Parking Pavement

[kxa]

I am working on an existing parking lot that is being used by a 40 unit apartment building. There is a dumpster at the end of the lot which the sanitation trucks drive to pickup trash and then back out of the parking. Severe wheel rut, settlement (8") and some unraveling of the 1.5" thick asphalt can be seen in the wheel path of the truck. Elsewhere the asphalt looks good for the age (minor cracks).

I was planning on replacing the asphalt with 1.5" of top course and install an 8" thick reinforced concrete slab in front of the dumpster (12'W x 30'L). The other option I was considering would be to use 2.5" of binder and 1.5" of top and no concrete slab. For both options, 4"-6" of RCA would be installed and compacted. The project is located in the northeast area and snow, ice and salting would be a concern.

I would appreciate any thoughts, suggestions or reference materials.
Thanks

I think concrete is a better way to go. Attached are some details for a concrete slab with wear plates. The details are from a facility that utilizes a large dumpster.
