“…A few case studies also confirmed that the application of PCMs to structural members can bring a positive effect to the structural performance of repaired RC structures [13][14][15]. Ahmad et al [13] studied the possibility of using PCMs containing an organic film-forming re-dispersive polymeric powder produced in Pakistan for repairing cracks that occurred on the surface of RC beams.…”

“…The PCM specimens were cast with a cement-fine aggregate ratio of 0.5, a water-cement ratio of 0.4, and a polymer-cement ratio of 0 or 0.03. The amount of water was determined based on previous studies [14]. The substrate concrete specimens were prepared with a cement content of 340 kg/m 3 and a water-cement ratio of 0.24 to produce a high strength based on the result of previous research [20].…”

“…It is known that adding a polymeric compound to a cementitious material can improve the material properties such as strength, durability, and interfacial bond between the newly applied material and the existing substrate [1][2][3][4][5][6][7][8][9][10][11][12]. Therefore, incorporating polymers in patch repair cement mortars is common for better repair work of various reinforced concrete (RC) structures, including bridges, dams, high-rise buildings, pavements, and marine concrete structures [13][14][15][16][17][18][19][20][21]. There exist a few representative types of polymers, including acrylate polymers (AC), polyvinyl alcohol (PVA), styrene-butadiene rubber (SBR), and ethylene-vinyl acetate (EVA), all of which are utilized in the repair or surface treatment of RC structures.…”

“…The authors reported that the repaired specimens showed an equivalent or higher load-carrying capacity under the same load condition. Chen and Won [14] reported the results of a long-term investigation on patch-repaired concrete pavement structures with a focus on the interfacial bond between the PCM and the existing substrate. Specifically, the authors investigated three commercial products (FastPatch DPR (Willamette Valley Company, Eugene, OR, USA), SILSPEC FLEXPATCH (Silicone Specialties Inc., Tulsa, OK, USA), and Sikadur-72 JNS (Sika, Lyndhurst, NJ, USA)) in the study.…”

Chen and Won [14] concluded that the use of both polymer and fiber was effective for the longer service life of structures while reducing spalling and cracks. Kim et al [15] confirmed that the high bond strength of applied PCMs could contribute to improved cracking resistance by sustaining a higher maximum load.…”

This is an experimental study showing the effect of four types of polymers (acrylate polymer (AC), polyvinyl alcohol (PVA), styrene–butadiene rubber (SBR), and ethylene-vinyl acetate (EVA)) on the mechanical properties of polymer-modified cement mortars (PCMs). One polymer dosage was used in this study (3%), and the effect of this dosage on PCMs was compared with a control mortar mix with 0% polymer. The compressive, flexural, and pull-off bond strengths were measured and compared with previous results in works of literature. The effect of polymer addition on improving the mechanical properties of PCMs was clarified, and this effect was more obvious on the flexural strength than that on the compressive strength. The PCMs containing EVA showed the best performance, with up to 33% and 63% increases in compressive and flexural strengths after 28 days, respectively. In comparison, AC, PVA, and SBR produced smaller (16%–46% compared to control) improvements in the flexural strength after 28 days. In general, PCMs containing EVA showed the best mechanical properties.

Potholes are one of the most common road distresses in Kuwait especially after winter season in 2018. Pavement deterioration rate significantly increases as the pavement exposes to moisture. Paving road requires using high-quality materials. This paper aims to investigate the feasibility of using recycled asphalt pavement in hot mix asphalt (HMA) design. Questionnaires and a series of laboratory tests were conducted to analyze the effects of pores on the society and test the recycled and the regular mixtures performance to choose the best option regarding it. Marshal test portrayed that the recycled mixture has a high stability and flow. According to the tensile strength ratio test requirements which set a minimum ratio of 75%, it is recommended to reduce the proportion of recycled aggregate. The Hamburg wheel tracker (HWTD) test proved that the recycled asphalt mixture has a low rutting depth for wet and dry samples compared to the general one. On the other hand, the wet recycled mixture requires a reduction by of 20% to satisfy the specifications. The physical properties for both mixtures were compared, and the voids filled with asphalt (VFA) and voids in mineral aggregate (VMA) of the recycled mixture are lower than those in the regular mixture. The recycled mixture reveals a higher efficiency in saving costs and improving mixtures used for potholes maintenance activities. All the results proved that the mixtures consisting of recycled asphalt are most preferred since they are affordable and perform reasonably well compared to mixtures made of regular asphalt. As a future work, smaller percentages of recycled aggregate should be tested to check the robustness and sustainability of the designed recycled asphalt mixture using different tests such as Hamburg wheel tracker test (wet samples) and indirect tensile strength test. Furthermore, more experiments can be run to test other mix parameters and properties such as durability.
