ASTM C39/C39M – "Standard test method for compressive strength of cylindrical concrete specimens" is probably the most significant standard update for the moth of February, at least as it pertains to the geotechnical and construction industries. Also included are a number of other concrete and mortar related standards, and some changes to the E series on nondestructive testing. Click through for the list of ASTM Standards that were revised, reapproved or otherwise changed this month.
Standards updates and revisions that may be of interest to GeoPrac readers include Bulk Density and Voids in Aggregate, several updates for Dry-Cast Segmental Retaining Wall Units, a revised standard for the California Bearing Ratio (CBR) test and several for Geosynthetic Clay Liners and Lanfill Daily Covers.

This post contains a summary of geotechnical, materials testing, geosynthetic and related testing standards that were updated by ASTM during the month of September. This month there were not as many updates as the last couple, but a few that caught my eye are a new standard for measuring geosynthetic-soil resilient interface shear stiffness, a revision to the standard practice for laboratories testing concrete and concrete aggregates for use in construction and criteria for laboratory evaluation and a revision to the standard for measuring slump flow of self-consolidating concrete.
Another busy month for ASTM with 66 new, revised or otherwise updated standards related to geotechnical and geological engineering (although not as busy as last month). A couple that caught my eye include brand new standards for geospatial data requirements related to abandoned mines, a new standard for sampling of EPS or geofoam, updated standards for mortar and cement, flexural strength of concrete, LA Abrasion test for aggregates, acceptance testing of geosynthetic clay liners, electrical methods for leak detection of geomembranes with earth cover and classification of soils and soil-aggregate mixtures for highway construction purpose (AASHTO classification).
Those involved in the materials testing side of the business should take a close look at the full list as there are also a number of updated standards relating to various asphalt and and aggregate tests, capping of concrete cyllinders and other related testing standards.
For my practice, perhaps the most significant standard that was updated was D 2488 – Standard Practice for Description and Identification of Soils (Visual-Manual Procedure) which we rely on for our field USCS classifications. I’ll be curious to see what those changes entail. Click through for the full list.
Revised, new, and reapproved ASTM standards for the month of July. This month was a busy one for the various comittees with 108 standards related to concrete, geotechnical lab testing, asphalt, lab testing and other standards updated. Read on for the list.
July 23, 2009 – Engineers, architects, contractors, code officials and others in the construction industry need access to ASTM standards referenced in the 2009 International Building Code (IBC) to design, construct and regulate safe and reliable buildings. The ASTM Standards: As Referenced in the 2009 International Building Code fulfills this need in one book.
This comprehensive book contains 280 ASTM referenced standards in Chapter 35 of the IBC, including critical topics such as structural steel, concrete, masonry, wood, soil, gypsum, insulation, fire protection, fire prevention, window fall prevention devices, and other important areas that contribute to safe and quality construction.

D5434 – “Standard Guide for Field Logging of Subsurface Explorations of Soil and Rock” and D4429 – “Standard Test Method for CBR (California Bearing Ratio) of Soils in Place” are two standards revised this month that may be of interest to geotechnical engineers. Those in the construction services and materials testing business should take a look at a number of changes to relevant standards. This month there are also a few revised standards related to detection of different ions in water. I also see that there are a number of geothermal and solar standards that were reapproved this month, most of them seem to have been last modified in the late 1980’s and early 1990’s. Click through for the full list of new, revised and reapproved ASTM standards from June.
In this month’s ASTM updates, there is a new standard for determining the laboratory density of soil specimens. Not having a standard for this item was a common problem for us in our practice. The lab would give us a density on ring samples by weiging, drying and weighing again using the known volume of the rings, but there was never any standard to go with it. Other updates this month include ones related to dimension stone, fiber reinforced concrete, sulfate content of soils, and calcium and magnesium content of water.
Our monthly ASTM standards update for those in the geotechnical, geo-environmental, hydrogeology and geo-construction fields. This month there are some new standards related to structural cementitious panels, revisions to standards related to slate and dimension stone, and a reapproved standard for monitoring well protection among others.

Our monthly update on new and revised ASTM standards that relate to geotechnical engineering, materials testing, hydrogeology, geosynthetics and related disciplines. This month there are a few notable revisions, including D1452 for Auger Borings, D3385 for Double-Ring Infiltrometer and D4595 for determining tensile properties of geotextiles by the wide-width strip method. There are also a few other geotextile, groundwater, lime, masonry and terminology standards that were added or updated. Click through for the full list.
