A spatial assessment was conducted in the semi-arid area of South Africa, to: (1) identify priority areas for the conservation of river and groundwater ecosystems; (2) examine surface and groundwater quality for human ...
Pavement materials are subjected to high-cycle loading regimes. Conventional design methods employ the Palmgren-Miner damage hypothesis to predict the fatigue life of pavement materials. The material itself is usually ...

The GDPTW makes extensive use of instrumentation in their Accelerated Pavement Testing (APT) and Long Term Pavement Performance (LTPP) programmes. In order to remain at the forefront of technology, this project investigates ...
The data required for a road materials database was identified and a basic structure formulated during 2003. A set of Excel workbooks and associated worksheets was developed as a foundation for the database and as an interim ...
This document describes the implementation of the Gautrans LTPP protocol. Three LTPP sections at existing HVS test sites have been located and market out in accordance with the LTPP protocol developed for Gautrans. Much ...
This document describes a protocol for establishment and operation of long-term pavement performance (LTPP) sections, including those linked to HVS tests. This is detailed under the following headings: Linking LTPP to ...
