Colloidal stability of eco-friendly sustainable asphalt binder prepared
using different waste polymers for different climates
E
co-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.
