“…And the deformation of the pavement was monitored by a deflectometer, and the results showed that the recycled aggregates from construction waste could be an alternative material in the unpaved rural road without risk of environmental pollution. rough the model test, Delongui et al [27] studied the strength and the stressstrain characteristics of the recycled aggregate to obtain pavement design parameters. e test results illustrated that the approximate elastic response was in the recycled aggregate.…”

In order to clear the shear mechanism of the scrap tire strips reinforced brick powder, a series of large-scale direct shear tests were carried out on the pure brick powder and reinforced brick powder. The scrap tire strips with 50 mm in length, 5 mm in thickness, and 10 mm, 30 mm, and 50 mm in width were put into the brick powder with volume percentages of 2%, 6%, and 10% as reinforcement, respectively. The results show that the internal friction angle and cohesion increase by adding scrap tire strips into brick powder. The peak shear strength of reinforced brick powder initially decreases, thereafter increases and finally decreases with the increase of volume percentage of the scrap tire strips. And the peak shear strength increases in the initial stage and then decreases with the increase of the scrap tire strips dimension. The optimal dimension and volume percentage of the scrap tire strips are 50 mm × 30 mm × 5 mm and 6%, respectively. In addition, the scrap tire strips provide constraints to restrict the vertical displacement of integral reinforced brick powder, and relative to the pure brick powder, the larger the vertical load is, the greater the decrease of vertical displacement is.

“…The results encouraged the use of C and D aggregates as an alternative for pavement construction. Delongui et al (2018) investigated the use of C and D waste parameters in pavement design. Tests showed that C and D waste presents good elastic strain and resilience modulus behavior compared to densely graded crushed basalt (DGCB).…”

The rate at which the construction industry explores and consumes non-renewable natural aggregates and other industrial products such as bitumen, lime, and cement during construction and rehabilitation of road pavements has over time proven to be environmentally degrading and non-sustainable. This, alongside the issues of high solid waste generation and inadequate disposal, has led to series of studies by various researchers to find methods to integrate these solid wastes as alternative materials in road construction and maintenance. This paper provides a simple yet detailed review of recent relevant studies conducted to understand the alarming rate of generation and the effects of reusing these waste materials in both flexible and rigid pavements. The review further outlines the advantages and disadvantages of the selected waste materials and compare the results with that of conventional materials in accordance with relevant standards while highlighting the performance, and life cycle environmental and economic sustainability implications. The study shows that the adoption of these materials offers efficiency in waste disposal while reducing the demand for natural aggregates and consequently, significantly reducing life cycle impacts and costs. The challenges limiting the effective practical implementation of these waste recycling techniques in the construction industry were discussed and possible solutions were suggested to encourage and ensure its utilization in road construction.

“…The authors concluded that the strength for the mix containing RAP was more than the other mix. Delongui et al [20] performed a research on using construction and demolition wastes (C&DW) on the basis of resilient modulus using Everstress layered elastic analysis software, shear strength analysis and on the outcomes of permanent deformation based on repeated loading. The results of their study suggested that the shear parameters of C&DW such as effective friction angle and its cohesive intercept are fairly analogous to that of Densely Crushed Graded Basalt (DCGB).…”

of the naturally available soil was studied for the rural roads in Karad. The California bearing ratio test analysis and their outcomes were employed to assess the strength of the subgrade in the study area. Further, based on the suitability of identified wastes in bituminous layer, IITPave software was used to analyze the performance of rural roads of the study area. Using the IITPave software, design charts were created based on utilizing the wastes for rural roads in Karad, District -Satara, India.
