Recycling / BSM technology

General information

Dates: Next dates to be confirmed.
Location: Virtual (MS Teams platform)
Facilitator: André Greyling
Presenters: Dave Collings and André Greyling
Cost: €300.00

This training module takes a ”helicopter view” of pavements, what they are, what purpose they serve, which materials are used for construction, how these materials behave in pavement layers and why roads need ongoing maintenance and rehabilitation.  It is an introductory course for those wanting to understand the basics of pavement engineering without being blinded by science.

At the end of this training, delegates will be familiar with the following concepts
  • a basic understanding of the relevant technology applicable to different pavement materials
  • the meaning of structural capacity and how it is determined
  • the leading role played by Mother Nature in pavement engineering
  • why pavements are constructed in layers using different materials
  • the characteristics of different materials that are used to construct pavement layers
  • where specific materials should be used in a multi-layer pavement structure
  • how structural capacity is affected by changing the thickness of layers
  • options for achieving the same structural capacity using layers of different materials
  • estimating the initial construction cost and life-cycle cost for different pavement structures

Laboratory Training

General information

Dates: To be confirmed
Location: Virtual (MS Teams platform)
Facilitator: Prof. Kim Jenkins
Presenter: Prof. Kim Jenkins and Wynand van Niekerk
Cost: €500.00

This four-day course will provide the attendees with the knowledge necessary to understand the laboratory equipment and procedures to determine the optimum mix design and controlling the quality of BSM during construction.  Specialised laboratory equipment from Wirtgen is used, including the WLB 10S foamed bitumen plant, WLM 30 pugmil mixer and WLV1 vibrating hammer compactor.  The course is presented by experienced practitioners.

The course is presented in 8 sections
  • Obtaining representative samples and sample preparation for mix design
  • Calibrating the WLB10 S and determining the foaming characteristics of bitumen
  • Using the WLB10 S and WLM 30 to mix material with foamed bitumen and active filler
  • Manufacturing test specimens using the WLV 1 vibrating hammer compactor
  • Curing the specimens
  • Indirect tensile strength (ITS) testing of soaked and unsoaked specimens
  • Triaxial testing to determine the shear properties of specimens
  • Reporting the results of all tests using Excel Worksheets

Loudon International and Rubicon Solutions present a four-day training course on Pavement and Rehabilitation Design for BSMs. The course focuses on the theory of pavement rehabilitation design, with practical implementation of the concepts discussed as applicable to BSMs.

The following topics are covered
  • Fundamentals of pavement materials, failure mechanisms, performance and design
  • Pavement Design Methods:
    • AASHTO Design Method
    • Pavement Number (2020) Method
    • Mechanistic-Empirical Pavement Design Method, including calculation of stresses and strains
  • Pavement performance history, including initial assessment, data processing and reporting
  • Processing, analysis and reporting of materials test data, including BSM mix design results
  • Analysis of deflections and backcalculation
  • Condition summary and formulation of design assumptions
