TL;DR: In this article, the interaction between soil and reinforcement was investigated by using both direct shear and pull-out tests and applied the results to a case study on an irrigation canal bank repaired by the Public Works Department of Thailand using cohesive backfill and Tensar SS2 geogrids.

TL;DR: In this article, a permittivity probe was used to measure the electrical conductivity of the in situ soil, which was then related to sulfate content in soils, and expansion tests were performed to determine the amount of expansion that occurs when lime is added to soils with different sulfate contents.
Abstract: The addition of hydrated lime to clay soils is one of the most common methods of soil stabilization. However, when sulfates are present in the soil, the calcium in the lime reacts with the sulfates to form ettringite, an expandable mineral. This expansion causes a considerable amount of economical as well as structural problems. Sulfate related heave has been experienced along IH 45 and FM 1382. In this research, a field test method was developed to locate sulfate bearing soils. A permittivity probe was used to measure the electrical conductivity of the in situ soil. The electrical conductivity was then related to sulfate content in soils. Expansion tests were performed to determine the amount of expansion that occurs when lime is added to soils with different sulfate contents. A model that relates the amount of expansion of clay soils to electrical conductivity was proposed. The use of low calcium fly-ashes was investigated and proposed as an alternative form of stabilizer for sulfate bearing soils.

TL;DR: In this paper, the results of an investigation on the effect of five stabilizing agents, namely limestone dust, marl, emulsified asphalt, cement and lime, on the properties of an arid, saline sabkha soil from eastern Saudi Arabia were presented.
Abstract: This paper describes the results of an investigation on the effect of five stabilizing agents, namely limestone dust, marl, emulsified asphalt, cement and lime, on the properties of an arid, saline sabkha soil from eastern Saudi Arabia. Standard compaction and unconfined compressive strength tests were performed, the latter on wrapped specimens that had been allowed to cure for seven days. The results indicated that the density of sabkha mixtures could not be used as a primary criterion in any stabilization programme and the maximum strength of sabkha mixtures was attained at moisture contents much lower than the optimum. Despite the sabkha9s coarsegrained nature, neither addition of marl nor of emulsified asphalt gave any significant improvement in the properties of sabkha and the effect of adding limestone dust was marginal. However, the addition of either lime or cement in the range of 2.5 to 100y weight of soil increased the strength between and 22 times.
