Abstract
The aim of this project is to determine the performance of sanbase additives on weak subbase material. To achieve the aim the following objectives were adopted to collect samples from the barrow pit to perform a test with zero percent additive of sanbase (SB) to serve as a control to perform another test with percentage addition of sanbase (SB) of 0.2%, 0.4%, 0.6% and 0.8% respectively the laboratory tests to be carried out to include the natural moisture content, CBR test, compaction test and atterberg limit test, specific gravity and sieve analysis to analyse the performance of sanbase as an additive on week subbase material to present the result of our findings at the end of the research. The samples were subjected to the following laboratory test including natural moisture content, specific gravity, atterberg limit, compaction and California bearing ratio (CBR). The soil samples were subjected to the following laboratory test the natural moisture content of laterite was 3.45%, the specific gravity was 2.69% and the liquid limit with the lowest value was at 0% is 12% and the highest liquid limit at 0.8% is 19%. And compaction has optimum moisture content (OMC) which the lowest value at 0.2% is 6% and the highest value at 0% is 9.6% and the maximum dry density (MDD) with a lower value at 0.6% is 1.8g/cm3 and the highest value at 0.2% is 1.98g/cm3, while CBR test result which the lowest value at 0% is 15.60% and the highest value is at 0.4% is 26.26% respectively. Based on the short review of this study treatment of soil with sanbase additives there was an increase in the CBR value of the weak soil to become suitable for construction....
