Permeable roads allow rainwater to pass through into the ground. Rainwater percolates through the road’s layers.
This road design has a few structural advantages, including: reducing storm water runoff, reducing erosion, reducing the heat island effect, and filtering pollutants in the layers. They are also less costly; the costliest input in the interlocking road is the brick and this design uses almost half the quantity of bricks.
