“…Waste rubber has also been reutilized as additives in asphalt mixtures in the past few decades. From the environmental stand point, this alternative has been seen to be attractive, yet, it has not been extensively adopted because its implications on road life cycle cost and performance have not been conclusively established (Ganiron, 2014). The two different techniques adopted in incorporating these wastes are: 1) the wet process and 2) the dry process (Rodríguez-Fern andez et al, 2020;Tahami et al, 2019).…”

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.

“…A scalping screen will remove dirt and foreign particles. A fine harp deck screen will remove fine material from coarse aggregate [12,13]. Further cleaning is necessary to ensure the recycled concrete product is free of dirt, clay, wood, plastic and organic materials.…”

“…In Europe, Canada, and Japan, concrete recycling is regulated and often mandated. In particular, Germany promulgated the national setting the guidelines for recycled concrete content in concrete aggregate [12]. German researchers demonstrated that recycled aggregate does not affect most performance characteristics of concrete, although it tends to increase drying shrinkage and creep, and reduce modulus of elasticity [11,12].…”

Recycling of concrete debris can make a contribution to reduce the total environmental impact of the building sector. To increase the scope for recycling in the future, aspects of recycling have to be included in the design phase. Besides, aggregate sources near Metro Manila are almost depleted, so aggregates have to be brought from far quarries. Consequently, reclaiming aggregates from concrete debris would lead to environmental and economic benefits. This experimental study aimed to use crushed concrete debris as alternative fine aggregate in a mortar mixture. A conventional mortar mixture will be compared to concrete debris mixture of the same proportions.

Abstract. Road surface is designed to be the durable surface material to sustain the traffic loading. However, due to physical and mechanical stress, pavement deterioration is accelerated. Thus, modifying conventional bitumen by improving its properties is seen as the best method to prolong pavement in-service life. The purpose of this paper is to study the effect of waste natural rubber (NR) latex on rheological properties of bitumen. Conventional bitumen PEN 80/100 was modified with different content of waste NR latex using a high shear mixer at temperature of 150°C. The modified binder properties were characterized by conducting physical test (i.e. softening point, penetration and penetration index) and rheological test (i.e. dynamic shear rheometer, DSR). Results showed that, the addition of waste NR latex improved the rheology properties, which indicates by improving of rutting factor (G*/sin δ). This properties improvement has also shows a potential to resist deformation on road surface despite of high traffic loading.
