Question

there is an exisitng temporary asphalt paved road and can we use this as a sub-grade for constructing a new asphalt paved road on top

Answer 1

If it was a "temporary" road to start with, I wouldn't bet on it having a proper sub-grade to start with, a thin layer of asphalt on an improperly prepared surface will not be a particularly good base for a new pavement. You need to check with the the engineer who built the road the first time.



It may be possible to recycle the existing road as, or part of, the new sub-grade, take a look at this:
