IMS Infrastructure Management Services Arden Hills Report P a g e | 14 <br />Marginal (PCI = 40 to 50) – Progressively Thicker Overlays <br /> <br />Chatham Court from Chatham Avenue to North END (GISID 1303, PCI = 47) – Marginal streets have <br />distresses that tend to be localized and moderate in nature – that is they do not extend the full length of the <br />segment and can be readily dug out and repaired. This street segment highlights this characteristic as the <br />failed area does not quite extend the full length or width of the roadway and is still serviceable. Rutting and <br />patching, as well as longitudinal and transverse cracking are the primary cause of deterioration on this <br />segment. <br />Marginal streets that display high amounts of load associated distresses are selected as a priority for <br />rehabilitation as they provide the greatest cost/benefit to the City. If left untreated, Marginal streets with <br />high amounts of LADD would deteriorate to become partial reconstruction candidates. Marginal streets that <br />are failing due to materials issues or non-load associated failures may become suitable candidates for thick <br />overlays if deferred, without a significant cost increase. <br /> <br />
