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

• 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 IDPs 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 - Joburg City has embedded transport
and roads provision into the goals of poverty
alleviation and improved service provision

• Can Joburgs 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 KPIs 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

60
Standing items

• Variability and risk
• Health, safety and the environment
• Design of HMA
• Structural design of pavements
• Construction and delivery

61
Variability and risk

• 1969 van der Merwe
• the most important (problem with the use of
  naturally occurring materials) is their
  inherent and high degree of variability.
  (Therefore) engineers should insist on the
  gradual introduction of (probability theory).
• 1969 Monismith
• ..the scatter of results is very great in fatigue
  testing. Thus the fatigue life of a material
  can truly be represented only as a distribution
  of values for individual specimens.

62
Variability and risk/cont

• 1974 Hudson
• The consideration of variations associated with
  flexible pavement properties and design models
  through a probabilistic approach has been
  proven to be implementable into daily operations
  of a state highway department.
• 1984 Hugo
• With respect to risk it has been shown that tools
  are available to take account of variation in
  material and other parameters. Despite this we
  still have developmental work to do before the
  calculations can be done with confidence

63
Variability and risk/cont

• 1994 Molenaar
• (Pavement) performance is dependant on
• The stress level and the variations therein.
• The strength level and the variations therein
• 1999 Jooste
• Development of an accurate response model without
  the adequate definition of input variables is
  analogous to using a very expensive and accurate
  rifle without learning how to shoot.
• 1999 Strauss
• the inadequacy in the design construction and
  maintenance process to define and quantify risk

64
Health safety and environment

• 1969 Beatty
• Air pollution and dust control, which is a great
  problem in most areas of the world, is either
  here with you in SA or will be very shortly.
• 1974 Rigden
• (On the petroleum crisis) But the need to
  conserve petroleum products goes much further.
  How can we justify the continued use of cut-back
  bitumens with their wasteful evaporation and loss
  of precious volatile fractions?
• 1974 Millard
• The energy crisis has at least for the time being
  chased noise and other forms of traffic pollution
  from the headlines. But it is likely that our
  concern to reduce traffic noise will continue,
  even become more intense.

65
HSE/cont

• 1974 Terrell (On drum mixers)
• Mass viscosity (ease of handling) of the mix at
  100?C with 2 water is similar to a conventional
  mix at 150 ?C.
• 1974 Crawford
• Tar is carcinogenic and presents definite
  handling hazards to the paving crew.
• 1979 R Mitchell
• more than half of the operators in contact with
  (road tar) spraying suffer with skin irritations
  and spraying personnel have to be selected to
  handle tar from a minority that do not so suffer.

66
Design of HMA

• 1969 F Hugo
• The Marshall method of compaction does not
  produce a mix structure equivalent to the in-situ
  sample on the road after several years of
  traffic.
• 1969 Krchma
• so when we dont get a compaction in the
  laboratory corresponding to that in the field,
  the mix design is not appropriate.
• 1979 Monismith
• The general tendency is that, as you move from
  Arizona to northern Canada, you would move for
  e.g. from a 40/50 pen up to perhaps a 200/300
  pen. The softer the bitumen, the better the
  stress relaxation characteristics.

67
Design of HMA/cont

• 1979 Acott
• Despite vastly increased knowledge of the
  behaviour of pavement structural systems we are
  still using the empirical Marshall test for
  designing and controlling asphalt mixes.
• 1984 Brown
• On the basis of extensive testing on a wide range
  of standard and modified bitumen mixes, (we
  conclude that)
• Resistance to permanent deformation depends
  strongly on aggregate grading and is not
  influenced by the grade of binder
• The Marshall stability test is not capable of
  distinguishing the relative deformation
  resistance of mixes.

68
Design of HMA/cont

• 1999 Jooste
• Although (Marshall stability and flow are) widely
  purported to be empirical design parameters there
  is actually little evidence to link these
  indicators to HMA performance.
• 1999 Van de Ven
• A sound understanding of spatial composition is
  necessary to predict the effects of changes (in
  traffic loading and new materials).
• 1969 Rigden
• The challenge remains to develop a method which
  will properly account for traffic loading,
  material properties, local conditions
  (environment) and relevant for the entire scope
  of wheel loads and wheel load combinations.

69
Structural design of pavements

• 1969 Brown
• Although the validity of using linear elastic
  theory for pavement analysis is not entirely
  proven and although the calculations may not be
  exact, it is an attempt to solve the problem ...
  and...
• 1969 Grant
• Linear elastic layer theory gave an inaccurate
  prediction of where cracking would occur...
• 1969 Brown
• The only attempt to prevent shear failure in
  current design procedures is to specify a minimum
  CBR

70
Structural design/cont

• 1979 Ishai (on load equivalency factors)
• Many methods for determining load equivalency
  factors are independent of or insensitive to
  important factors
• axle load
• wheel configuration
• pavement type
• number of applications
• 1979 Monismith
• There are still problems with the proper
  definition of fatigue criteria and it is
  necessary to depend on empirical correlations
  (shifts). In addition, it is possible that the
  maximum tensile strain may not occur on the
  underside of the layer, but at some other
  location.

