Re: Interlocking blocks as a Road Extension - Your thoughts? 1.They are cheaper to install and maintain (in short term).
2.Longivity is not as much as concrete road so some of the cheap maintenance cost is offset.
3.Repairing is fast and easy as the contractors would only replace damaged blocks, unlike a tar road which requires extensive setup to repair properly.
4.Safety, its cheap at the cost of safety.
Advantage
1.Its repair friendly and usefull for road areas prone to frequent damage like the ones near watersupply, sewers manholes more of such stuff u can imagine.
2.The strip is used(or in future) for laying of other utilities like cables for street light or power distribution, water or drain lines below.
I personally donot like this stuff on roads. Good for paved areas around residential, commercial buildings, footpath and in parks. I have seen special design on walkways that have openings to allow rain water percolation. |
