  1. FEEDBACK toRPF November 2004

  2. CONTENT • Overview of Conference • Theme Co-ordinators Summaries • P Myburgh Summary of CAPSA issues • Action Plan

  3. THEME AND FOCUS AREAS • Theme – Arteries of Africa • To Promote the concept of Roads being necessary to support development • Because the whole of Africa is facing a new dawn of development and self evaluation • To contextualize our technology within the greater socio-political and developmental issues in which it is applied. • Supported by 4 Theme Areas • 1. Economic Growth and Development - PH • 2. Efficient Road Provision & Maintenance - BV • 3. Human Capital Development - EH • 4. Best Practice in Flexible Pavement Design, Construction & Maintenance - AJvW

  4. Potential for Development • Natural Resources • Minerals - % of World Resources • Tourism • Phosphate Rock 55% • Chromite 80% • Cobalt 50% • Diamonds 65% • Gold 50% • Manganese 90% • Platinum Group 90% • Coal 10% • Oil & Gas 10%

  5. How to Support Development Lack of Continuity

  6. Technology in Context Technology Titanic Syndrome • E & T • Health • Strategies and Tactics • Policies and Priorities • Empowerment • Development • Procurement Processes • And Forms of Contract

  7. FORMAT • Request for Papers – more than 100 received - 90% accepted by reviewers • Bulletins also provided scope to include newer issues or late papers some • Plenary Sessions • Workshops • Poster Session


  9. WORKSHOPS (1)

  10. WORKSHOPS (2)

  11. COMMENTS ON FORMAT • All papers reviewed – some rejected • Bulletins – not reviewed • No parallel sessions • Some authors disgruntled at not presenting • Moderators summaries generally favourably received • Parallel Workshops • Mixed Success • The best workshop was the one where the convenor had taken the time to read the papers, identify issues and pose questions to be addressed in round table discussions. • The worst workshops were those where the presentations took too much time (mini plenaries)

  12. COMMENTS ON FORMAT • Poster Session • Reasonable success where discussions were stimulated • Electronic (near paperless) • Not many complaints – Read the Sabita digest! • Not much use of photocopying facilities • Professional audio-visual contractor

  13. COMMENTS ON VENUE • Contained Venue • Not much scope for delegates to disappear • Opportunities to maximise Interaction • Good Service from Sun City except for some glitches in hotel booking system • Expensive - hence many missing on last night – missed a good show!

  14. MEASURES OF SUCCESS • Attendance

  15. MEASURES OF SUCCESS • New Roleplayers

  16. MEASURES OF SUCCESS • Discussions • Human Interaction • Quality of Presentations

  17. COMMENTS AND FEEDBACK • Generally agreed it was a good conference • The best CAPSA so far? • Some minor gripes • Cost, • Sun City Hotel booking system

  18. CONCLUSIONS • Conclusions • Need to find the right balance between the author’s need for exposure and the delegates needs for identifying and understanding the key issues • Reduce size of technical committee but increase early and focused involvement of convener/moderators • Try to have future conferences at similar venues – possibly cut out midweek break • CAPSA is still alive and well as The premier road conference in Southern Africa.


  20. Theme 1 – Economic Growth and Development through Roads • One plenary session, one workshop session • Plenary • 3 invited papers, 4 refereed papers • 1 bulletin paper • 4 presentations • Workshop • 2 presentations • 5 questions related to issues identified by theme papers Economic Growth and Development Through Roads

  21. THEME TOPICS • Regional economic development perspectives • Initiatives to ensure the sustainable road provision in SADC • The concept of SDIs for overall sub-regional economic development. • Principle of subsidiarity! • Local authority development perspectives • Recent changes in infrastructure planning environment • Linkages of infrastructure planning to road development • Status Quo wrt implementation IDPs • Impacts to development through MIG and EPWP • Maximisation of poverty alleviation and sustainable development through projects • Necessary preconditions that exist for success • Measurement of success, impact of these projects • Adequate levels of sustainability • Technological case studies including training interventions Economic Growth and Development Through Roads

