Overview
The Town of Onoway has a surprisingly large industrial base for a community of just over 1,000 residents, including agricultural and oilfield services, manufacturing and fabricating, construction, and environmental management. As these industries grew, an ‘industrial district’ became established on the north side of the town along Industrial Avenue. This heavily used road quickly submitted to the stresses of increasing usage and required repeated repairs and rehabilitation over several years. Like many aging, unpaved rural roads in Alberta, Industrial Avenue was built using construction methods and materials of the time, and never imagined supporting the weight and speed of today’s commercial vehicles. Industrial Avenue’s existing subgrade, consisting of organic and other non-standard materials, was rotting away beneath the strain. The Town’s Public Works department learned of Paradox Access Solutions’ successful road rehabilitative work and sought a design that would strengthen this important artery to meet the growing traffic demands and alleviate future repair and maintenance costs.

Industrial Avenue’s existing subgrade, consisting of organic and other non-standard materials, was rotting away beneath the strain. The Town’s Public Works department learned of Paradox Access Solutions’ successful road rehabilitative work and sought a design that would strengthen this important artery to meet the growing traffic demands and alleviate future repair and maintenance costs.
Challenges
An aging unpaved roadway was failing under the stress of growing industrial traffic. The existing subgrade was in a state of decay and the road surface had reached a point where repairs were frequent and proved ineffective for long-term reparations. A public works official for the Town approached Paradox to determine what could be done to improve the road within the Town’s available resources.
A single layer of 150 mm high Type D ToughCell® Geocells was installed over the graded road surface. A separation layer of geotextile was placed between the prepared subgrade and the geocell layer. The cells were infilled with 40mm crushed gravel to 175mm depth and compacted to 98%.
Total area: 250m x 8m
Product(s): 330-150 Type D ToughCell® Geocell; woven geotextile
Infill: 175mm crushed gravel
Completion: The road surface was capped with a 75mm asphalt layer.
Benefits
The rehabilitated Industrial Avenue continues to perform well for the Town of Onoway after five years of service and remains in immaculate condition. The Town now enjoys a low-maintenance, comfortable asphalt roadway in place of a damaged and non-serviceable unpaved road that strained the town’s resources with multiple and repeated repairs.
The Town has benefited from an affordable construction solution that has greatly reduced ongoing maintenance costs. Residents and customers now have reliable, safe access to Industrial Avenue businesses which will encourage continued economic growth of the Town.
Results
Industrial Avenue continues to perform well for the Town of Onoway after
five years of service and remains in immaculate condition today. The Town
now enjoys a low-maintenance, smooth-riding asphalt roadway in place of a
problematic gravel road that strained the town’s resources in ongoing repairs
and maintenance.
