Resumo
This study evaluated the performance of permeable pavements with coatings the type
Paver, Porous and Concregrama under different basic conditions in order to control runoff
at the source. Were simulated by means of a simulated rainfall, the rain event intensity
100.80 mm/h with a duration of 30 minutes and 64.20 mm/h for 60 minutes, on the floor
constructed in three different structural conditions. The stretch I with 15 cm storage layer,
the stretch II with 7 cm and the stretch III with only 4 cm. The tests were performed in
duplicate and all simulations were performed 36. The pavements were evaluated for the
generation runoff, storage and retention of the flow. The nine permeable pavements
evaluated in this study allowed a reduction of more than 50% of the runoff and the delay
on average 17 minutes runoff, as well as the temporary storage of rainwater. In terms of
coefficient C, the structure that presented the best hydrologic performance was the stretch
I, the results varied from 0 to 0.20. Only pavements with Paver coating showed runoff.
