Unsealed (gravel & earth) roads comprise more than 75% of the proclaimed road network in South Africa. Over the past 30 years considerable research has been carried out regarding the design, construction, maintenance, management and upgrading of unsealed roads, which has been incorporated in the revised Draft TRH 20 document. The objective of this course is to systematically work through the information in this document, with examples and practical exercises.
The course covers:
The performance of unsealed roads