71
Structural design/cont

• 1979 DJ van Vuuren (on accelerated pavement
  testing)
• Although traffic stresses may not be influenced
  by increasing the rate of trafficking, stresses
  caused by environmental conditions may not have
  time to develop (and) ageing and self-healing of
  bituminous mixtures must not be lost sight of.

72
Construction and delivery

• 1969 Holzbach
• The responsibility for proper quality control can
  either taken by the road authority or the
  contractor. In a developing country like SA both
  should share the responsibility.
• 1969 Perry (Limmer Trinidad Asphalt Co.)
• 100 200mm thick lifts (of asphalt) are
  commonplace in the USA and Germany resulting in
  higher densities than in lifts of up to 75mm.

73
Construction and delivery/cont

• 1969 Hindle (on staged construction)
• Another challenge of the (19)70s is to
  determine how little we can get away with right
  now to carry present and immediate future
  traffic, such as we can come along later and
  strengthen the pavements without having damaged
  the initial work to the extent of having lost it.
• 1969 Mackintosh
• Overloading has become a matter of national
  urgency. An expression of opinion should come
  from this conference, in the form of a
  resolution, saying that we view the situation
  with grave concern.
• 1984 Floor
• Where low vehicle counts exist, a road or work on
  a road could still be justified economically by a
  thorough examination of the distributional
  effects of the work

74
Construction and delivery/cont

• 1994 Negota
• Our roads must serve to underpin not only the
  creation of wealth, but should also serve to
  assist the actual distribution of it.
• 1994 Bonnot
• To evaluate this durability or performance, the
  client will use the Avis Technique (Advisory on
  Technical Assessments)

75
(No Transcript)
76
The gaps

• Coming to grips with variability in our design
  processes and developing a stochastic approach to
  the outputs of our relatively complex analytical
  methods
• Continued use of coal tar, notwithstanding it
  being a proven carcinogen to humans and its
  adverse effects on the environment.
• Dogged adherence to the Marshall method for
  preparing laboratory samples

77
Marshall
78
The gaps/cont

• Reliance on binder hardness, rather than
  aggregate structure to combat permanent
  deformation
• Spatial composition (rather than mass based
  particle size distribution) as a descriptor of
  the building blocks of an asphalt layer.
• A single load equivalency model, notwithstanding
  a wide array of pavement types, axle
  distributions and tyre contact configurations

79
The gaps/cont

• Accounting for environmental impacts on long term
  pavement behaviour in our APT programmes.
• Equitable apportionment of risk through the
  adoption of performance warranties.
• Ad hoc technology for the design of low volume
  roads

80
Why?

• No need to change while leaders in our field have
  advised us to do so?
• Matters too complex (given the degree of
  sophistication we apply regularly)?
• Are institutions of learning sensitised to the
  deficiencies in our armour?
• No continuum of driving energy?

81
Concluding remarks

• Conference identity
• Delegate profile
• Conference structure
• Research and development
• Conference cycle

82
Conference identity

• Merger of road related conferences?
• Conference scope
• Innovate and shape technology to serve society
• Address
• road user needs,
• economic modeling
• Social impacts
• Worker safety and environmental conservation
• Technology should be contextualised

83
Conference structure

• Curtayne (1984)
• It is illuminating to trace the history of the
  development through the proceedings of these
  conferences
• Moderators employed in 69, 84, 99
• More structured recording of the proceedings
• Proceedings should ideally capture the discussion
  and debate

84
Research and development

• Rigden (1974)
• A national research organisation, financed
  partly by Parliamentary vote, is a national
  asset, provided its programmes and objectives are
  related to national needs and development
  strategies
• We have fallen behind Europe
• - do we have the capacity to redress it?
• - do we have a measure of the extent?

91
After the conference

• Resolutions (operations based) BMLC/RPF
• Gaps
• Lack of driving engine
• Declining support for research
• Focal point for career development
• Abdication by road owners to develop and nurture
  collective wisdom

92
Role of Sabita and partners

• 1979 Peter Faure
• Perhaps one could look at SABTA as an ongoing
  CAPSA a body to bridge the gap between 5 yearly
  conferences.
• Since 1987 23 manuals (15 with direct links to
  CAPSA discussion and debate)
• AsAc (JV CSIR Sabita)
• SAT founded by Sabita in 1994

93
Summary

• For 35 years now CAPSA has added value the
  intellect and long may it continue to do so.
• Refurbished RPF and revised AsAc programmes to
  advance our competency by providing continuity
• Support for development of more appropriate
  economic utility functions and fashioning our
  standards and technology to low volume roads.

94
Summary/cont

• Consider 4-year cycle with next conference in
  2007
• Moderators for plenaries and continue with
  workshops, with early focus to convenors and
  topic guidance from moderators
• Support for identification of national research
  and development needs and the rationalisation of
  programmes
• Future conferences to continue to cover HSE in
  the interests of sustainability of our actions
  and deeds
