Restoring Road Subbase with Full Depth Reclamation

[@aaronkuntze7494]

That's incredible!

[@DelawareT2Center]

Yep, it's a pretty good fix when you pick the right road.

[@aaronkuntze7494]

@@DelawareT2Center it saves hauling it off & hauling in new aggregate base, that's labor intensive..

[@jimmymckay73]

Where are the results ? Is there a part two ?

[@DelawareT2Center]

Part 2 in this case was a chip seal application - see kzbin.info/www/bejne/g5yyemyfo557g6s.

Where's the water in process? I don't see the water truck ahead of the rroad reclaimer.

Excellent question. My recollection is that there had been significant rainfall on the scarified material prior to placement of cement and homogenization. But they still would have come back after grading it to wet it again and then it would be necessary to wet daily for 4-7 days, depending upon the design. That's all a weasel's way of saying, oops, failed to get a shot at a water truck! See this project as well - kzbin.info/www/bejne/qnm1dpKCgp5jas0 - there you see the water truck included.

Many thanks.

C'est quoi le but du jeu ? Pourrir une route qui était propre, c'est cela ?!

I hope we have the translation correct. Seemed like you asked what was the goal or purpose. A good question. This road had become distressed beyond other pavement preservation methods (i.e., crack seal, microsurfacing) and had subsurface deficiencies. Simply milling and paving would have just put an expensive cover on a poor subbase. This techique re-homogenizes the existing asphalt and the drainage materials under it, mixes it with a small ration of cement and lots of water, creating a stronger foundation for a surface treatment. The result is a less expensive approach than removing all the material and replacing with virgin material. The road should be stable for many years to come and can be sustained with new surface treatment (probably chip seal followed by slurry seal) every 7-9 years. Merci pour la question.
