will follow the same criteria (height differentials) used for uplifts on concrete sidewalks.
Therefore, correlating the depth measurements, to asphalt severity classifications:
-
Minor Uplifts & Low Severity: less than (but not equal to) 15 mm (0.6 inches) high.
-
Major Uplifts & Medium Severity: greater than or equal to 15 mm (0.6 inches) & less than 20 mm (3/4 inch) high.
-
Urgent Uplifts & High Severity: greater than or equal to 20 mm (3/4 inch) high.
High Severity deficiencies (as well as Urgent Uplifts) are to be spray painted to alert pedestrians and reported to the Maintenance crews for a temporary patch job once all sidewalks in that respective IMS area have been inspected.
Also, if a deficiency with a height differential greater than or equal to 1.5 inches (38 mm) is encountered during an inspection, it is to be considered “Priority” and is also spray painted to warn pedestrians of its location, but will be reported to maintenance crews for repair typically the day it is encountered. This repair is typically provided as soon as possible, from the time the uplift is noted.
8. REPAIR OPTIONS
This Guide is an internal training document for staff conducting the sidewalk inspections. This Section does not dictate what repairs are undertaken but rather provides some explanatory information about possible repair considerations for information purposes and minor repair categorization purposes only. The type of repairs undertaken and scheduling is determined by Maintenance Division management staff and is subject to site-specific conditions, funding, and resource constraints.
Generally speaking, the method of repair is dependent on a number of factors including the type and severity of the deficiency and economic considerations. As an example, it could be more cost effective to perform:
-
spot repairs on severe deficiencies on a sidewalk that is in a state of overall good condition
-
slab replacement if one or more panels are affected by deficiencies but the rest of the sidewalk is in good condition
-
total reconstruction if the sidewalk is in overall poor condition instead of a large number of small repairs.
During the sidewalk inspection process, the location of sidewalk deficiencies on a sidewalk segment is recorded. From the observations recorded on the Inspection sheets, work orders are issued for:
-
Urgent Uplifts (including Miscellaneous Items & Cracks falling in this category) on concrete sidewalks and brick paver sidewalks and
-
High Severity deficiencies (including Miscellaneous Items falling in this category) on asphalt sidewalks and asphalt on concrete sidewalks.
