Abstract
Asphalt production is reimagining with discarded materials like waste oils, plant-based
additives, and scrap wall paint as fillers in hot mix asphalt.
We found that plastic-based paints can be heated and mixed with bitumen, while enamel-based
paints can be melted to create filler materials. The paint scraps were collected from various
locations and ground to the necessary fineness for our study.
During the research, we treated different types of paint, including asphalt, with powdered paint
scrapings at varying replacement rates, alongside using stone dust as a control. Additionally,
we explored the potential of using fish scales as a filler material. Our findings showed a slight
increase in Marshall's stability due to powdered paint waste compared to the baseline. Notably,
stability values showed some improvement when bitumen was used with both paint types and
also Fish Scales.
Our study suggests that the use of paint-based filler and fish scale filler as a replacement for
traditional filler can lead to an equivalent increase in asphalt mix strength. However, it's
important to note that in some cases, this strength gain may be offset by increased moisture
resistance, despite promising economic results. Furthermore, it's crucial to consider that certain
paints may contain heavy or harmful materials
