The 2018 program will be the 6th year of the 10 year renewal millage approved in August 2012. The Department of Public Works evaluates the condition of the City’s roads and prepares a proposal to be approved by the Livonia City Council. Interested citizens are invited to communicate their concerns at the Citizen’s Advisory Committee on Roads annual public hearing held prior to approval. Consultants then prepare, plan and administer the program according to specifications.
Road repairs are divided into three (3) categories: RECONSTRUCTION, REHABILITATION or MAINTENANCE. Based on the Pavement Surface Evaluation and Rating (PASER) determines the treatment techniques. PASER Rating is based on a number system, 1 through 10 with 1 being the worst and 10 being the best. Other factors along with the PASER Rating to determine the locations for repair include the following: proposed water main or sanitary sewer maintenance or replacements, tree removal and replacements and other road proposed improvements by the Michigan Department of Transportation or Wayne County in the vicinity.
Total reconstruction of a road segment consists of removal and replacement for both concrete and asphalt requires a PASER Rating 1 to 3. Underdrains will be provided to reduce water from below the ground and prolong the pavement life. Sidewalk ramps will be provided meeting ADA compliance.
For both concrete and asphalt roads, Rehabilitation consists of the removal and replacement of failed sections of concrete or asphalt road and the placement of a 2.5-inch asphalt cap or pulverizing existing asphalt pavement and placing a 3-inch asphalt cap. Based on the cross section for asphalt roads consisting of concrete curb and gutter, sections of deteriorated concrete curb will be identified and removed, especially near drainage structures in order to provide positive drainage. New drainage structure inlets / covers will be provided in the areas of replacement.
For concrete roads, Maintenance techniques consist of the removal and replacement of selective sections of concrete road segment typically consisting of less than 30% of the total road segment. In some areas, underdrain will be placed and trees removed to accommodate this treatment. For asphalt roads, Maintenance techniques consist of the placement of a 1.5-inch asphalt cap over a road segment with minimal if any removal, including crack repairs.
