The Applied Mechanical Stabilization Design Method for Unpaved Roads

One of the most common challenges in sitework is the efficient construction of unpaved roads, particularly over soft soils. The design of these roads was historically based on imprecise inputs or rules of thumb. In the past 20 – 30 years, improved methods have resulted in better designs and successfully incorporated the benefits of geosynthetics for stabilization.

Now Tensar is proud to introduce a new design methodology delivering significant improvements over currently accepted methods in design precision, the range of site conditions that can be addressed, and the performance contribution of granular materials and geosynthetics. This method is the culmination of a multi-year effort to address the design needs of our customers and comprehensively validate performance to support successful projects.

Presented by Dr. Andrew Lees, the originator of this radical, new method. Learn how it was developed, validated and how it brings even more value to roadway designs.

In this session, we will:

• Identify the limitations and shortcomings of existing methods, how the new method addresses these, and other advantages of the new methodDiscuss the theory behind the method and the testing and validation of the method.
• Outline the additional value the method brings to road designs by accurately accounting for different materials in the design and increased precision with design loadingsDiscuss the implementation of the design method into Tensar+ software.
• Review project examples of how this method has already saved time and money.
