ASPARi trip to South Africa


1 April 2008

In May 2008, Seirgei Miller and Andre Doree went to South Africa to present ASPARI's approach and projects. Invited by the Society for Asphalt Technology they gave talks in Durban, Cape Town & Pretoria. Lectures were also given at the Cape Peninsuala Univ of Technology and at Stellenbosch University.

The South African Society for Asphalt Technology (SAT) invited Prof. Andre Dorée and PhD candidate Seirgei Miller to conduct a series of seminars in Durban, Cape Town and Pretoria. ASPARI was asked to share its research and practical experience regarding its attempts to professionalize the asphalt paving process. Lectures were held at the Cape Peninsula University of Technology and Stellenbosch University and meetings with key role players in the asphalt industry (SABITA, SAT, contractors) in order to set up industry, student, staff and knowledge transfer opportunities for both South Africa (SA) and The Netherlands (NL).

The seminars and lectures entitled "The asphalt paving process - new tools and technologies for process monitoring and control" were enthusiastically received by all attendees. They provided a state of the art into the use of new tools and techniques in the monitoring of the asphalt paving process. It covered the following aspects:

  • Use of GPS (Global Positioning Systems) to monitor and improve compaction processes
  • Use of animations to analyse explicit operational behaviour
  • Use of infrared technology to measure and improve asphalt temperature homogeneity
  • The development of off-the–shelf, affordable GPS systems
  • State of the art technology used in the asphalt paving process – a global perspective
  • Performance monitoring & control and its effect on new contracting policies, performance contracting, longer guarantee periods and risk transfer – The Dutch experience

The itinerary for the trip

Day Date Activity
Tues 15 DURBAN: Conduct Society for Asphalt Technology (SAT) Seminar Convenor – Craig Bradley [14h00]. About 30 people attended the meeting. At the close of the meeting and over snacks some debate was raised about the current heavy work load and the difficulty to get skilled personnel in South Africa.
Wed 16 CAPE TOWN: Meet with Julian Wise, Ockert and Jonathan Pearce (Zebra Bituminous Surfacing) to discuss the development form the contractors' perspective on current state of affair in the industry en on driving quality and skills development. Furthermore: to explore transfer opportunities between SA and NL.
Thurs 17 BELLVILLE: Cape Peninsula University of Technology - Meet with Ms. Ashaadia Kamalie – Head of Civil Engineering & Dr. Oswald Franks – Dean of Engineering [09h00].
PINELANDS: Meet with Trevor Distin and John Onraet at the SABITA.)[14h00] offices to explore further knowledge transfer opportunities between SA and The Netherlands. Also, the potential for official industry visits to and from both countries was discussed and will be explored from both sides.
Fri 18 BELLVILLE: Lecture at the Cape Peninsula University of Technology [10h00]. Approximately 120 students from the Civil and Mechanical Engineering Departments attended the lecture.
Mon 21 STELLENBOSCH: Lectures for post- and undergraduate students at the University of Stellenbosch & meet with Prof. Kim Jenkins to explore student and staff transfer opportunities between ASPARI and the University of Stellenbosch [10h00]. Approximately 30 students from the Civil Engineering Department attended the lecture.
Tues 22 CAPE TOWN: Conduct Society for Asphalt Technology (SAT) Seminar - Convenor – Graeme McGregor [13h00]. 85 delegates attended the seminar. Several questions were raised relating to the practical implications of implementing process monitoring and control in a South African context. The rather astronomical cost of the high-end DGPS equipment was raised as a potential obstacle to implication. The cooling rates of the two-layer porous asphalt and lessons for other asphalt layer's cooling rates generated some discussion.
Wed 23 PRETORIA: Conduct Society for Asphalt Technology Seminar Convenor – Basil Jonsson [14h00]. 95 delegates attended the last seminar. Once again, several questions were raised relating to the practical implications of implementing process monitoring and control in a South African context.
