Bangalore tar roads were/are bad. It needed to be tarred twice a year. The tarring process was/is bad. The white topping was the silver bullet solution to this BBMP-contractor tar nexus. It is claimed white-topping is 5 times more expensive than tarring. So if the white-topped roads hold good for 5+ years, then it will break-even. Quote:
Tendersure also was a good initiative. Looks like that also now scaled back or scrapped altogether.

Bangalore CBD area is pleasant to walk because of TenderSure footpaths. It is a pity that this amenity was not extended to other parts of the city. Quote:

1. Tarred roads allow water to seep through to the ground and it helps refill ground water levels. The concrete that is used for this white topping doesn't allow that. All the rain water goes down the drains and wasted. Depleting ground water levels are a hard hitting reality in Bangalore (ask any body who got borewells drilled and how deeper and deeper they're forced to go with each passing year). |
Tarred roads allowing water seepage like soil is news to me. Tar allows water seepage but takes weeks. Tarred roads develop potholes because of water seepage. Hollow dents on-road hold water for a long time and then tar breaks, potholes are formed.
Potholes are not the mechanism for groundwater harvesting. Roads occupy a small percentage of the city area and rainwater on roads run into storm drains. Water from storm drains can still be collected and water harvesting can be performed by concerned citizens. Quote:
2. Because of reason 1., old roadside trees which Bangalore was once famous for are dying a slow death because they aren't getting enough water. that is if they are already not cut down. this definitely is taking the temperatures of the city higher
|
Roadside trees are decreasing because new trees not planted on roads. Neither the existing ones are watered. Road widening, metro construction has affected roadside trees cultivation. Quote:
3. Many of these new white-topped roads already have already turned smooth and pose a high risk of vehicle skidding(especially 2-wheelers). They may last long in terms of not getting potholes, but they don't last long with respect to surface roughness.
4. If re-tarring was a scam as per you, re-scaling (lines to keep the surface rough will replace that). I'd prefer the former because re-scaling or repairing dug up sections of White topping is tougher and more expensive that re-tarring (digging up new roads isn't stopping anytime soon).
5. Tyre life of our cars reduce drastically with concrete roads...the cascading effect because of this is also a real issue.
|
Not such pain-points to avoid concrete roads. Quote:
6. The roads selected for white topping are already good wide roads with hardly any issues (like in and around Lalbagh, KR road). The roads which were bad earlier, remain bad. Priority is something that our city planners don't know.
|
True. Hope they select heavy vehicle traffic roads because those are prone to damage. First in my list would be Bannerghatta road. Quote:

Similarly for flyover project from Chanlukya to Hebbal. People opposed and it was dropped. Now, people have to face slow-moving traffic daily. There was no alternative plan proposed to decongest the area. Quote:

If it is the usual BBMP quality, all of it is down the drain. |
Pilot was done in 2011 from St John Hospital signal till Madivala underpass. Isn't the cost around 1000 crores for 90Km, which is around 150 million USD?
IISc profs want many good things in life like walking cities, cycle lanes, pedestrian thoroughfares, parking lots converted to sitting areas, vertical gardens. These are good 'self-actualization' ideas and doesn't seem mean much to the hapless citizens of this city who are stuck in traffic and struggling for their 'physiological' and 'safety' commute needs.

Truly the benchmark on how not to make concrete roads ! |
That's true. It was sponsored by cement lobby. They wanted to demo concrete roads but made a poor surface. Need a vehicle with good suspension so as to not to notice the road undulations. All underpasses have concretized roads (but with poor drainage). In Madiwala underpass, I think they were trying tar mats, for reasons unknown.
