“…Ricci and Balbo [25] observed MDD in RCC that showed decreasing CDW trends when the percent of CDW increased. Due to the particularity of bitumen in particles, the RAP also tends to decrease MDD in RCC and increases moisture content as its percentage in mixture increases [26,44]. Thus, these results confirm the hypothesis on the increasing percentage of RA in mixtures, as the MDD decreases, and then the moisture content increases.…”

This research aimed to investigate the mechanical and physical properties of Roller Compacted Concrete (RCC) used with Recycled Concrete Aggregate (RCA) as a replacement for natural coarse aggregate. The maximum dry density method was adopted to prepare RCC mixtures with 200 kg/m³ of cement content and coarse natural aggregates in the concrete mixture. Four RCC mixtures were produced from different RCA incorporation ratios (0%, 5%, 15%, and 30%). The compaction test, compressive strength, splitting tensile strength, flexural tensile strength, and modulus of elasticity, porosity, density, and water absorption tests were performed to analyze the mechanical and physical properties of the mixtures. One-way Analysis of Variance (ANOVA) was used to identify the influences of RCA on RCC’s mechanical properties. As RCA increased in mixtures, some mechanical properties were observed to decrease, such as modulus of elasticity, but the same was not observed in the splitting tensile strength. All RCCs displayed compressive strength greater than 15.0 MPa at 28 days, splitting tensile strength above 1.9 MPa, flexural tensile strength above 2.9 MPa, and modulus of elasticity above 19.0 GPa. According to Brazilian standards, the RCA added to RCC could be used for base layers.

“…According to Figure 3, it is observed that coarse recycled materials are similar to large natural materials. This result was confirmed by other researchers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…As it seems, the tensile strength (RCC) with 100% of the material (RAP) is reduced by about 26% compared with control concrete (RCC0 / 0). According to other results [4][5][6][7][8][9][10][11], the tensile strength is not more than 2.5 Mega PPS in 28 days. Other researchers found that the reduction in tensile strength was approximately 56%.…”

One of the issues and problems of today's world is the massive amount of debris and trashes, especially asphalts resulting from the removal of worn-out pavements of urban roads. Recycled asphalt crumbs (RAP) are waste materials that certainly have significant undesirable effects on the surrounding environment. Given the properties reported by these materials, there are various ways to reuse these materials. One of the applications that has been considered by researchers is the use of these materials in cement mixtures, including concrete production. This is while a large amount of asphalt fragment is continuously produced in the repair and maintenance of roads. It is therefore desirable to be used in conventional mixtures used in construction of road pavements. In this regard, the present study investigates the use of recyclable asphalt materials in pavement roller shuttle (RCC) with the aim of reducing waste and its negative impacts on the environment. By examining the documentation and performing numerous experiments, it has been found that roller concrete made from recycled asphalt can be used as a suitable pavement for low traffic and rural roads, as well as for the final covering of a wide range of sidewalks.

“…As can be seen from Figure 8, the elastic modulus at 28 days of age of all RCCP mixtures in this study was in the range of 30 GPa to 36 GPa. This range of values is found to be similar to that of conventional RCCP provided by a number of former scholars [28,33,34]. Therefore, the delay in compaction slightly affected the elastic modulus of RCCP.…”

This study investigates the effect of delay in compaction on the optimum moisture content and the mechanical propertie s (i.e., compressive strength, ultrasonic pulse velocity, splitting tensile strength, and modulus of elasticity) of roller-compacted concrete pavement (RCCP) made of electric arc furnace (EAF) slag aggregate. EAF slag with size in the range of 4.75-19 mm was used to replace natural coarse aggregate in RCCP mixtures. A new mixing method was proposed for RCCP using EAF slag aggregate. The optimum moisture content of RCCP mixtures in this study was determined by a soil compaction method. The Proctor test assessed the optimum moisture content of mixtures at various time after mixing completion (i.e., 0, 15, 30, 60, and 90 min). Then, the effect of delay in compaction on the mechanical properties of RCCP mixtures at 28 days of age containing EAF slag aggregate was studied. The results presented that the negative effect on water content in the mixture caused by the higher water absorption characteristic of EAF slag was mitigated by the new mixing method. The optimum water content and maximum dry density of RCCP experience almost no effect from the delay in compaction. The compressive strength and splitting tensile strength of RCCP using EAF slag aggregate fulfilled the strength requirements for pavement with 90 min of delay in compaction.
