GEOGRID REINFORCEMENT OF RAILWAY BALLAST


The railway track system forms an integral part of the transportation infrastructure of this country as well as playing a significant role in sustaining a healthy economy. However, little radical improvement has taken place since Victorian times. Maintaining good track geometry under demanding operational conditions holds the key to an efficient railway system. With a good track geometry or alignment, track will have no need for frequent maintenance, which is costly and is the main cause of train delays.

What are Geogrids?

A geogrid is a geosynthetic material used to stabilize soil. Today, Many designers are choosing to implement geogrids and Geocompopsite Materials to improve the performance of the aggregate within structures to combat increasing material costs and withstand heavy traffic loads. 

How do geogrids work? Geogrids have openings, called apertures, which allow aggregate to strike through and provide confinement and interlock. As the aggregate layer stiffens, the load distribution over the underlying ballast or sub-ballast is enhanced, increasing its effective bearing capacity. Shear forces imposed within the aggregate layer as a result of trains passing are thereby partially transferred into the geogrid. Geogrids can improve the long-term performance of tracks by minimizing aggregate movement and maintaining modulus values.
