The paper presents an experience with soil±cement in a research project to investigate alternative pavement systems. The Portland Cement Association procedure was followed to design the soil–cement mixes. To assess the obtained material, it should satisfy durability and compressive strength criteria. As no freezing is experienced in this region of the world, it was decided to concentrate on wet–dry durability. This test is time-consuming and depends to a great extent on the skill and consistency of the operator. This might affect its reliability and reproducibility. To overcome these shortcomings, this paper proposes to substitute the weight loss from the test as a criterion with the strength of soil±cement samples, prepared in the same way as required by the standard procedure and subjected to cycles of wetting and drying. The results obtained appear to encourage the pursuit of this concept, which might, hopefully, serve the soil–cement industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
