Abstract
Nablus city faces many problems related to water especially in the winter, these problems
include flooding, accidents, and hassling the pedestrians. In addition to that, ground water is
limited, runoff flow is being wasted, and the citizens of the city don’t have access to clean
water all the time. Therefore, the solution for this was to somehow increase the accessed ground
water, this was done by using a permeable paving system, more specifically, the porous asphalt.
To achieve this, a porous asphalt design was made and a feasibility study was done to see
whether the economic and environmental aspects for porous asphalt add any benefits or harms
compared to the conventional asphalt design. By the end of the study, it was concluded that
economically, the porous asphalt paving system saved up to 1,912,000 ILS for the return period
of the study which is 20 years compared to the conventional design. As for the environmental
aspect, it was concluded that if the conventional pavement is replaced by the porous asphalt,
the groundwater could be recharged at a rate of 107,404.7 m3
/year. In other words, 37,023,350
ILS per year can be saved for the government which can satisfy the capita of the city for around
7 days
