Your pump is having trouble keeping up when your tapping , especially strating off with lower amount of nozzles ,low bar pressure, lighter application rate , if membrane for asphalt then not so crucial
A couple of reasons. The stones have at least two fractured faces. This stone is granite and does not come from a river bed, so there are no rounded edges. The stones are there first and foremost to protect the bitumen. The second reason is to provide another wearing surface and the third reason is for added traction. About half of each individual stone is left exposed, the other half is buried in the bitumen. The roadway is quite a bit less "slippery" than the original asphalt even during evens of ice, snow, and rain. There are some places where they will use a rounded river rock because they do not have access to larger stone to crush or they just do not have access to a crusher. A rounder, smoother rock would of course provide less traction during evens of ice, snow, and rain. Like I said though, the stones are there predominately to protect the bitumen. What is the average life of the bitumen that you apply to a heavily traveled roadway?
@@AsphaltMaintenanceGroup Can you come to my town and instruct our idiots on how to repair a road? They seem to "fill hole, go for drinks" and that's it.
The meet line is a fine area that can be sprayed again but spaying over the area that's already oiled and graveled is wrong and that will be a high ridge in the road!
I agree with JC Traveler what he said but The driver operating the controls in the cab of that tanker is excellent In England what we call cutting in we have a man on the back to do this Excellent equipment as well 👍🏻
It isn't about packing in the rock. The rollers are there to tip over any rocks into the emulsion. The finished layer is only 3/8" thick, the thickness of the aggregate.
Carmine there is a lot that goes into the answer. A chipseal is only as thick as the aggregate used. You are talking about an inch and a half overlay? What are you trying to "fill". A slope or crown can easily be made with a paver. What is the application you are looking for?
Apologies but, you caught me waking up this morning. The emulsion used was a CRS2P. Cationic Rapid Set 2 part polymer. Why are you wanting to slow down the break time of the emulsion?
