CONCRETE ROAD DESIGN AND CONSTRUCTION

COURSE Overview

The course focuses on the technology applied in the design and construction of concrete pavements.     It covers the supporting layers, thickness design using computer program, cncPave, and joint design, detailing and layout.   Concrete materials and mix design, construction, modes of distress and failure and rehabilitation are also included.

Minimum entrance requirements

A degree or diploma in civil engineering is recommended.   A number of years’ experience in road design and/or construction is highly recommended.
