Bangalore, on the ground

[ How not to repair a potholed road. 


Deepen and widen all potholes using a bulldozer to about half a foot deep and as wide as half the road. 

Fill it with stones/gravel and mud (local red soil) and lightly roll it.

Pretend road is repaired. Atleast, it looks better than what it was. 

Wait for one rain and one truck to go over it. Progressively, it will get even worse! Heres how the said road looked after one rain.  It got progressively worse, like cavities in teeth do. Once you drill, it only gets worse. ] This was a week before elections in Karnataka.

Now, in about a month after the new government has come on board, this road has been repaired. Before you think "expressway" - let me qualify. These above mentioned repairs have been done up with asphalt, rollers and looks pretty much a real road. Quite a few other internal but important roads have also been tarred. 

I read somewhere that the first 100 days in office are quite important for a government, so this government based entirely on the places I cover in Bangalore (quite limited) seems to have its heart and mind in the right place...

It's kind of interesting to see how pothole "evolves". Evolution of pothole in road is not too different from evolution of a crack in solid material.
1. Pothole is created by road maintenance activities. Some gravel gets loose as a result of that.
2. The gravel gets rubbed on the leading edge of the pothole by vehicle tires.
3. The pothole expands in that direction.
4. The expanding pothole creates more loose gravel and pebbles.
5. step 2. repeats and so on.

If we just clear the loose gravel on the road periodically, would it help to slow down the growth?
