The slurry seal microsurfacing incorporates bitumen emulsion and fine graded aggregates with fillers. It re-profiles existing surfaces to restore texture and seal the surface. This will extend the life of the footways and is an example of how MK Highways applies it Asset Management principles to reduce 'whole life costs'.
The micro and slurry surfacing processes is a manual operation, it consequently does not use excessively large or noisy machinery. All the requirements for a project can be loaded onto a single large heavy goods vehicle or 3.5t pickup and transported to the work site. Smaller pedestrian mixers can be used both alongside very busy roadways and inaccessible sites, with minimal disruption to road users, pedestrians and local residents.
