Waste materials in highway applications: An overview on generation and utilization implications on sustainability

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