hi curious, why certain roads cant last long. i read somewhere, a road supposedly can last 10 years. but nowadays, today u tampal the pothole, next week the hole reappears.
what is the reason?
also, i was there a pothole in the first place? is it the quality of work/tar? or the temperature of the day? or isit bcos the road not yet ready to be used yet they already open the road for usage (this could be bcos its a main road etc).
Depends on the base condition. If the base is soil of high water content then even if you design 20 years also the road will be damaged way faster due to the movements of the base.what is the reason?

The normal 'tar' type of road you usually seen is to allow ease of maintenance of the road.
Potholes come from variety of reasons, from wheel loadings to internal seepage. Opening a road for usage is rarely the cause, since wheels will usually compact the courses faster.
