Stancombe Quarry Car Park, Bristol

One of the earliest UK trials of a porous asphalt pavement took place on Tarmac’s Stancombe Quarry car park in 1999. This porous pavement continues to perform well both structurally and hydraulically.


Pervious pavements may require cleaning to maintain hydraulic conductivity. The frequency of cleaning will be dictated by site conditions. Tarmac’s quarry car park has been cleaned once since installation restoring much of the lost conductivity caused by clogging.
