  • Elucidation of Asphalt Characteristics Influencing Cement Mortar Constituted with Reclaimed Asphalt Pavement Aggregates
    Bibhuti Bhushan Bhardwaj, Surender Singh
    Journal of Materials in Civil Engineering, 2026
    This study elucidates the role of asphalt binder coating of the reclaimed asphalt pavement (RAP) aggregates on the behavior of cement mortar. To fundamentally understand the role of asphalt binder, the fine RAP aggregates were prepared in the laboratory, varying the asphalt binder characteristics such as viscosity [100–400 Pa.s (1,000–4,000 Poise)], its content (film thickness of 6 and 8 μm), and aging intensity (short- and long-term). A direct correlation was found to exist between asphalt cohesive strength and mortar performance. Specifically, long-term aged binders were found to enhance the flexural strength by 3%–4%; upgrading binder grade from VG-10 to VG-40 increased the same by 19% while increasing film thickness from 6 μm to 8 μm decreased the strength by 16%. This study suggests that RAP derived from older pavements or those utilizing a stiffer asphalt binder yields enhanced concrete strength, in contrast to RAP from younger pavements or those with a softer asphalt binder.

    Transportation Research Record, 2026
    The complete segregation of bricks from construction and demolition waste is quite challenging, leading to a reduction in the quality and suitability of recycled concrete aggregates (RCA) for rigid pavement applications. This investigation fundamentally studied the effect of brick waste (BW) on the performance of pavement quality concrete (PQC) made with RCA with the aim of identifying the tolerance limit of different BW fractions (coarse and fine) in RCA. This was achieved by mapping the fresh and hardened state behavior of PQC as well as mortar post-inclusion of BW fractions (0%–30%). Contrary to the general perception, the intermixing of BW in RCA was found to be beneficial, as it overcomes the negative effects of hydrated cement mortar paste present in RCA. The presence of BW in RCA resulted in 9%–36%, 15%–25%, and 5%–17% increases in the workability, compressive strength, and modulus of rupture of PQC, respectively. These increases have been attributed to the better morphology of BW compared with RCA and natural aggregates. In addition, BW possesses some pozzolanic reactivity, which facilitates chemical bonding between the aggregate surface and surrounding mortar paste. In fact, BW grains were found to retain moisture, leading to a reduction in the drying shrinkage of PQC by 54%–115%. Based on this study, the presence of 10%–15% BW in RCA could be considered as a threshold limit.

  • Suitability Assessment of Alternative Sands for Concrete Pavement Applications
    Bibhuti Bhushan Bhardwaj, Surender Singh, Bukke Pote Naik
    Journal of Materials in Civil Engineering, 2024
    In this investigation, four types of sands as alternatives to river sand, namely, crushed sand (CS), marine sand, fine recycled concrete aggregate (FRCA), and fine reclaimed asphalt pavement (FRAP), were studied for their potential for cement-concrete pavement applications. Initially, the physicochemical and morphological characteristics of these sands were understood and later linked to the hydration kinetics and the behavior of cement-mortar systems in both the fresh and hardened states. Due to their evenly graded particle size distribution, CS and FRCA exhibited higher packing densities despite having more gradient angularity, whereas the interlocking capacity of FRAP was found to be affected by the agglomerated particles. Morphology, fineness modulus, and chemical composition of the sands were observed to be the dominating parameters affecting the hydration kinetics and thus the performance of the mortar mixes. Improving these parameters, especially the grain size distribution, could help in enhancing the potential of these sands for pavement applications.

  • Optimization of Slurry Impregnation Technique for Upcycling Carbonated Recycled Concrete Aggregates for Paving Concrete Applications

    Journal of Materials in Civil Engineering, 2023
    Extraction of recycled concrete aggregates (RCA) from construction and demolition waste is an effective way to induce sustainability in the highway sector. However, inclusions of these inferior materials could significantly deteriorate the performance of paving quality concrete (PQC) due to the presence of old adhered mortar (AM) around the RCA. Numerous techniques are available in the literature that primarily address the issues with AM for increasing the potential of RCA for concrete applications. However, the energy demand and associated emissions are higher in most of these techniques, whereas carbonation and slurry impregnation (SM) techniques are regarded as the best ways to economically enhance the characteristic of RCA for large-scale applications. The present study is the first of its kind to optimize the SM process for carbonated RCA for PQC roads; RCA was stockpiled in the natural environment in loose condition for around 12–14 months for fully carbonating the Portlandite phase. The parameters optimized are slurry material type (silica fume, fly ash, and cement), their concentrations (20%−60%), exposure duration (4–12 h), and RCA sizes (20 mm and 10 mm), whereas the porosity, toughness, absorption, and dry density were considered for process optimization. Finally, for process validation, various PQC performance parameters (fresh, mechanical, and durability) were determined. The findings suggest soaking the RCA sizes in any of the considered cementitious/waste material slurry at 40% concentration for 6 h for enhanced performance of both RCA and PQC made with treated RCA.
