The economic conditions we are currently experiencing has created a situation that provides opportunities for many industries and institutions. Institutions from Ministries of Highways and local municipalities, to private owners have created mandates to explore new systems to streamline their businesses and this extends to commerce within the construction marketplace.

Over the past 30 years, civil engineering projects have utilized geosynthetics to optimize the design and/or increase the longevity of particular systems. This includes roadway design by enhancing subgrade stabilization and more recently optimizing the trafficked structure, be it a paved or unpaved roadway.

It is common knowledge that road structures fail prematurely due to many unfavourable factors including subgrade conditions, environmental factors, traffic patterns, water infiltration and inadequate drainage, lateral displacement and weakening of base course aggregate. The unfavorable effects of these aspects can become extremely time consuming and costly to fix irrespective of regular maintenance; therefore, significant strategies are required for long-term maintenance or rehabilitation. However, such remedies are often temporary or unsuccessful because they only treat the symptom, rather than the cause of the problem.

To safeguard against these unfavourable factors, technological systems have been developed with the use of geosynthetics. However, they should be specified during the initial design stage for them to provide optimum performance during and post construction. Within roadway design, geosynthetics are commonly used for separation, filtration, drainage, stabilization, reinforcement and crack mitigation. Invariably their use in these applications improve the performance of roadway structures by extending their longevity.

In addition to improving structural performance, geosynthetics offer many other advantages including:
