We have a number of very steep streets with up to 30% grade. Whilst it is unlikely that we would build streets with that grade any more, many still exist with bitumen or asphalt surfaces. These are nearing the stage of needing new surfaces or asphalt. However, our resurfacing crews are not prepared to undertake the work due to safety concerns - the grades are steeper than the manufacturers recommended gradeability of their machines.
Has anyone had experience with resurfacing roads on steep grades?
G'day
Thank you for your comments. Our big challenge is the rolling and the danger of the rollers sliding down the hill.
I've attached a few images that show some examples, although I'm not sure that some of the images really do it justice!
Hi, I discussed your problem with a very experienced asphalt contractor who suggested that you may need to invest in a PTR (pneumatic tyred roller) to avoid the possibility of the roller slipping on the newly laid asphalt.
Hope that helps, Robert.
Thanks
We normally use a multityre as the second part of the process and may need to leave out the steel roller.
Starting to explore a skid-steer attachment. We use bobcats for excavation, loading, cold planing, levelling so why not for rolling?
Could become an option for small patching jobs?
