Red Deer County Subdivision Paving Program

Red Deer County

Project Description

Red Deer County had 6 sites in need of pavement rehabilitation. Balmoral Heights, Forest Green, Fort Normandeau Road, Twp Rd 384/RR12, Valley Meadows, and West Ridge Estates. These sites ranged from two lane rural roads to country residential subdivisions. The sites were all chosen to receive repair in order to maintain their level of service and extend their overall life. Tagish and Union Street were the engineering team that provided the design, contract management, field, and testing services to successfully complete this project.  

The end use of these roads varied significantly, as such the traffic volumes, amount of heavy hauling, existing structure, and road width were important elements for consideration during the design process. To gather background data, Union Street completed asphalt coring to help verify existing structure depth. This helped the design team determine whether the grade line could be adjusted up or down. Additionally, there were localized areas within each of the sites that required repair before asphalt re-surfacing could be completed. This project was a multi site, annual pavement rehabilitation program requiring a team of dedicated individuals.   


In some of the Country residential subdivisions the design decision was made to mill a portion of the existing asphalt to tie into existing driveways and maintain valuable road width. When completing the milling, the weight of the construction equipment caused further road failures. This high risk of additional failures was considered before starting other sites. Further consideration was given to milling depth and order of construction operations. Construction equipment itself is often the heaviest loading these lightly structured roadways will experience so this should be considered when preparing constructable designs.
