Abstract
Until recently use of ionic chemical soil stabilisers
seemed hit or miss. The paper by paige-Green and
Bennett explains that the stabilisers work only on
soils containing reactive clays. The author's findings
confirm this conclusion. It was shown that a CBR test,
which can be done in any road soils laboratory, can be
used to measure the chanqe in strength caused by the
treatment of the soil with a chosen ionic stabiliser.
South Africa is faced with a serious unemployment
problem. The World Bank and the International Labour
Organisation have shown that employment in construction
can be significantly increased by the use of labour
instead of machinery. Field trials showed that ionic
stabilisers can readily be applied labour intensively.
These stabilisers could imprpve marginal materials to
road-building standard and this could further reduce
the dependence on machinery by reducing the need to
transport quantities of high quality gravel.
