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)

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.

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• Soil mechanics neglected and CBR outdated – consider threshold stress, shakedown concepts and possibly Texas Triaxial Test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

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

• 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.

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.

HSE/cont …
• 1974 Terrell (On drum mixers)– Mass viscosity (ease of handling) of the mix at 100C
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.

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 don’t 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.

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.

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.

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

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.

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.

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.

• 1969 Hindle (on staged construction)– Another challenge of the (19)70’s 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

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

Why?

• Matters too complex (given the degree of sophistication we apply regularly)?
• Are institutions of learning sensitised to the deficiencies in our armour?

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

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?

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
