“…Previous geotechnical study carried out by Meddah [13] indicated that foundations soils of this region are composed mainly of a large layer of dune sand with several meters of depth. The physical properties of this sand, usually used in Algeria for construction and transportation field, are shown in Table 1, while its particle size distribution and granulometric characteristics are shown in Fig.…”

“…Balunaini et al [2] reported that rubber waste can be used in several civil engineering applications such as embankment fill material, drainage material, vibration dampening material underneath railways, thermal insulation layer and asphalt rubber paving layer. In addition, rubber wastes were used as fine and coarse aggregates in concrete material as reported in several investigations [7,9,13,18,21].…”

In this study, an alternative and environmentally friendly method for the reinforcement of dune sand is proposed. This technique consists of using randomly distributed rubber fibers to improve the engineering properties of sand. Rubber fibers are added to the sand with different percentages: 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75 and 2% of dry weight of sand. The experimental program carried out consists of investigating the effect of rubber fibers on the shear strength properties of sand. Reinforced and unreinforced samples are tested in the dense as well as loose state. The results obtained showed that the inclusion of rubber fibers in dune sand will improve the engineering properties of various civil engineering applications such as shallow foundations and slope. Therefore, incorporation of rubber fibers can enhance the shear strength characteristics, peak and residual strengths, and introduce more ductility to the mechanical behavior of sand. In addition to the technical effect, this paper emphasizes another environmentally attractive option, which is the use of rubber fibers as reinforcements for granular soils as this helps to remove some parts of these wastes and protect the environment.

“…Thus, this concrete can be used at a rubber content of 2.5% of total aggregates and treated in benzene in paving highways. The compressive strength improved in the case of treating CR particles with benzene than treating them in water as shown in Figure 5, where the treatment of CR particles with benzene makes their surface rough, because benzene removes zinc salts in rubber [1,15] which increases the adhesion of cement mortar and surface of CR particles, and thus improves the compressive strength of concrete. While in the case of treatment CR with water there is weak bonding between CR particles and cement past [16,17].…”

Recently, the increasing number of used tires in landfills has become a major issue. The tire waste is burned, which results hazardous gases that further affect the earth's natural ecosystem. The main objective of this research is to investigate the partial replacement feasibility of fine and coarse aggregates with treated crumb rubber on fresh and hardened characteristics of concrete. This is reducing the consumption of natural resources utilized in concrete. Total aggregates were replaced by crumb rubber (CR) in the concrete mixture at ratios of 2.5%, 5%, 7.5%, and 10% by volume. CR particles were treated by two methods, the first method is soaking in water and the second method is treating by placing CR particles in benzene. The findings indicated that the compressive strength decreased by 20%, 31.67%, 43.33%, and 53.33% than that of the reference mix at 28 days of curing in the case of water treatment, while it decreased by 10%, 16.67%, 33.33%, and 40% in the case of benzene treatment at the ratios of CR 2.5%, 5%, 7.5%, and 10%, respectively. The increase in CR content reduced the modulus of rupture of mixes by 11.6%, 20.9%, 34.9%, and 44.18% in the case of treating CR particles with benzene at ratios of CR 2.5%, 5%, 7.5%, and 10%, respectively. The modulus of elasticity decreased with a higher ratio of CR particles making concrete containing CR suitable for use in pavement, playgrounds, and machine bases. The mixture with the replacement of 2.5% CR of total aggregates and treated with benzene was considered the best mixture containing rubber as it had a little reduction in strength of compressive, modulus of rupture, and indirect tensile with comparison to the reference mix. When the ratio of CR particles was increased, the density of the mixtures decreased.

“…Although the above methods solve the problem of melting ice and snow, it also induces some new problems. Rubber particles in elastic pavement increase the difficulty of pavement compaction, and elastic pavement may also increase vehicle fuel consumption [19]. e low-freezing point additives in pavement slowly dissolve, and this solution is under the condition of osmotic pressure, which means that it will also be slowly released in the rainy season.…”

Elastic pavements, low-freezing point pavements, and energy exchange pavements meet the function of road ice and snow melting but may damage the pavement performance. To solve the above problems, this study intends to develop a noncontact snow-melting pavement by using induction heating technology. The steel wool asphalt mixture was prepared, and the effects of steel wool on road performances including the high-temperature performance, low-temperature performance, water stability, and fatigue performance were studied. The influence of the asphalt mixture’s factors, environmental factors, and human factors on the ice-melting characteristics of steel wool asphalt mixture was analyzed. A prediction model of the ice-melting rate of steel wool asphalt mixture based on a double-hidden layer backpropagation (BP) neural network was established. The results show that the road performance of the asphalt mixture mixed with steel wool mostly meets the requirements of the specification. The increase in steel wool content and length can improve the road performance to a certain extent. In terms of ice-melting performance, the content and length of steel wool have a beneficial effect on the ice-melting rate. The lower the ambient temperature or the thicker the ice layer, the slower the ice-melting rate. The greater the heating intensity, the faster the ice-melting rate. The average absolute error of the melting ice prediction model is 0.016, so the melting ice effect can be well predicted by this model.
