Abstract:

The need to manage construction and demolition waste (CDW) and plastic waste (<30µ) has led to environmentally-friendly actions that promote the reuse and recycling of this type of waste and other forms of waste valorisation. The main priority is to foment sustainable construction work, which has the advantage of avoiding the deposit of large quantities of construction waste at landfills and greatly reducing the use of borrow material in construction projects. In this sense, the reuse of CDW materials significantly lessens the impact of construction work on the surrounding environment. The aim of this project work is to verify the technical viability of using construction waste and plastic waste (<30µ) as material for the base pavement layers of road surfaces. For this purpose, various tests were conducted on CDW aggregates and bitumen, for the determination of their various properties to check their suitability for use in base course. The proportioning of aggregates was done by trial and error method, and the proportioning of bitumen was done by Marshall Stability test. Strength of the mix with varied proportions of plastic was tested and the optimum plastic content giving maximum strength was found out. The results showed that there is satisfactory strength for the DBM base course constructed using CDW and there is further increase in strength and stability by the addition of plastic in the base course for road construction.
