Presentation Transcript

  1. NJUG Position - Overview • welcome invitation onto CSS Project Team • NJUG’s views have been tabled through the Project • respect development of an Algebraic Charging Model • simplified Modelling is an obvious approach to take • treated as a credible research exercise • Project Output could be used as a starting point if: • NRSWA §78 brought forward by Government • TMA Half/Full-Width Resurfacing measures considered by Government CSS - Long Term Performance of Reinstatements - Phase 2

  2. NJUG Position - Concerns [1] Is the Damage Case proven for ALL reinstatements? • Long Term Performance of Reinstatements - Phase 1: • TRL Final Report - up to 30% of surface defects may lead to deterioration • DfT Response to Transport Committee’s Report on Local Roads and Pathways - not convinced at this stage to activate §78 • So, should a 0.3 multiplier be applied to the conclusions? • Only 20 or so US/Canadian Cities - selective? • no Damages in New York City • no Damages in New York State (~57 Counties) CSS - Long Term Performance of Reinstatements - Phase 2

  3. NJUG Position - Concerns [2] The algebraic components - should they always apply? • Condition of Roads: • is it appropriate to average UKPMS data for ALL Highway Authorities? • very Limited UKPMS data on Road Categories 3 and 4 • these will vary in every Highway Authority CSS - Long Term Performance of Reinstatements - Phase 2

  4. NJUG Position - Concerns [3] • Extent of Reinstatement in each Road Category: • Is Halcrow data representative of the next year’s cross-Utility activity • Is it safe to extrapolate linearly over 40 years • Reduction in Carriageway/Footway Life: • 1 year, 2 years, 6 months - how can this be verified by Utilities? CSS - Long Term Performance of Reinstatements - Phase 2
