This guide was issued to provide guidelines for construction of the geosynthetic reinforced soilintegrated bridge system (GRS-IBS). Refer to Geosynthetic Reinforced Soil Integrated Bridge System Interim Implementation Guide for GRS-IBS design and construction guidelines. This guide serves as the technical basis for agency-developed standard specifications. Local experience and practice should be incorporated as applicable. [Source: FHWA. Image: FHWA]

Dr. Robert M. Koerner has recently published the 6th edition of his industry standard text, Designing With Geosynthetics. He changed to a small publishing company to bring down the price, and the result is a […]
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.
