Road Resurfacing - Micro Asphalt
Discussion
Hi All,
We've had an ongoing farce on our road with the local council doing a terrible job of surface dressing the road to the extent that it failed almost immediately resulting in debris and stones everywhere.
The surface is currently far worse than when the undertook the original dressing. Repeated remedial patching has done no favours and caused huge disruption to residents.
That being the backstory the Council has at least accepted their attempts are far from acceptable and have just written to all on the road so say;
"In order to prevent future problems relating to loose aggregate we propose to lay a Micro Asphalt surface which will also regulate the surface profile, resulting in a smoother running surface"
Now given the incompetence to date I wonder if anyone can comment on whether this is a solution we residents should welcome or be resistant towards? It seems the Council have been led on a merry dance by contractors so far and wonder if this is more of the same or a viable solution?
Many thanks

t?Surface dressing is basically a layer of bitumen emulsion and then uncoated aggregate chippings, usually 10mm nominal size spread over the surface and rolled in. It can fail for all sorts of reasons, if the chippings are dirty they won't stick, if it's too cold they won't stick and if there are too many, the excess won't stick. Additionally tightly turning vehicles, particularly in urban areas tend to strip the chippings off the surface.
Micro asphalt is a bitumen emulsion which contains fine aggregate, typically smaller than 4mm nominal size. Unless it goes disastrously wrong at installation, it works well as all the aggregate is coated and sticks together as well as to the underlying surface. It also seals the surface of the road preventing water from getting in and causing further damage. I'm not sure that it will regulate the road surface as it's only 3-4mm thick but overall it's a better solution than surface dressing, particularly in urban areas.
