RPF Resolution May 03

• To review the process of binder distributor
  certification as fit for purpose investigate
  scope of a system for self regulation

3
Progress to date

• Draft document compiled to replace TMH 2 to
  ensure that
• binder distributors are properly calibrated
• there is a high propability that the correct
  application of binder will occur during spraying

4
Draft Document contents

• General requirements for binder distributors
• Calibration requirements at an accredited testing
  facility
• On-site tests and procedures

5
Outstanding issues

1. Compliance of test methods (which need to be
   conducted at an accredited facility to obtain a
   Calibration Certificate) to SANAS requirements
2. Correlation between Fixed pit transverse
   calibration test and the on-site bakkie test

6
Transverse Distribution Tests

• Fixed pit

• Bakkie test

7
Bakkie Test(3 nozzles per trough)
8
Way forward

• Publishing of recommendations
• Bakkie test method on CSIR website
• Drafting interim guideline (TG 3) to incorporate
  recommendations until COLTO reactivated
• Develop computer programme to correlate fix pit
  transverse distribution with Bakkie test

• Develop on-site carpet test for high profile
  
• projects
• Develop a new frame work for Distributor
• Calibration

Outstanding issues

1. Compliance of test methods to SANAS requirements
   which needed to be carried out at an accredited
   facility to obtain a Calibration Certificate
2. Correlation between Fixed pit transverse
   calibration test and the on-site bakkie test
3. The future role of Provincial Road Authorities
   wrt calibration testing and accreditation of
   Distributors

Concluding remark
End

• The Calibration certificate is no guarantee of
  accurate and uniform spraying quality and on-site
  tests will need to be carried out to improve the
  likelyhood of success.
