ASPHALT OVERLAYS
The following is some basic information that may be useful
if you are interested in an overlay or be a candidate for an
overlay.
- What is it . . .
- A pavement overlay is the application of a layer of
hot bituminous paving to an existing paved residential driveway,
commercial parking lot, or road that has deteriorated from years of
wear from traffic and the environment.
- Why is it done . . .
- An overlay adds structural capacity, riding comfort
and skid resistance, which adds to the good look and safety. Smooth
road surfaces also decrease vehicle maintenance costs and improve fuel
economy. Pavement overlays help reduce traffic noise, which is
important in urban developments. New overlays are aesthetically
pleasing, as well as structurally sound and cost efficient.
- Pavement deterioration is cumulative. Pavements
generally deteriorate at an ever increasing rate. Factors
including, weather, traffic impacts, frequency of maintenance,
etc. all contribute to a asphalt's longevity.
- Routine maintenance is essential ! When a paved
road, parking lot, or residential driveway reaches about 75% of
its service life (10 to 20 years, depending on base stone and
asphalt thickness), deterioration accelerates. If routine
maintenance is not performed restoration costs are four to five
times higher. An overlay can give you a new surface for a fraction
of the cost of starting over.
- What can be expected . . .
- During your residential driveway project, you may be
asked to remove your vehicles from your garage, or not drive on it,
for the next 2 following days. While traffic on roadways is commonly
allowed access soon after paving, it is your driveway. Access to the
motoring public is the key reason for opening roadways sooner.
- On commercial-type overlay projects, access
issues should be agreed upon before the start of your project. We
can work with any access related concerns, from limited to full
access. Please discuss this with your project manager.
- During a road overlay project, residents must
remove all vehicles from the street. If curb and gutter is present
the old pavement will be milled along each edge so that when the
overlay is applied the surface of the new pavement is level with
the gutter. The street is then sprayed with a thin layer of
asphalt called a tack coat so that the new pavement will stick to
the old pavement. The overlay is then applied. Traffic should be
kept off the new pavement for at least four hours after it is
laid.
- If your project has a stable base stone course,
the asphalt is basically structurally sound, and water drainage
(pitch) poses no particular problems, it should be a candidate for
overlay. Contact Us with more questions about your particular
project.
