Interlocking tiles v/s concrete roads

Interlocking tiles means

1. more joins

2. poor ride quality

3. drainage problem

4. laying complexities(it is not as easy as construction of CC pavement)

5. Life of the pavement surface(due to non uniform sub-layer reaction)

Interlocking paver tiles are meant for ultility areas only and can not function on par with solid CC pavement.

Interlocking tiles can not be adopted for highways for simple reason that these tiles will  not give smooth and continous riding surface. Due to which speed and fuel efficiency of vehicles will suffer very badly. Due to joints drainage will also be problem. When these tiles are used in footpaths without proper base start setteling due to improper drainage.

I would like to support Mr. Ghosh that interlocking blocks will give a much rougher surface affecting ride quality and fuel economy of vehicles. So we must go for cement concrete roads.

Interlocking tiles/blocks are temporary solution........we must go for well designed concrete roads for permanent solution with adequate drainage system.............

I do not know the logic behind using interlocking tiles on NH, but to me it looks an inferior surfacing. For one, because of the inherent unevenness of the laying, this will give a much rougher surface affecting ride quality and fuel economy of vehicles. For another, due to the uneven surface, there could be water logging / accumulation on the surface, leading to hazardous driving conditions in the rain.

Agreeing Mr Ghosh I just want to add that construction of interlocking tiles is a slower process. So time should also be made a factor while deciding.

I agree with Ghosh sir actually rigid pavement are prefered in areas having weak subgrade since they have the capability to distribute the point load acting on their surface to the whole slab area.
