Revision of publications - progress New TMH on surveillance methods: Guidelines for Network Level Measurement of Road Roughness – draft May PAWC TRH 12 Guidelines for Pavement Rehabilitation Draft by end May SANRAL

Revision of publications - progress TRH 4 Structural Design of Road Pavements Revision of SA mechanistic empirical design method – PRAC H. Theyse – work proposal prepared for SANRAL Development of a new design method proposal by Dr F Jooste

Revision of publications - progress TRH 20 Structural Design of Unpaved Roads TOR prepared to be advertised for tenders – NDOT TRH 8 Traffic counts Guidelines for bitumen stabilised materials (FB and ETB)

COTO RMC Issues: Lack of formal structure for approvals and publishing of documents - Road Coordinating Committee (RCC) not functioning Lack of national research fund Need for other COTO committees to be reactivated.

COTO RMC Points of interest New procurement system for professional services: Competitive selection on balance between competence and price Preference for accredited laboratories Request for a QMS from consulting engineers (ISO 9001 or similar) Reactivation of COLTO specification committee – compatibility with CIDB requirements and revision

COTO RMC Next meeting: October 2006
