“…Several factors can result in fatigue cracking of asphalt pavements, including traffic loading and freeze and thaw cycle, which causes high stress on the asphalt pavement (Read et al 2003, Dulaimi et al 2020. A repeated loading pressure fatigue creates cracking in two phases: the crack initiation phase through micro cracks and the crack propagation phase through which the micro cracks increase under other applications of tensile strains (Read et al 2003).…”

“…The fatigue life can be defined as the number of required cycles to achieve a decrease of a 50% in the original stiffness of the mixture. According to (Dulaimi et al 2020), the strain level (150 microstrains) in a pavement structure depends on variables including the type of mixture, the road load, the layer thickness and subgrade. Tests were executed on prismatic samples measuring 400 × 50 × 50 mm at a frequency of 10 Hz and a temperature of 20°C under a sinusoidal waveform in a preset strain mode.…”

Conventional hot mix plants operate to support large paving projects, making production more economic with high volume output. When repairs and maintenance are needed, it can be challenging to maintain small quantities of hot bituminous mixtures at a sufficient temperature, especially in the case of winter maintenance. Consequently, the repair materials cannot be compacted to the desired level on some occasions. This research aimed to develop a polymer modified asphalt binder with reduced temperature sensitivity for hand-laid and low-volume applications. The results showed that the highest penetration index has been achieved by modifying bitumen with 20% rubber and 2% wax. The FTIR and XRD analysis indicated that the bitumen, rubber and wax that react chemically to build 3D networks have an interlocked structure in the bitumen matrix resulting in reduced temperature sensitivity of the polymer modified asphalt binder. Furthermore, indirect tensile stiffness, permanent deformation, creep test and fatigue life test, water sensitivity and freeze-thaw cycle demonstrated an improvement in the asphalt mixture properties in terms of mechanical and durability perspectives. Overall, based on this investigation, modifying asphalt binder with 20% rubber and 2% wax resulted in stronger and durable asphalt mixture in comparison to traditional hot mix asphalt.

“…Yet, substantial industrial waste, called calcium carbide residue (CCR), is also generated during the production of acetylene gas, often in large amounts because of the high demand for acetylene gas; it is estimated that China alone produces 28 million tons of CCR annually [ 2 ]. The CCR is mainly composed of calcium hydroxide, which has high alkalinity [ 3 , 4 , 5 ], so the accumulation of considerable high-alkaline CCR has a detrimental role in the environment and ecology [ 6 ], via its water alkalization as well as biological impacts [ 7 ]. In addition, CCR often contains heavy metals, whose migration during rains can lead to heavy metal pollution in both the soil and water.…”

Calcium carbide residue (CCR) is a solid waste resulting from acetylene gas production. In this study, CCR was used as an alkali activator to prepare fly ash (FA)-based geopolymers without any alkali supplementation. We studied the factors (FA/CCR ratio, curing temperature, and water/binder ratio) influencing the mechanical property of FA/CCR-based geopolymers. The compressive strength results showed that, by optimizing these three factors, the FA/CCR mixture has great potential for use as a cementitious material and geopolymer with a dense microstructure having a maximal compressive strength of 17.5 MPa. The geopolymers’ chemical structure, microstructure, and chemical composition were characterized and determined by a combination of techniques. All these results revealed that amorphous C-(A)-S-H (calcium (aluminate) silicate hydrate) gels mainly formed after geopolymerization resulting from the reaction of FA and CCR. In addition, some crystallines, such as ettringite and monosulfate, were also formed. Further, geopolymers prepared with a suitable FA/CCR ratio (1:1 or 1:2) possessed a compact microstructure because of their sufficient reactive SiO2 and Al2O3 and high-enough alkalinity, responsible for higher content of C-(A)-S-H formation and better mechanical property. Too high curing temperature or water content induced the formation of a loosely bound geopolymer matrix that strongly weakens its mechanical property.

“…The main role of the filler that it fills voids between aggregates in the mixture and modify the properties of the HMA binder, because the filler acts as an integral part of the mastic (combination of bitumen, filler, and entrapped air), The usage of the lime waste as a filler improves the stiffness and the resistance of the permanent deformation at different values of temperature [1]. The usage of the solid wastes is now taking a higher attention for the industrial countries, the continuous increasing of the by-product wastes requires a huge landfill space which could be noneconomical and harmful for the environment [2], the optimum bitumen content was found using Marshal Experiment. One of the advantages of the Marshall Mix Design method is that the performance of the mixes can be expected for local materials and environmental impact [3].…”

It is obvious that the type of fillers has a significant effect on the properties of hot-mix asphalt (HMA). It is very important to understand the effect of these types of fillers on the HMA and its performance. This paper represents laboratory research into the different effects of the bi-product fillers on the properties of HMA mixture. Four types of filler and three filler contents for each were used to obtain the characteristics of HMA and to characterize the effect of filler in HMA. The effects of filler on the of HMA mixture were also studied. The properties of HMA evaluated include Marshall Test and indirect tensile (ITS). The research results showed that fillers had a great influence on the properties of HMA. With the increase of filler content, some properties of HMA improved.
