AASHTO and ASTM International Agreement Benefits U.S. and Global Road Construction and Transportation

November 6, 2012, WASHINGTON – Today’s signing of an Agreement on Standards between the American Association of State Highway and Transportation Officials (AASHTO) and ASTM International solidifies coordination between two organizations working in the common interest of highway construction, safety, maintenance, and sustainability in the United States and around the world.

AASHTO Executive Director John Horsley and ASTM President James A. Thomas today signed an agreement which serves as the basis for continued mutual cooperation on the development and publication of highway construction standards.

ASTM Updates for March, 2012

American Society of Testing Materials Logo - ASTMThis 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.

ASTM Updates for April 2011

American Society of Testing Materials Logo - ASTMIt’s that time again.  Here are a collection of changes/additions to ASTM standards that are relevant to geotechnical engineers, soils labs, CQA firms and related disciplines.  There are a couple of interesting new standards available.  D7698 is a new procedure for estimation of in-place density and water content of soil and aggregate by correlation with complex impedance.  I’m not eactly sure what that is, but it sounds cool.  There is also a new standard (D7702) that provides guidance for the evaluation of direct shear results involving geosynthetics.  Read on for these and other updates.

ASTM Updates September 2010

American Society of Testing Materials Logo - ASTMLast month there were several updates to standards involving texting the flexural strength of concrete as well as updates to some masonry and dimension stone standards.  ASTM D6926 – Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus has been updated, so if you are involved in asphalt pavement testing, make sure you go and find out what the changes are. There are also a whole slew of groundwater and site investigation standards that were reapproved.

ASTM Updates April 2010

American Society of Testing Materials Logo - ASTMStandards governing the testing of tensile strength of geogrid and geotextile tensile strength are among the standards updated over the past month by the ASTM. This includes a new standard for "Determining Small-Strain Tensile Properties of Geogrids and Geotextiles by In-Air Cyclic Tension Tests". A number of standards relating to concrete including capping of concrete cyllinders for testing have also been updated. Click through for the list.

ASTM Updates September 2009

American Society of Testing Materials Logo - ASTMThis 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.
