Abstract

This study aims to use portable turbidity meters in developing a quick dispersion ratio test (DR, %) to be used as an index of soil stability and erodibility. The work investigates; the use of many stabilizers (Bitumen, Lime and Cement) in the preparation of many artificially stabilized lead contaminated soils; the measurement of the scouring depth (SD, mm), critical shear stress (τc, pa) and then the erodibility coefficient (kd, cm3/kN.s) by a “Mini” Jet Erosion Test. Finally, the comparisons between the erodibility coefficient and dispersion ratio (DR, %) values of soils, as estimated by a portable turbidity meter and by the gravimetric method. The results showed that all stabilizers can markedly improve the stability of soil. In general, good correlations were found between the turbidity (NTU) and suspended solids (mg/l) of the stabilized soils (R= 0.99, 0.96 and 0.97) for bitumen, lime and cement respectively. The turbidity DR (%) appears to have a high correlation with the stabilizers percentages and with kd of soils. This study proved that the turbidity DR (%) is a cost-effective method and can be easily utilized as a successful index of soil stability. Because this method is simple and quick and of reliable results, it may be recommended to be used in estimating the stability and then erodibility of Iraqi soils depending on a classification system developed according to the findings of this study.
