GeoPrac and ASTM Standards Updates
ASTM standards are an important part of my geotechnical engineering practice, and keeping up with changes can be a challenging thing. Their website offers an ASTM standards tracker service that will email you a weekly update on new, revised or otherwise modified standards for your areas of interest. I try to sift through these weekly updates and provide a monthly update to GeoPrac readers that contains changes to standards (no work items) that may be of interest to them in their practice. I look at updates from the following ASTM comittees:
- C01 – Cement
- C07 – Lime
- C09 – Concrete and Concrete Aggregates
- C15 – Manufactured Masonry Units
- C17 – Fiber-Reinforced Cement Products
- C18 – Dimension Stone
- C27 – Precast Concrete Products
- D04 – Road and Paving Materials
- D18 – Soil and Rock
- D19 – Water
- D35 – Geosynthetics
- E07 – Nondestructive Testing
- E27 – Hazard Potential of Chemicals
- E44 – Solar, Geothermal and Other Alternative Energy Sources
- G01 – Corrosion of Metals
