FEMA has recently released a new document titled “Summary of Existing Guidelines for Hydrologic Safety of Dams”. I was pleased to hear about this report from one of it’s co-authors, Amanda Hess of Gannett Fleming. […]
I’ve collected a list of new, updated and otherwise updated ASTM standards that pertain to geotechnical engineering, construction and materials testing and laboratory testing of soil, rock, geosynthetics and related fields. This month’s updates contains a new standard for measuring hydraulic conductivity of recycled tire-derived aggregate, updates to leak detection standards and more. Click through for the list of updates to ASTM standards you can’t afford to ignore in your practice.
This post contains a list of new, revised and otherwise updated ASTM standards that pertain to the geotechnical engineering, materials testing and related fields. The standards for the standard proctor and modified proctor tests have been revised. There are a number of updated standards associated with cements and mortars, and curiously several standards that have been withdrawn with no replacements, including the standard for testing collapse susceptibility of soils, one pertaining to curing of concrete, and two for testing of soil-cement mixtures. Click through to see the updates to the ASTM standards.
Geotechnical engineers, geotechnical lab managers, CQA service managers and others utilize ASTM standards on a daily basis. Here at GeoPrac.net, we monitor the periodic updates from ASTM and summarize changes to relevant standards that may be of interest to geoprofessionals. Click through for a list of revised and reapproved standards from May of 2012.
This post contains a list of new, revised and otherwise updated ASTM standards that pertain to the geotechnical engineering, materials testing and related fields. Standard C39/C39M for testing the compressive strength of concrete cyllinders was updated, as was C42/42m for obtaining and testing drilled cores and sawed beams of concrete. The month of March also saw several geosynthetic standards being updated or added, including new standards for selecting the test method for geomembrane seams, and for testing the flexural rigidity of geogrids and other geosynthetics. There are also a few updated standards related to asphalt mix design and sampling of asphalt. Click through for updated ASTM Standards relating to geoprofessionals.
This post highlights recent changes to ASTM Standards affecting geotechnical engineers, materials testing engineers, soil and construction laboratory managers and related professionals. Updates for February include: a new standard for geospatial data at coal mines; standards related to pervious concrete; an updated standard for volumetric concrete batching; and an update to D5778 – Standard Test Method for Electronic Friction Cone and Piezocone Penetration Testing of Soils; among others. Click through for the list.
Happy New Year! Here are a list of updated and new ASTM standards related to geotechnical engineering, materials testing and other subjects of interest to geoprofessionals. In this batch is a new standard for testing individual geogrid junction strength and other updated standards for geogrid testing. The standard for geofoam has been updated, so has the standard for SPT sampling. Read on for a list of these updated standards and others.
LEED Certification is a voluntary process for building owners and designers. But a newly approved green building code developed by the International Code Council titled the ‘International Green Construction Code’ or IgCC may see adoption […]
