“…The more influential side loading gives a higher deflection result than the center loading. Another study suggests placing flexible pavement over rigid pavement to mitigate the harm that rigid pavement causes [20]. However, the sort of injury that occurred was not particularly mentioned in this study.…”

This research was conducted on the Surakarta-Gemolong-Geyer road, which is suspected to be built on expansive land. Every day, this road is always passed by large vehicles, so it is feared that it will be easily damaged if it is not routinely carried out maintenance. This study aims to analyze the damage to the rigid pavement on the highway using ATENA 3D software. The damage analyzed in this study is the deflection. The factors that make the crack large and wide were added to the heavy vehicle load and swelling. The swelling test on the soil carried out in the laboratory was 37 kPa. The results obtained after analysis with 3D ATENA showed differences in deflection at each loading variation. The variation of the middle loading with swelling pressure has a value of -15.49 mm; without swelling pressure, it is -16.37 mm. The middle loading variation with swelling and without pressure has a value of -15.33 mm and -12.4 mm, respectively. Corner loading variation with swelling and without pressure has a maximum deflection of 1.28 mm and -0.26 mm, respectively. This research can be used as a reference and prediction in identifying cracks that occur so that the government can carry out maintenance and rehabilitation before the road is damaged.

“…Nano-dispersed materials, such as nano-carbon tubes, have a positive effect on the rheological properties of cement systems. Their particles, being distributed in the total volume of the cement dispersion, entering into a chemical reaction, together with larger particles create a spatial threedimensional framework consisting of chains and aggregates with versatile coagulation bonds [20]. In this case, the rheological properties can change cardinally: the coefficient of structural and plastic viscosity, cohesion and thixotropic characteristics of enriched solutions increase, and directly, as a result of physical and chemical reactions occurring during the arrangement of the necessary mixture, the strengthening of interconnected interactions.…”

The purpose of research work should be considered the practical aspects study of environmental pollution near highways with dust particles generated during repair work. The results of the study reflect the entire scope of research work carried out in order to determine the optimal composition of the concrete mixture for road repair work, which makes it possible to achieve a reduction in the emission of dust particles into the roadside environment and improve the environmental situation in the roadside. Also in this study, recommendations were proposed for the elimination of polluting factors and the elimination of negative consequences for the environment. The results and conclusions of this scientific study are of significant practical importance for road maintenance workers who professionally solve the issues of pavement repair, as well as for researchers conducting scientific research in the direction of studying environmental safety problems during road repair work.

“…The results of all the tests were calculated as the arithmetic mean of the values obtained in three different specimens. Traditional concrete for rigid pavements usually presents an intermediate or low workability, so it generally never reaches an S4 slump class (slump between 160 and 210 mm) [33]. Therefore, all the mixes had an adequate workability for a concrete of those characteristics, which was set as an objective during the design of the mixes (see Section 2.2).…”

Preliminary Validation of Steel Slag-Aggregate Concrete for Rigid Pavements: A Full-Scale Study

The high wear resistance and toughness of electric arc furnace slag (EAFS) means that this industrial by-product can successfully replace natural aggregate in hydraulic or bituminous concretes that withstand vehicle traffic. This article validates the use of concrete made with large amounts of EAFS for rigid pavements. Accordingly, three EAFS–concrete mixes made with metallic or synthetic fibers were designed. Their performance was studied through laboratory tests (compressive strength, modulus of elasticity, splitting tensile strength, and abrasion resistance) and field observations on full-scale slabs made with each of the studied mixes. All mechanical properties yielded adequate results for concrete for rigid pavements. The metallic fibers increased the strength and elastic stiffness by 7–10%, while the addition of synthetic fibers slowed the development of these properties over time. On the other hand, all the mixes allowed for a successful implementation of full-scale slabs, with none of them showing excessive deterioration after five years of exposure to the outdoor environment. Only minor cracking and some chips in the surface-treatment layer were detected. The strength development of the slabs and their slipperiness were adequate for use in high-speed pavements. The overall analysis of the results shows that concrete made with EAFS can be used in real rigid pavements.
