| Summary: | Fundamentally, sustainability and cost-effectiveness in infrastructure development have received
widespread attention. Permeable pavement is such a concept that it is sustainable in the field of
transportation and is being tested. Fully permeable pavement is a modern design method in which
each layer is porous and can store water, avoiding the impact of stormwater on the pavement to avoid
stormwater, skidding, floods, and water splash on the road and parking area which decrease safety
rate. Porous asphalt (PA) is an asphalt mixture with a little or no fine aggregate. Due to open structures
and advantages are used as a drainage layer in highway pavements in reducing noise and decreasing
safety hazards during rainfall. Besides, it reduces splash and spray effects and thus increases the
visibility. The main aim of this study is to analyze the influence of two asphalt modifier types: Styrene
butadiene styrene (SBS) and propylene modifier polypropylene (PP), on porous hot asphalt mixture
performance. The PA evaluation influence findings are based on permeability, durability, and Marshall
stability-flow for hot asphalt mixture. The test results emphasize the modifier usage in reducing the
abrasion loss and increasing the stability with enhancing the durability of PA. PA mixture binder prepared
with 4% SBS and 4% PP modifier was the most polymer binder in modifying the abrasion resistance
and stability of mixture in pavements. |
