dc.description.abstract | While it is acknowledged that good transport infrastructure is a prerequisite to economic growth, the costs of providing, maintaining and rehabilitating road infrastructure over the last few decades, have soared, consuming scarce available funds. In view of increasing traffic volumes experienced worldwide as well as current economic realities, the investigation, testing and application of “alternative” new road building products, including the application of nano-technology, have become essential. The study focused on the effect of a nano-salines stabilising agent on dolomite (a so-called “problem” soil due to its susceptibility to weathering in the presence of water), particularly with regards to water-repellence and moisture sensitivity. The results described the influence of a Nano-Modified Emulsions (NME)(Nano-Silanes) stabilising agent on the plasticity index (PI), Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) between the neat and stabilised dolomite material. This knowledge on the effect of nano-stabilisers on the moisture density relationship and index properties could be used to predict the behaviour of compacted soils encountered in pavement engineering practices and assessing the suitability of so-called “problem” soils, ultimately making the utilisation of naturally available materials such as dolomite possible and practical in pursuit of providing cost-effective, safe and sustainable road infrastructure. | |
