Water stays on AC pavement
Water stays on AC pavement
(OP)
Hello all,
I am in charge of a paving project using standard 1/2" PG-64-10 Caltrans AC mix. The latest area was paved a couple hours before a rain event. This area is now uniformly covered with small puddles of water that doesn't drain off. The grades are around 1% and other areas of the project shows water draining off.
The only theory I have is that the oils from the curing, freshly paved asphalt mixed with the water and therefore it doesn't drain off.
Has anyone had similar experiences? Could I be correct regarding the oil or is there some other explanation?
Thanks,

I doubt the theory of mixing oil with water. They simply don't mix with each other. Use a smart level to check the area where water stay to make sure it has the required slopes.

Examination of the grades have shown that this was not a case of "bird baths".
Subsequent rain events have not yielded the same phenomenon, so I tend to believe that it was caused by the clean virgin asphalt that was still curing.
