| 20100071474 | Field Strength Test Devices and Methods for Installed Engineered Material Arresting Systems - Embodiments of the present invention provide field test devices and methods for testing the compressive gradient strength of installed vehicle arresting systems, such as those installed on airport runways. Current methods of testing such arresting systems are conducted on sample materials in-house, and these methods are not applicable or useful when tests need to be conducted on currently-installed systems in the field. | 03-25-2010 |
