Asset Management Plan - Newcastle City Council

Carriageways Life Cycle Plan14.3 ConditionThe condition of the asset is assessed by regular inspection and by using anumber of assessment techniques. Newcastle City Council has a conditioninspection regime, with information recorded in the Symology database. Thehighway inspectors give a condition rating for each carriageway during thecourse of their planned inspections using a, 1 to 5 criteria:• 1 Excellent New or no defects, negligible wear• 2 Good Small number of minor defects, few or no safetyrepairs required• 3 Fair A number of minor defects, possible patchingrepairs required• 4 Poor A greater number of minor defects, inspect forpossible scheme• 5 Bad Higher number of defects, inspect forpossible maintenance schemeTable 14.3.1 identifies the percentage ranges for particular defects (for bothflexible and rigid carriageways), which are used to help judge the conditionrating.Table 14.3.1 Condition Monitors Used to Establish Condition Rating.Rating SubSetCondition Monitor (Defect)PercentageRangeFlexibleCarriageway(1) (a) Good(2) (a) Poor Camber / Riding Quality(b) Minor Carriageway (Fretting) 5 – 50(c) All other defects Under 5(3) (a) Minor Carriageway (Fretting) 50 – 100(b) Wearing Course Deterioration 5 – 25(c) Non-structural rutting 5 – 50(4) (a) Wearing course deterioration 25 – 100(b) Non-structural rutting 50 – 100(c) Major Carriageway 5 – 50(5) (a) Carriageway 50 - 100Rigid Carriageway(1) (a) Good(2) (a) All Defects Below 5(3) (a) Wearing Course Deterioration 5 – 50(b) Surface Spalling 5 – 50(c) Loss of joint sealant 5 – 50(d) Joint Spalling 5 – 50(4) (a) Wearing Course Deterioration 50 – 100(b) Surface Spalling 50 – 100(c) Joint spalling 50 – 100(d) Area Cracking 5 – 25(e) Longitudinal and/or transverse cracking with 25mm 5 – 25difference between sides(f) Bays / Joints move under traffic 0 – 2596
