Construction Asphalt
paving is the cornerstone to any asphalt
paving / maintenance company. M&D Blacktop
provides its customers with the experience
and quality that is essential to any paving
project.
Asphalt Overlay:
 As asphalt ages and extends past its
designed life cycle, it will become
necessary to install a new layer of asphalt
that will extend the wear life of your
asphalt surface; this process is called
asphalt overlay.
In dealing with an asphalt overlay it is
essential that your contractor be aware of
several items:
|
|
How will your pavement drain
water after the overlay is
completed? |
|
|
What types of repairs are
necessary to be completed prior
to installing the new asphalt
surface? |
|
|
What type of butt joints will
be needed? |
|
|
How much scratch course will
be necessary to help alleviate
the potential of low spots? |
|
|
What thickness (compacted) is
recommended for the existing
traffic patterns and load
trucks? |
All of these issues should be discussed with
your paving contractor prior to signing a
contract.

Example Specification for an Asphalt
Overlay: |

Asphalt Overlay
Clean and remove all loose debris from
proposed surface.
Drainage and Transition:
1. To allow for a smooth transition after
the overlay and allow for proper drainage,
we propose to grind butt joints where the
new asphalt will meet transitions points,
i.e. existing asphalt, handicap ramps,
loading docks, dumpster pads, entrances and
exits, etc...
2. Install riser rings to all catch basins
or grind around them.
Repairs Prior to the Overlay:
1. Remove potholed and/or deteriorated
asphalt and base from designated area(s).
2. Install compacted #304 base stone if
necessary.
3. Install 3 of compacted #402 base course
asphalt.
4. Repair area(s) = X sq. yards.
Overlay: 1. Remove
car blocks (if any) and store them on site.
2. Apply asphalt tack coat to entire surface
at a rate of 0.06-0.10 gal/sq. yard.
3. ** IMPORTANT ** - To help pre-level the
existing asphalt, we will install a
leveling-scratch course to low areas as
necessary. This can not guarantee the
elimination of low spots but will greatly
reduce them.
4. Pave 1 ½ of compacted #404 finish course
asphalt.
5. Re-set car blocks. |
Some existing asphalt surfaces can not
simply be overlaid. If pavements are old and
already have several layers of asphalt
installed or are severely pot-holed and
functionally unsound, they might need to be
milled prior to re-paving. In some cases a
portion of the pavement detail may need
removed, rebuilt, and repaved.
M&D Blacktop has the experience necessary
to help you evaluate your asphalt and assist
you with your decision.

Example
Specification for an Asphalt
Milling and Re-Pave: |
|
Asphalt Milling and Overlay
Milling: 1. Mill
existing asphalt to depth of 1 ½ below
existing grade.
2. Provide trucks for hauling and crew for
supervision.
3. Clean all debris off of asphalt and prep
for overlay. Drainage
and Transition: 1.
By milling the existing surface, we will not
affect the drainage of the pavement.
2. All transition joints will be milled by
the grinding equipment.
Asphalt Repairs Prior to Overlay:
1. None. Overlay:
1. Remove all car blocks and store them on
site (as needed).
2. Apply asphalt tack coat to entire surface
at a rate of 0.06-0.10 gal/sq. yard.
3. Install a leveling-scratch course to low
areas as necessary. This can not guarantee
the elimination of low spots but will
greatly reduce them.
4. Pave 1 ½ of compacted #404 finish course
asphalt over entire surface.
5. Re-set car blocks. |

needs may also grow. M&D Blacktop can help
you through the process of increasing your
existing asphalt parking lot, or help you
build one from scratch.
M&D Blacktop has business relationships with
engineers that can provide you with the
