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!
Standards 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.
