The Pakyong Airport in Himalayan state of Sikkim in North East India was selected as the 2012 International Project of the Year by Ground Engineering Magazine, a geotechnical engineering trade publication associated with the UK’s New Civil Engineer organization. The highlight of the challenging Rup2560 M (£31M, US$48M) project is a series of geogrid reinforced slopes up to 74 m (243 feet) high. Maccaferri’s Terramesh, Green Terramesh and Paralink soil reinforcement products were used extensively on the project. Mott Macdonald India was the main designer, and Punj Lloyd of Dehli was the contractor. Maccaferri Environmental Solutions Pvt Ltd was the division of Maccaferri responsible for the reinforced soil works. [Source: geosynthetica.net. Image: Geosynthetica]

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.
