Tensar is giving away a $500 Amazon gift card as part of their SpectraPave Design software challenge. All you have to do is download the free software for design of geogrid subgrade improvement beneath pavements, watch the tutorial video and take a quiz. Then, Bam! You are entered into the giveaway drawing. You might want to check the rest of their rules though. Oh, and the contest ends on March 31, so don’t wait!
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.
