Combined, these two volumes feature over 370 geotechnical and geoenvironmental standards. Volume 04.08 covers tests and practices that establish standard procedures for soil testing, including compaction, sampling, field investigation, soil texture, plasticity, density characteristics, moisture content, and hydrological and structural properties. Others focus on construction control, and ground water investigations, or detail test methods that explain how to measure the properties of soil-cement and tests for peats, mosses, and humus. In addition to the above subjects, Volume 04.09 also includes standards on surface and subsurface characterization, erosion and sediment control technology, frozen soils and rock, geotechnics of waste management, and information retrieval and data automation.
