ACKNOWLEDGEMENTS This manual was originally prepared by a team from VelaVKE Consulting Engineers, led by Simon Kotze and assisted by a number of persons in the industry. Their contribution is gratefully acknowledged. The manual has subsequently been edited by Dave Wright to take into account the changes in requirements for certification of binder distributors as set out in SANS 3001-BT20 to BT24. This manual is published under the auspices of the Road Pavement Forum task team on binder distributors. vi
INTRODUCTION This document sets out procedures to ensure that a binder distributor is functioning properly and capable of delivering the required application of binder uniformly during construction of bituminous seals and other spray applications. The procedures essentially include two parts: i) Distributor calibration at a testing facility on an annual basis, and ii) On-site check procedures prior to allowing the distributor to spray binder on the road surface to ensure that the distibutor is still likely to operate within calibration limits and that a uniform application can be achieved. Procedures are to be in place to ensure that binder application discrepancies are quickly detected and recorded and that the appropriate action is taken to remedy the fault in the distribution process. NOTE The reader should note that there are also a number of safety and risk assessment procedures to be followed during loading, heating and application and disposal of bituminous binders to ensure that binder distributor operators, site staff, equipment and the environment are not unduly exposed to incidents of loss of life, injury or damage. While these measures are crucially important this document will focus only on best practice pertaining to the performance of binder distributors and process control with respect to the application thereof. The reader is referred to Sabita Manual 8: Guidelines for the safe and responsible handling of bituminous products for best practice in the safe handling of binders. 7
