Rock and Soil Mechanics
Dispersive clay is a type of water-sensitive soil, which has the characteristics of dispersivity and material loss when encountering water. The influential factors and modification mechanism of dispersive clay modified by calcium lignosulfonate (CL) were studied using dispersivity test, mechanical property test, chemical property test, microstructure test and simulated rainfall scouring test. The test results indicated that with the increase in CL content, the dispersivity, slake durability and erosion resistance of the modified soil were gradually improved, and it had a good modification effect when the CL content reached 3.0%. The unconfined compressive strength (UCS) first increased and then decreased, …

As the State of California continues to grow, demand for enhanced infrastructure such as roadways and highways escalates. In view of the current average highway lifespan of 15–20 years, the improvement of asphalt binders leads to material sustainability by decreasing required maintenance and increasing the lifespan of roadways. In the present investigation, enhancement of asphalt binder properties was achieved by different methods of mixing varying compositions of graphene nanoparticles with an SBS polymer and asphalt binder. Additionally, experimental evaluation and comparison of the rheological and mechanical properties of each specimen is presented. Graphene nanoparticles have attracted great curiosity in the …

The production of sulfur concrete (SC) from its ingredient materials requires controlled heating and mixing conditions at a temperature level of 130°-150 °C. Although this process considered to be common and applicable at the industrial level, it is difficult at the laboratory/research level. This paper presents the design and manufacturing details of a relatively inexpensive laboratory machine for heating and mixing sulfur concrete. The different components of the machine are described in detail to help researchers to produce high-quality sulfur concrete. In this work, the quality of the machine is verified through experimental testing of the physical and mechanical properties …
