  2. Safe Roads, Reliable Journeys, Informed Travellers The following areas will be covered in this presentation: • Research during 2004/2005 • New procedures for Research proposals • Value Management Workshops • Research proposal for 2005/2006 and beyond

  3. Research Projects 2004/05 • Separation of cyclist and Pedestrians from motor traffic- Report awaited • User tolerances to vibrations on footbridges- Work completed –Report awaited • Scoping study Timber Bridges –Work completed- Report awaited • Waterproofing of decks- Stiffness of membrane/ thin surfacing –Completion 03/06 • Waterproofing of decks – Early application – Completion 03/06 • ATM gantries – High -sided vehicle buffeting effects – Completion 09/05 • Durability of hinge-decks – Draft of BA to be circulated shortly

  4. Research Projects 2004/05 • Fire protection of tunnel assets- Second draft being considered • Implications of EU Directive on tunnels- Report is finalised • Fire detection and suppression in road tunnels- Draft final report received • Innovations in Road Tunnels- Report finalised – Review recommendations. • Performance Indicators for highway structures – Trial Documents available • Trial use of recycled aggregates in structural concrete- Seminar held- Draft BA in progress

  5. Research Projects 2004/05 • Crevice corrosion investigation in post-tensioned structures- Research findings being considered by HA • Footbridge dynamic response properties – Final report in Autumn ’05 • WIM systems and braking forces for abnormal loads- Work completed • The effectiveness of sub-standard shear reinforcement in bridge decks – Phase 1 • Tests on RC beams strengthened for shear using FRP laminates – Third Report • Behaviour of RC beams strengthened for flexure - FRP laminates – 4th Report • Performance assessment of FRP bridge decks: Testing of deck sections under static and dynamic loading – Phase 3 Report

  6. Research Projects 2004/05 • Near surface mounted FRP for bridge strengthening • Fire detection and suppression in road tunnels • Acoustic emission for hinge decks • Fire protection of tunnel assets • Effective post- incident recovery in highway tunnels • Primary safety for tunnel users • Design guidance for non-ferrous rebar

  7. Research Projects 2004/05 • Tunnel emergencies:emergency evacuation • Expansion joints for integral bridges • Use of mechanical ventilation in tunnel emergencies • Effectiveness of washing bridges

  8. Research Value Management Workshops

  9. Value Management Workshops: Development of the R&D Programme: • New proposals received (Oct 04) • Bids collated and evaluated • Proposed projects prioritised • Programme matched to available resources • Draft programme to HA Board (Jan 05) • Submission to the Minister (Feb 04) • Approval by the Minister (April 05)

  10. Value Management Workshops: HA Research Themes: • Accessibility • Asset Use • Driver information • Improved safety • Integration • Reducing congestion • Sustainability

  11. Value Management Workshops: The Essential Criteria: • Benefits must be clearly identified • Proposals must be feasible/achievable • Proposals in line with HA objectives

  12. Value Management Workshops: Criteria used for 2005/06: • Improving safety • Reducing congestion • Reducing environmental impact • Enhancing driver information • Optimising WLC • More effective technical governance • Speeding up delivery • Developing Traffic Operator role • Wider benefits

  13. Value Management Workshops: Scoring: • Benefits Score of 0 – None benefits Score of 10 – Exceptional benefits • Likelihood – Score (0 - 10)

  14. Research Value Management Workshops Proposed Research Projects for 2005/06

  15. Proposed New Projects 2005/06 • Early application of waterproofing systems to bridge decks • Impact of revised HSE Standards on tunnels • Assessment rule s for web stiffeners in steel bridges • Half- joint bridge testing • Temperature effects on integral bridges • Design and strengthening of bridges for vehicle impact (desk study) • Assessing defect acceptance in FRP materials • Steel fibre-reinforced concrete – Concrete Society Report
