Pavement Replacement
Pavement Replacement
(OP)
I'm working on a job where we are redeveloping an existing gas station. Part of the scope is to replace all the asphalt on the job. This was due partly to the asphalt's condition, but mainly because I had to regrade the pavement to accomodate changes. I would like to avoid replacing the pavement full depth, meaning I would like to keep the base aggregate. What, if anything, should I be concerned about when reusing an existing base aggregate? My thinking is if we get a proctor on the material and make sure its compacted properly, we don't need to worry. I guess something makes me think you would need to remove it all or place it again.

You should be aware, however, that the recycled AB may not meet the specs of your DOT. Because this is just a parking lot/gas station (and depending on the attitude of the local building agency) you may be able to increase the pavement section of the recycled material compared to virgin material (which is likely to happen annway by using the AC volume). Or if need be run sieve, duribility, r-value ect. testing to show if the material is in spec.

As for pulverised granular material meeting a spec, it doesn't need to on a private project (as in this case). If a public project it is a different storey (maybe).
