Repairing a concrete track

[dogsdangly]

Hi all

I live at the end of an 800m (3m wide) concrete farm track poured 30 years ago but now in a sorry state. Whilst large parts of it are reasonably ok (a little rough but no real pot holes) there are several badly potholed sections amounting to about half the track. There is still some farm traffic on the road along with the occassional truck. As far as I can tell there is no reinforcement - just very thick concrete.

I have read most of the site and have researched this on the net as much as I can but reckon I have only confused myself further!

As far as I can tell I have two options -
1. repair sections by cutting/ digging them out and pouring in new concrete - maybe with reinforcement in the form of plastic fibres.
2. putting a tack coat and then ashphalting over the top.

Any suggestions would be very welcome as I suspect that I risk making a costly mistake.

I would like to get into a state that it wont damage road cars (or their occupants) and that will be reasonably easy to maintain. Of course cost is a major concern.

Cheers

no ashphalt and tack coat,as this will just gloss over ther hole they will soon show through ashphalt and show every crack in concrete,
i would go for saw cutting out the patches and re concrete,if the original has no steel in it putting steel in new wont have much benifit :;):

like msh said cut the bad section out, shutter and form a expansion/contraction joint for the new concrete with rebar drilled into the existing concrete, or you risk the new slab rocking or sinking/cracking when trucks run over. for trucks and tractors recommend minimum 200mm better 250mm.

next option rib it up, crush it, lay a road made out of the crushed concrete or then re concrete but you're looking at over 60m3 of c30/35 concrete to relay so roughly £6000 in just concrete.

the spec we use for commercial farm yards is as follows



this might be over engineered for your use but it'll give you 30 more years use.