  22. Workshop Operation This workshop will address policy, planning and delivery constraints on the provision of transport infrastructure and the supply of roads to match the political, economic and social needs. • 40 delegates around 6 tables • Two presentations • Answered 4 of the 5 questions • Good participation • 2 hours long Economic Growth and Development Through Roads

  23. Question 1 - Labour Intensive Projects geared to provide skills, poverty alleviation and distribution of funds in the community • What are the preconditions for success in poverty alleviation and sustainable development? • Must have political willingness • Must create / have good communication • Community must “buy-in” / take ownership • Clearly accept and understand project deliverables • Project must be technically acceptable & suited to LIC • Appropriate technology should be used • Experienced project leaders needed • Requirements should match skills base with available resources • Funding must be adequate & social benefits priced • Link to integrated development & other projects • Sustainability should be considered (maintenance) Economic Growth and Development Through Roads

  24. Question 1 - Labour Intensive Projects geared to provide skills, poverty alleviation and distribution of funds in the community • How should success be measured? Social / Economic / Political? • Proper impact assessment required - before and afteri.e. Quality of Life baseline survey • Address problems of benchmarking social improvements eg school attendance , social activities, access to health facilities • Projects contribution to sustainability, other business development & economic growth to be measured • Tools to provide the above not readily available Economic Growth and Development Through Roads

  25. Question 1 - Labour Intensive Projects geared to provide skills, poverty alleviation and distribution of funds in the community • Can the current projects be used as business models? • Not adequate, caution until better calibrated • Can provide useful starting point • Have provided good lessons • Are these transport infrastructure projectssustainable? income transferred? other assets created? promoting empowerment? • Poverty alleviation projects generally short term in nature • Ongoing labour based projects required in all types ofinfrastructure projects to retain benefits from the concept • With necessary preconditions then outputs of sustainability and empowerment will be attained Economic Growth and Development Through Roads

  26. Question 2 - With stalled IDP’s can Opportunity Value Assessment (OVA) concepts offer support in underpinning road delivery? • Is there acceptance of the OVA concepts? • “We like OVA” • Requires proper weighting of social aspects • Need to separate “economic” from “social” roads • What elements should be promoted ? • OVA should be used for all elements of IDP • Standards needed for all types of infrastructure • Models and economic criteria needed • Consider link to World Bank “Rural Livelihoods Approach” • What should be done to promote OVA introduction into road provision policy ? • Promote through industry associations & CAPSA Economic Growth and Development Through Roads

  27. Question 3 - Spatial Development Initiatives in SADC require private sector involvementin corridor development • What should be done to ensure success in these SDIs & how can the role of the private sector be improved? • There must be government commitment • Policies must be conducive to corridor developmentand integrated • Suitable manpower must be available to drive the process • Scoping of potential commercial & economic developments must be done • Routes / corridors must be prioritised • Harmonisation required - axle loads / overload control • Non physical barriers should be removed Economic Growth and Development Through Roads

  28. Question 5 - Jo’burg City has embedded transport and roads provision into the goals of poverty alleviation and improved service provision • Can Jo’burg’s approach be a useful model to other municipalities in a) planning? b) with a delivery agency? and c) using turnkey procurement? • Yes to a), b) and c) - but for larger municipalities • Need to define KPI’s and budget • The Roads Agency concept within the municipality has important advantages for delivery • Need to get expressions of interest from contractors and engineers Economic Growth and Development Through Roads

  29. Workshop Overview Recommendations to Plenary • CAPSA should endorse the development of standardised economic models such as Opportunity Value Assessment to promote an holistic approach for assessment of road infrastructure projects • Workshop Conclusions need to be noted in project development Economic Growth and Development Through Roads

  30. THEME2: Efficient Road Provision & Maintenance • One Plenary Session • 2 Workshops • Upgrading Gravel Roads • Performance Based Contracts



  33. PLENARY CONCLUSIONS • Sustainability does not only require resources • Institutional Efficiency • Organisational Effectiveness • Contracting out • Planning and Design Improvements • Improved Data Collection and Analysis • Performance Based Asset Management and Maintenance (PRAMM) • Reduces Cost and Improves focus • Improves Quality

