| Over
the course of five
decades,
Postiano Paving had developed a process that is second to none.
It's a process that has been refined and improved into a flawless
procedure that virtually guarantees success. Should you decide to acquire our services, which are based on
over 50 years of
experience in the paving trade, the following is a brief outline of what you will
actually be purchasing. |
| So once you contract a
Positano Paving crew, what actually happens?
Preparation
 irst,
their work crew arrives at the job site with modern,
specialized asphalt paving equipment. They begin
their work by measuring the work area
and setting up string lines. At that point, all visible weeds in the work area
are removed either by hand (in hard to reach areas) or with the use of a back hoe. The string
line is to help ensure that the crew marks the boundaries of the work area as accurately as
possible. |

|
In the event that the job requires excavating, this is done properly and
efficiently with a back hoe.
and / or a skid steer
/ bobcat machine for excavating purposes.
After the initial preparation of excavating
and removing weeds
is completed, Positano Paving then proceed to grade the area to be paved. This process
is critical as the overall quality of the paved surface is directly related to the
quality of its base.
Since the purpose of the paving machine is to lay asphalt
in a uniformly even and smooth manner,
this machine is also used in preparing the grade of work
area. This helps remove low and high spots on the area to be paved. As
the work area is graded,
the professional, trained crew is constantly measuring, via a straight edge and a level (or
transit, if necessary) the fall of the entire area to ensure that water drainage will be
proper and flowing to the desired locations.
After the initial grading,
workers compact
the area with a 3-ton compactor that has vibratory capabilities of up to 10-tons.
Then the entire area is fine-graded
and the drainage of water is re-checked. Meanwhile, the
graded edges are being compacted from the sides by a hand held
'tamper' at a
45-degree angle. Why? To strengthen and support what lies between those
edges. After the manual compaction, a plate compactor is taken around the perimeter
of the work area and anywhere a self-propelled compactor isn't suitable.

Laying the
asphalt
 hen
the asphalt arrives, it is dumped into the paving machine
laying the asphalt and laid at a depth that will later be
compacted to a minimum of 2". Boards
are placed along any edges that are required to be straight and the asphalt is placed up
against the boards in order to achieve this. |
|
|
A special asphalt glue may be used at
any joints where the new asphalt may be meeting old asphalt in order to prevent the two
from separating in the future (as a result of snow-plows, frost etc.).
Positano Paving uses a
Ministry of Transportation-approved mixture of asphalt called HL3. It is the same mixture that is used for the top layer
of most highways, so a durable and long lasting driveway is installed. When
the asphalt has cooled to the proper temperature, the crew begins the process of compacting it. Proper
compaction is the key to a long-lasting, low maintenance driveway.
First, we
compact the entire area with a 1-ton compactor. When the asphalt has further cooled,
we then compact it with a 2-ton compactor. Again, the edges are compacted manually
at a 45-degree angle, as well as with a plate vibrator. The process of
compaction is the most time consuming and important aspect of our entire asphalt pavement
installation procedure. For this reason, we have in total 3 different sizes of
compactors and 2 plate vibrators to ensure our compaction is done properly.

Completion
inally, we clean the edges of the paved area and any mess we
may have made while working, and erect a barrier to keep traffic off the newly installed
pavement. |
