I’ve been very impressed with the geotechnical group at the Ohio DOT. They seem to be on the cutting edge of using modern technology to manage their geotechnical data. A few years ago, I posted about a presentation that described efforts to create and implement a geotechnical data management program at ODOT. Thanks to a colleague of mine (Thanks Sanjay), I found some more recent presentations at the EarthSoft website describing the work for ODOT. EarthSoft is the maker of the Equis family of database products, which is the key component of ODOT’s system. I’m pleased to see that ODOT is also using gINT for boring log and fence diagram output from the Equis managed database. [Source: Earthsoft]

ASTM Updates September 2009
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.
