Road Drainage
Road Drainage
(OP)
The asphalt in the middle of a reverse crown road (center drains)wears out and develops potholes (erosion?) in too short time. Is there a solution or road modification to help this problem?

RE: Road Drainage
To deal with the existing problem, a proactive pavement management program is probably your best bet, sealing cracks as they occur, before water can enter and create potholes.
Considering the timing of your post, can I assume that this is a freeze-thaw problem?

RE: Road Drainage
Since the land is relatively flat, and the roads have a reverse crown, the water tends to collect in small pools at the roads center. Traffic passing through these wet spots evventually causes pot holes. The comment re how the lanes come together may be pointing to an additional cause. We're looking for some relatively inexpensive way to improve this situation.

1 - Dig a 2' x 6" deep trench in the center
2 - Line the trench with a rubber liner
3 - Add 4" of gravel
4 - Close the top with 2" of Flexi-Pave (an extremely porous sphalt substute).
This should effectively be a scupper leading to the center drains, and keeping tne roads dry.
Any comments, please post
Thanks
