“…Considering the economy of engineering, the recommended thickness of the asphalt layer is 8 cm~12 cm. These results are similar to those found in the studies by Fardin and Santos [18] and Fang et al [29].…”

“…The results indicated that the asphalt overlayer reduced the temperature gradient within the CRC layer. Fardin and Santos [18] evaluated the effects of pavement design variables on fatigue cracking and rutting resistance, and asphalt layer thickness had the biggest impact on reducing damage. Xie and Wang [19] analyzed the effect of thermal cycles on reflective cracking in composite pavement; the results showed that a thicker asphalt overlayer significantly decreased the reflective cracking potential at the crack initiation phase.…”

Based on thermal–mechanical coupling simulation analysis and physical engineering tracking observation, the mechanical behavior and response of a continuously reinforced concrete and asphalt concrete (CRC + AC) composite pavement layer were analyzed, and the causes of cracking on the surface and bottom of the asphalt layer were revealed. Studies have shown that under normal driving conditions, the AC layer, which is usually in the position of the wheel load gap and wheel load side, more easily generates a longitudinal “corresponding crack”. Compared to normal driving, longitudinal cracks are generated more easily inside of the curve, and transverse cracks occur more easily on poor stadia curves. When the AC layer thickness is less than 8 cm, the AC layer is more prone to bottom-up cracking, and it is more prone to top-down cracking when it is more than 8 cm thick. Comprehensively considering the tensile stress, shear stress, and the thickness of the AC layer, it is recommended that the suitable thickness range of the AC layer is 8 cm~14 cm. The calculated results show good agreement with the physical engineering investigation. The research results can provide a theoretical and scientific basis for cracking control and the rational design of a CRC + AC composite pavement layer.

“…According to previous studies [163][164][165][166], RCA is directly applied to various ment layers, such as the surface, subgrade, and base, as well as rigid pavements [167 In addition to treatment efficiency, RCA's treatment cost and environmental impact are important for its wide-scale application [148][149][150]. The use of RCA as an alternative to NA in the manufacturing of concrete can alleviate the environmental impact of the extraction of NA resources, carbon emissions, and greenhouse-gas emissions [17,34,[36][37][38]151].…”

In the construction industry, natural aggregates (NA) can be replaced by recycled concrete aggregates (RCA), which can address the issue of construction-waste disposal and resolve the dilemma between demand and supply. This paper aims to systematically review the modification of RCA techniques and their application in producing recycled aggregate concrete (RAC). First, the pretreatment approaches for enhancing the properties of RCA are introduced. Next, the improved efficiency of these approaches and their influences on the workability, mechanical strengths, and permeability of RAC are analyzed and discussed. Subsequently, the effectiveness of different techniques and their cost/environmental impact are compared. Finally, some case studies of the application of RCA in infrastructure are presented, and the remaining challenges and perspectives are discussed. The results of this review work can extend the knowledge of RCA and RAC, as well as serving as a source of inspiration for further studies.

“…Once the defects appear, they provide a channel for the corrosive medium, aggravate the failure of the concrete, and seriously reduce the service quality of the pavement [ 2 , 3 , 4 ]. Excavating and re-paving the damaged road surface inevitably causes a waste of manpower and material resources as well as an inconvenience to open traffic and fast navigation [ 5 , 6 ]. Therefore, it is an urgent problem to repair concrete pavement quickly and efficiently.…”

Concrete surface defects are very complex and diverse, which is a great test for repair materials. The efficiency and durability of the repair system depend on the bonding effect between the concrete and the repair material. However, the rapid increase in system viscosity during the reaction of repair materials is an important factor affecting the infiltration effect. In the present work, the infiltration consolidation repair material was prepared, and its basic properties (viscosity, surface drying time and actual drying time, infiltration property) and mechanical properties were evaluated. Finally, the infiltration depth, film-forming thickness, and anti-spalling ability of concrete under a single-side freeze–thaw cycle are revealed. The results showed that using ethyl acetate could rapidly reduce the viscosity of the repair material, and the repair material could penetrate 20–30 mm into the concrete within 10 min. It was found by laser confocal microscopy that the thickness of the film formation after 3 days was only 29 µm. In the mortar fracture repair test to evaluate the bond strength, the bond strength of the repaired material reached 9.18 MPa in 28 days, and the new fracture surface was in the mortar itself. In addition, the freeze–thaw cycle test was carried out on the composite specimens under salt solution to verify the compatibility of the designed repair material with the concrete substrate. The data showed that the average amount of spalling was only 1704.4 g/m2 when 10% ethyl acetate was added. The penetrating repair material in this study has good infiltration performance, which can penetrate a certain depth in the surface pores and form a high-performance consolidation body, forming a “rooted type” filling.
