“…In this context, several papers about the fatigue resistance of asphalt mixtures have been developed using the haversine waves in laboratory tests (Mamlouk et al 2012;Hernández et al 2013;Cooper Jr. et al 2013;Huang et al 2015). On the other hand, a wide range of studies have been using the sinusoidal waves (Eberhardsteiner and Blab 2017; Goli et al 2017;Varma et al 2016;Rasouli et al 2018;Melo and Trichês 2017;Almeida et al 2018;Melo et al 2018), revealing a disagreement among the researchers about the ideal waveform to be employed in the test. Therefore, caution is advised while comparing fatigue models obtained through standard procedures that were conducted under different loading.…”

An experimental study was conducted to determine the effect of deflection waveform on four-point flexural fatigue test results for hot mix asphalt. This paper reports how the waveform affects the fatigue resistance of an asphalt mixture and, consequently, the fatigue models of the material. The mix was tested at different strain levels under both haversine and sinusoidal deflection-controlled modes. The findings indicate that haversine displacement control testing results in a sinusoidal strain response of half the intended amplitude. This outcome was attributed to the viscoelastic nature of asphalt mixes. In the deflection controlled haversine test, permanent deformations lead to a new equilibrium neutral position of the beam and the force output follows a sinusoidal waveform. This produces erroneous fatigue results since the test assumptions do not match the actual test conditions. It is recommended to use a sinusoidal waveform to obtain consistent results.

“…Steel slag has many well-known applications in road construction such as asphalt mix aggregate [2,7,9,18,19], antiskid layer [20][21][22], granular base and subbase material [2,23,24]. Researchers have investigated application of steel slag in hot mix asphalt [25][26][27][28][29][30][31], warm mix asphalt [32][33][34][35][36][37], chip seal [38] and stone mastic asphalt [39][40][41]. Review of development in various aspects of utilizing steel slag in dense graded hot mix asphalt is presented herein.…”

“…To provide alternative to traditional construction materials, it is imperative to understand performance of asphalt mixes that are modified with new and recycled materials [42]. Laboratory and field experiments performed by researchers show that, inclusion of steel slag in asphalt mix may enhance the mix durability, skid resistance, stability, rutting resistance, affinity with bitumen [25,26,32,33,43,44]. The physical and chemical properties and proportion of steel slag can influence performance of hot mix asphalt.…”

Road construction involves large quantity of construction materials, primarily obtained from natural sources. Utilization of waste materials in construction activities can reduce burden on these natural sources. To achieve sustainable development, use of steel slag as a substitute to natural-aggregates has gained significant attention. Steel slag as aggregate has many well-known applications in road construction such as, hot mix asphalt, cement concrete mix, antiskid-layer, granular-base and subbase layers. This paper review development in various aspects of utilizing steel slag aggregate in dense graded hot mix asphalt. Properties of steel slag can significantly influence performance of roads. Chemical composition and physical and mechanical properties of steel slag have been reviewed in consideration of its suitability in asphalt mix. Findings from asphalt mix design studies indicate that, steel slag asphalt mix can be designed to satisfy both volumetric and mechanical properties. However, caution need to be exercised to ensure that addition of steel slag does not lead to undesirable change in performance of mix. Review of laboratory and field performance evaluation studies related to skid, m oisture, fatigue and rutting failures are presented in the paper.

“…Many researchers have devoted efforts toward the comprehensive utilization of steel slag and have made many breakthroughs. Currently, steel slag is used as a resource in the production of cement [4][5][6][7], road, bridge, and water conservancy project construction [8][9][10][11], and production of agricultural chemical fertilizers [12,13]. It also acts as a replacement to limestone in steelmaking [14] and is used to extract valuable metals [15].…”

Preparation of Steel Slag Ceramics with Different MgO/Al2O3 Ratios

et al. 2019

Steel slag, clay, quartz, feldspar, and talc were mixed to prepare steel slag ceramics. Crystalline phase transitions, microstructures, and the main physical-mechanical properties (water absorption, linear shrinkage, and flexural strength) of steel slag ceramics for various MgO/Al2O3 ratios were investigated by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and mechanical testing. The results indicated the significant effect of the MgO/Al2O3 ratio on these properties. A decrease in the MgO/Al2O3 ratio resulted in a major crystalline phase transformation from quartz and pyroxene phases to quartz and anorthite phases. High MgO content facilitated production of pyroxene phases. High Al2O3 content favored production of anorthite phases. The water absorption of all the samples (below 0.5%) met the Chinese national standard requirements. Samples with an MgO/Al2O3 ratio of 0.6 exhibited excellent flexural strength, reaching 62.20 MPa. FactSage software was used to predict batch viscosity, which increased with decreasing MgO/Al2O3 ratios.
