC-16 and AC-20 steel slag asphalt mixtures. The results indicate that a higher content of alkaline oxide and high-grade texture index existing in steel slag contribute to its strong absorptivity and adhesion of asphalt. The steel slag demonstrates fine volume stability due to its lower free-CaO (f-CaO) content, autoclave chalked ratio, and immersion expansion ratio. The permanent deformation of steel slag asphalt mixtures increases rapidly under higher stress and temperatures in contrast to lower increment at lower stress and temperatures. Asphalt mixtures at higher stress and higher temperatures and water condition exhibit larger rutting deformation and inferior rutting resistance. AC-16 steel slag asphalt mixture has superior resistance to permanent deformation than AC-20 asphalt mixture. Rutting factors show different degrees of impact in a decreasing order of temperature, water damage, and stress levels. The findings have significant implications for providing a theoretical basis for reusing steel slag in pavement construction and facilitating engineering application of steel slag asphalt mixture.
