Crushed Rock Driveway

Hi All,

I am about to resurface part of our driveway with 20mm crushed granite which was last done with the same stuff about 5 years ago. I've found it to be really good but part of the driveway that slopes down tends to form rutts if we have ridiculously heavy rain which we have probably once a year.

I was wondering whether buying the crushed rock with cement mixed in would stop that. One of the garden supply places said it wasn't worth paying the extra and said to get some bags of cement and rake through before wacking the driveway. Another garden supply place said that buying it pre-mixed or raking it through with cement won't help with the heavy rains anyway and that I'm better off just buying more crushed rock and filling in the rutts when it happens.

Just wondering if anyone has any thoughts on using either plain crushed rock, or cement stabilised crushed rock.

You can mix cement through it, but yes they were right and it isnt as consistantly hardened all over the area, it has to be mixed thoroughly to get evenly through the whole rock.

Stabilised will be much better, or a wet mix (which has a lower cement %), low to mid $40/m² from Boral if you need a fair load. It wacks down as hard as rock if you spread it and compact pretty soon, dont let it get too dry.

Thanks for that. The wet mix sounds like the go. I hadn't heard of that before.
