Use & Purposes
In the application of base reinforcement there is the design intention of improving the bearing capacity of an existing subgrade by including a geogrid (or layers of geogrid) over the in-situ subgrade to minimise the amount of granular material needed in the base course (or pavement) design. In some situations there may be a requirement to increase the service life of the pavement by the inclusion of a geogrid for a fixed pavement depth.
The preferred geogrid in such applications is a biaxial “stiff” high modulus product. Global Synthetics are able to offer Secugrid® which is a low strain biaxial (equal strength in both directions) geogrid with higher strengths than most other geogrids at strain levels of 1%, 2% and 5%. Stiffer geogrids pick up load more quickly and consequently operate at strain levels appropriate to pavement performance levels.
To assist you in your design, this software has been designed to allow a generic calculation of aggregate base material in unreinforced and Secugrid®, reinforced applications, such as under roadways, access/haul roads, parking lots or similar applications. Secugrid® geogrid reinforcement extends project service life, improves performance, reduces excavation, and lowers overall costs. SecuCalc 2.2 is based on test trials and 30+ years of engineering knowledge. For further information click here:
