ASTM MNL40

Combined, Volumes 04.08&04.09, feature over 440 geotechnical and geoenvironmental standards. Volume 04.08 covers tests and practices that establish standard procedures for soil testing, including sampling, field investigation, soil texture, plasticity, density characteristics, moisture content, and hydrological and structural properties. Others focus on compaction, 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.

Volume 04.09 covers site characterization, ground water investigation, and statistical modeling.

Also appearing in 04.09 are specifications, tests, and practices on mechanical, endurance, permeability, and filtration properties of geosynthetics. These include standards for geosynthetic Turf Reinforcement Mats (TRM?s), designed to provide erosion protection for the design life of a project.
