POTHOLES' REPAIRS

Potholes’ Repair

The comments for not possible to repair the potholes by BMC officials are really pathetic and can only be accepted by persons not related to road engg.

The fundamentals of road engineering are not being followed for repairs of potholes which are distratous and prone to accidents. The everything for repairs are being done in most careless manners, may be by contract people, and not at all supervised by technically qualified staff.

As I have seen the ordinary workers fill up the potholes without being directed for the reliable procedure for repairs. No wonder that the repairs are unsuccessful.

For asphalt road repairs, affected by potholes, the surface must be cut by at least half foot more surrounding the repairs in a rectangular shape with asphalt cutter machine. Inside cut area, loose matter is required to be removed till sub-base. Then the subbase must be well compacted with compacting machine, for small area 1.5 to 2 tonne bomag roller would be better. For checking compaction, density test should be done by laboratory. The cutting edge of asphalt must be well cleaned to remove dust. Over the cleaned edge and sub-base hot bitumen must be applied as a binder, before filling the affected area with mixture of hot bitumen and road metal. Then after keeping required camber, the surface must be well compacted with compacting machine. Some of the big potholes are required to be checked with compaction test.

As far as I saw BMC’s method of repairs, they have never done the proper ways. They are repairing asphalt roads like earthen roads.

Then regarding repairs of paving block’s road repairs, nobody bothers for compaction of subbase, interlocking junction of existing blocks and compaction over the finished surface.

In no other countries the condition of roads can be found that we are having in our aamchi mumbai. Moreover we must be shameful to announce our unability to maintain the well conditioned roads..
