Crushed Portland Cement Concrete used as Flexible Base
Crushed Portland Cement Concrete used as Flexible Base
(OP)
Does anyone have some data/comments (firsthand) on the performance of CPCC
used as flexible base? Preferably with only a chip seal as the final riding surface.
Thanks

RE: Crushed Portland Cement Concrete used as Flexible Base
When hot mix asphalt is used over it, be sure you prime and tack...but expect some reflective cracking as it ages. The crushed concrete will "re-heal" with some unreacted cement, thus you will have a semi-rigid base with a flexible pavement surface...still works great though...certainly no worse with reflective cracking than soil-cement base and in my experience you have fewer cracks.