  34. Technical Tools IT, RMS Accounting Systems Performance Measurement Administrative Arrangements Organizational Reform Competition Privatization Outsourcing HR Development Owners and Customer Needs Owners Objectives Supply Chain Management User Requirements Customer Satisfaction Business Arrangements Consultants Appointments Specifications Risk Sharing - PPGS Lifetime Costing New Types of Funding PPP’s Asset Management Framework

  35. WORKSHOP 3: GRAVEL ROAD UPGRADING • 3 Papers and Discussion • Promote Concept by drafting non-technical addendum to SADC guidelines for decision makers and communities • Disseminate Guidelines • The lack of Sustainable Maintenance is cause for concern and processes should be developed that ensure this. • Driver safety should not be compromised • Road standards should be related to function

  36. WORKSHOP 7: PERFORMANCE BASED CONTRACTS • 4 Papers! - and Panel Discussion • SAFCEC’s Mentorship of SMMES and related problems • PPGS project sizes and risk allocation should be revisited • Concessionaires are becoming comfortable in their role as “road owners” • The application and use of PRAMM must be aligned to the realities of SA scene iro SMMEs • Procurement procedures and Project size and Period need to be revisited • Concession contracts must be optimized to obtain an equitable balance between • quality and delivery and • between fair compensation and profit taking.

  37. THEME3: Human Capital Development • One Plenary Session • Allyson Lawless – Invited speaker • 1 Workshop



  40. KEY FINDINGS • Tuition Language problems • Socio-economic situation • 25% of Maths teachers qualified





  45. RECOMMENDATIONS • Attract and Develop Young scientists & engineers • Provide good education at all levels • Develop Centres of Excellence • Roads Academy? • Use PPPs that involve academia • Build Digital libraries • Build networks for collaboration • Devise novel funding methods • Promote public awareness • Maintain standards • Provide rewarding and challenging opportunities

  46. THEME4: Best Practice in Flexible Pavement Design, Construction and Maintenance • 4 Sub Themes • Asphalt Technology • Cold Mix Technology • Flexible Pavement Technology • Seals and Thin surfacings • 4 Plenaries and • 6 Workshops • Asphalt Research and Design • HSE • Cold in-place recycling • Binder Specs • Surfacing Seals • Construction and Maintenance

  47. ASPHALT TECHNOLOGY • Bit spec. problems – not performance based • Bitumen penetration - changes in small samples relative to large storage volumes • HMA guideline deficiencies • Compaction not understood • Different rutting tests appear not to be comparable? • Enhancements iro permeability, stripping and deformation required • The addition of filler needs attention • Protocols for trial mixes need improvement • Aggregate Specs. - review & make provision for poorer materials in certain circumstances • Payment methods need review to promote quality • Experts are ageing

  48. COLD MIX TECHNOLOGY • TG2 Manual deficient – include latest data and curing techniques • No acceptable design method • Quality assurance difficult due to inherent variability and many specs – need better standard spec. • ITS or UCS – not both • Uniform curing protocol required • Need improved moisture sensitivity and durability tests • Grading influences on FTB vs ETB • Active filler – what is its role? • Compaction in wet areas – FTB preferable? • High RAP content appears to result in poorer performance • Some HVS testing has started to produce answers. • High binder content FTB (4%) shows good performance on LTPP • Differences between behavior and failure mechanisms • Stiffness gains as well as reductions over time! • Can carry heavy traffic

  49. FLEXIBLE PAVEMENT DESIGN • SA Mechanistic design – must understand assumptions, variability and must carry out “engineering” – needs review • Adhesion/bonding of inter-layers has major influence – how to test? • Soil mechanics neglected and CBR outdated – consider threshold stress, shakedown concepts and possibly Texas Triaxial Test • Tyre-pavement interface problems and how to model in designs - ESALS and related tyre pressure models need review • Use of FWD and GPR can provide some answers

  50. SEALS AND THIN SURFACINGS • How to obtain traffic design inputs subject to basecourse conditions • Environmental inputs and modifiers – need LTPP inputs • Aggregate Specs and other standards need to be reviewed for LVR to ensure appropriateness • Spatial composition – voids vs texture • Life-cycle costs of alternatives • UTFCs – define cost effectiveness and skid definitions and modeling? • Punching of aggregate – need appropriate models for all underlying materials
