Rigid pavement - noise reduction
Rigid pavement - noise reduction
(OP)
We have designed a concrete slab for a highway and have to find a way to reduce noise due to traffic. The construction is scheduled for the 2002 summer.
Are there any techniques available for that purpose? For instance, if we add a flexible pavement on the concrete slab, what would be the minimun thinkness to avoid peeling?
Thank you very much for any suggestion,
Yours Truly

A couple of things can be done to mitigate the noise issue. One is to use continuously reinforced concrete with minimal joints. Another is to space the joints at different intervals. The spacing variation doesn't have to be great, just patterned with short, long, short, long, long, short, etc.
One other method is to skew the joints so that two tires don't hit the joint at the same time. Be aware that this method will require closer attention to load transfer design.
Good luck.

2. The minimum thickness of asphaltic mat is usually 3x the maximum aggregate size, 1.5 inch minimum. Thinner mat thicknesses have been tried in MI over the last 50 years. None are in still place.
