Geogrid reinforced soil slopes, gabion retaining walls, erosion control blankets and other geosynthetics are being used to construct the world’s largest human form sculpted into the landscape on a project known as Northcumberlandia. The woman sculpture is the centerpiece of a public park near Cramlington, in the north of England. The site is located adjacent to a surface coal mine, and the byproducts of the coal mining were used to construct the landform. A cover story in Geosynthetics Magazine a few months back featured the project, and the design aspects of the RSS and gabion walls that were use to form some of the woman’s more challenging features such as the chin, nose, and eyebrows.

ASTM Updates for March, 2012
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.
