Thread: Has anyone used Recycled Asphalt.

I’d be checking with a local landscaper but I have heard that recycled ashpalt even when well compacted has a high propensity for hot pick-up
Which in your situation may make a mess of your very hard worked pavers?

Crusher dust with a bag of cement per 4-5 m2 raked through prior to compacting and then watered down can make a pretty good low dust drive if not too much traffic or speed on it?
If you can get 8m2 crusher for $286 and spread it 10cm thick (80m2) then run 20 x $7 bags of cement your looking at the same price as asphalt with only a little bit more labour ?

I used the above for a short section of drive in Cooktown which use to be a creek so in the wet most aggregates washed away ... concrete would have cost too much ($400+ a cube up there)
Anyways it lasted more than 5 years with no real upkeep needed and was largely dust free?

Oops just saw $286 was for crushed Crete
Wild have to work out the price delta on crusher dust but it’s an option to put in the mix

I know how you feel Shane, I hate mud!

The pavers look like a nice job, although I can't tell from the pic's if you have haunched them in, i.e. put a sort of shoulder of cement around the edges, which it pro'ly needs for vehicle traffic. YouTube

My mate put down Rec-Asphalt for his driveway about 10 yrs ago, and it has been fine, although it is more of a 3-way turning area, and under tree cover so I can't speak as to hot pick up and dust.

I know putting some cement in with crusher dust can firm it up nicely, as the guy who did my approx. 1m high retaining wall did that as a footing for it and it hasn't moved.

You're right about metal in rec-concrete, I've seen bits of reo in it!

Consider CRB, properly rolled it lasts well.

Recycled asphalt (or RAP) is the waste end product from asphalt road resurfacing. It is the profilings or chunks of asphalt that come out of the asphalt profiler or grinder.
Asphalt is the same as concrete except it uses bitumen as a binder instead of cement but the base product is the same- quarry stone.
The size of the particles depends if the profiler was a course drum (particles are about 25mm dia) or fine drum (about 10mm dia)
Recycled asphalt is better than recycled concrete in your application IMO. It doesnt produce dust the way recycled concrete does and doesnt wash away either.
It can be compacted down to form a hard surface but will never look like asphalt. It will always be a gravel.
I spread RAP on my gravel driveway about 10yrs ago and it is still stable and not muddy during rain.
You will need to check with your local council if they will allow you to place it though. Some "green" councils dont like the bitumen.

Hope this helps.

Thanks Guys,

I may just give it a go. worse case is we'll end up with gravel over the top if it doesn't work out. As for the council, not in a million years when I tell that bunch of hypocrites anything

Oh yeah, the pavers do have edge restraint. Concrete about 2/3rds of the way up the side of the 80mm paver. They are commercial grade heavy zigzag pavers. The paving job is far from perfect (a million miles from it infact). But it is sound and adequate .... and we can walk inside now without walking mud everywhere I've found the kids like the large level('ish) area to play netball on too.

Just be careful Shane, they will make you dig it up as a minimum check out their green policy, it's usually on their website.

Yep, I'll get right on that .... You have obviously never tried to deal with our council. The only thing they are capable of is trying hide the next "funded fact finding trip" overseas. Same deal with the trees that have, er, "fallen down" that were to close to our house. Not in a million years would I care what the council thinks.

To put it into perspective, I live in Ballarat. if I dig down 3mm ... we break through the "top soil" and find the broken up granite and clay. ie: the entire area is leveled out mullock heaps. The only thing that grows in the area is weeds, radiata pine and blackberry/gorse. Don't get me wrong, its a lovely area, but we are not talking protected native bushland here. We are talking a 100+ year old mining site

I ripped a drain down our fence line last year... We now have a pile of jagged bits of granite perfectly washed and shiny at the end of it. We must have had one of those horse drawn rock crushers located at the corner of our block.

eg:





They are broken down to pea sized rocks. but still sharp and jagged like freshly smashed rock.
