Reconstruction and Asphalt Paving Program
2008
Program Update Information
Leduc
County has
commenced its second year of the five-year Road Reconstruction Program
within Nisku. The 2008 program will consist of the following phases of
work:
-
installing
sub-drainage along
5th street
and 15th Avenue;
-
re-construction of
5th Street as far as Highway 625; and
-
completing drainage
and ditch work along 8th Street.

Thank you for your
patience and support for the road program in Nisku. If you need further
information please call 955-3555 Ext 3289.
What is being done to
5th
Street and why?
Drainage Improvements –
Water is one of the biggest factors in weakening a road. In order to
keep water out of the road structure, the ditches will be re-graded to
reduce the amount of standing water. All the culverts along the road
will also be reset or replaced dependant upon their condition. As well,
a sub drain will be installed in each shoulder of the road to help
improve the drainage of the road structure.
Roadway Widening – The
width of 8th Street varies along its length and is
sub-standard for the size of vehicles using it. In order to improve
this, the roadway will be widened to approximately 11 metres. The
widening will be completed within the existing road right-of-way, and no
additional land will be required from the properties along the
construction zone. As well, the turning radiuses at the intersections
will be improved allowing for safer turning movements.
Roadway Reconstruction and Strengthening
– Many of the roads in Nisku were
never designed to handle the size or volume of vehicles and equipment
that are currently using the Nisku Industrial Park. In order to meet the
modern needs of the businesses operating in Nisku, the roadways must be
strengthened. To provide the required strength, a number of improvements
will be done:
-
Incorporating
powdered cement into the subgrade to strengthen the existing clay
and clay tills at the bottom of the road structure.
-
Addition of a
new granular base layer.
-
Cold-in-place
recycling of the asphalt and gravel in the old road structure to
form a new asphalt base layer.
Placing 100mm (4
inches) of new hot mix asphalt pavement on the surface.
Traditionally, road structures are designed
for 100% loading of legal weights. The design for 8th Street
will upgrade the road structure to be able to withstand 25% over
weights. As part of the program, all access
approaches will be reconstructed and paved to the property line.
How will this work affect
my Business Operations?
During the road construction work, the road
itself will be closed to all through traffic. Local access will be
maintained and all businesses will have access to their properties
throughout the construction. There will be periods of time in which
access to individual businesses will be impacted (i.e. culvert
replacement or access approach reconstruction). These disruptions will
be minimized as much as possible and will be pre-scheduled with the
affected businesses. The disruption of any access will only occur with
the agreement of the business and will only be done at the times agreed
upon and for the specified time periods.
How much will this cost
and how is it being paid for?
Leduc County Council has signed a five year
contract with West-Can Seal Coating Inc out of Didsbury Alberta for a
minimum of $15.0 million. That represents an investment of at least $3.0
million each year for the next five years. The advantage of signing a
five year contract is that the County has more control over the
escalating construction costs that we are currently seeing. As well,
the work will be performed using in-place recycling techniques. This
process will reuse the existing asphalt and gravel in the road structure
and reduce the amount of new materials that will be required and thus
further reduce the construction costs. Not only is it cost effective, it
also good for the environment. Cold in-place recycling can produce one
tonne of recycled asphalt using approximately 1 litre of fuel.
This program will be funded through the Alberta
Municipal Infrastructure (AMIP) and New Deals for Cities and
Communities (NDCC) Grant Programs.
How do you know this new
in-place recycling technology will work?
Although the technology is new to Alberta, it has
been in use in eastern Canada and the United States for close to 20
years. West-Can Seal Coating Inc.’s parent company, Seeley & Arnill
Construction from Durham Ontario, has been a pioneer in the cold
in-place recycling industry since 1989. During this time period they
have completed just over fifteen million square metres of cold in-place
recycling and based upon the their experience and the engineering
analysis, we expect this technology will produce roadways that will meet
the needs of the Nisku Industrial Park for the next 15-20 years. With
the increasing costs in raw materials (oil, fuel, aggregate, etc) and
the concerns with greenhouse gas emissions, cold in-place
recycling is destined to become a mainstay in road reconstruction and
rehabilitation.
