SPRING CLEANING: Help your driveway recover from winter wear and tear
on 18 May 2018
Engineering experts at Mark Cadam Ltd have the following advice for horse owners considering surfacing or renewing the existing surface of laneways after a long winter

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

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:

  • Renewal of existing lanes and roadways
  • Surfaces where potholes are beginning to form
  • Sealing existing Clause 804 lanes or roadways
  • The main function of surface dressing is to:

  • To provide a non-skid wearing surface
  • To seal the road pavement against the ingress of water
  • To arrest disintegration and hence extend the life of the pavement
  • To provide a more uniform appearance for a patched road
  • 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

    Road recycling and surface dressing is recommended for roadways that have that have failed due to:

  • Excessive rutting
  • Excessive cracking
  • Excessive potholing
  • Multiple surface failure
  • 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:

  • Reduction in raw materials – savings in the amount of aggregate imported by utilising the existing pavement materials.
  • Reduced accommodation works – Fewer requirements to raise entrances, kerbs and road verges compared to traditional overlays.
  • Reduced vehicle movements - reduction in the numbers of construction traffic on the surrounding roads.
  • NEW ROADS

    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.
