WHEN it comes to surfacing or renewing the existing surface of laneways, the choice of options is dependent on the existing surface condition, or whether a new roadway is required.
Surface dressing is the application of a layer of bitumen emulsion and a single sized aggregate chipping in one or more layers and is recommended for the following:
The main function of surface dressing is to:
We use specialist equipment known as “combination units” for this process that allows for the application of bitumen emulsion and chippings simultaneously to varying widths. This results in a single pass process that is more economical, safer and durable with the elimination of joints.
Road recycling and surface dressing is recommended for roadways that have that have failed due to:
Road recycling is the term used for recovering and re-using material from the existing pavement and has become an increasing popular choice of road maintenance and rehabilitation for the local and regional road network throughout Ireland.
This process pulverises or mills the existing surface material to the required depth and produces a material with the same grading specification as Clause 804. The recycling machine has the capacity to stabilise the material with the addition of a bitumen emulsion resulting in a structurally rehabilitated layer that is flexible and fatigue resistant.
Once the road is milled the in-situ material is regraded to the required levels and compacted by vibrating rollers. This material is then sealed by the application of surface dressing to provide the user with a finished road surface.
Benefits of the road recycling process include:
For the construction of new roadways, we recommend the laying of Clause 804 or Clause 806 with a road paver to ensure the optimum rideability.
Once the material is laid and compacted to the required level this is the sealed with a double surface dressing of bitumen emulsion and chipping to provide the finished surface.
Mark Cadam Ltd can provide all of the options for surfacing or renewal of existing laneways, mentioned above.
