Abstract

Eco-friendly and sustainable asphalt can be obtained using waste polymers recycled industry and cause severe environmental and climatic problems. In this paper, we studied the effect of waste polymers of different nature and different composition on the colloidal stability of environmentally friendly asphalt for application in different climatic environments. The waste high density polyethylene (WHDPE), waste poly propylene (WPP) and waste polystyrene (WPS) were added in 10% and 15% wt after their evaluation to study the effect on the colloidal stability of the asphalt formed using the chromatography column and HPLC for detecting SARA fraction of prepared modified asphalt. The results showed that the use of polymers of different nature leads to different results. Aliphatic polymers contribute to the increase of colloidal stability due to the increase of saturates and asphaltene, conversely, polymers of aromatic nature contribute to the decrease of colloidal stability due to increasing the proportion of aromatic in the mixture in line with solvent like as like. The research concludes by recommending the use of polymers of aromatic nature to improve asphalt specifications more in cold climates while aliphatic are used in hot climatic zones. This reduces costs and environment problems of waste polymers by using in the preparation of eco-friendly asphalt, according to the principles of sustainable development and climate change.
