Pavement engineers are often charged with delivering a high-performing design on a small construction budget. With client expectations increasing and roadway maintenance budgets steadily declining, “miracle worker” has become a major part of the job description. It’s obvious that conventional design methods are no longer cutting it. However, forward-thinking engineers are gaining traction with a pavement optimization strategy that delivers the best performing roads for the lowest cost.
So, what is pavement optimization? It’s an innovative concept in pavement design that gives the designer the ability to adjust the design to meet requirements as efficiently as possible. Here are some examples:
1) Optimize for initial cost: Significantly reduce the pavement thickness --> Get the original design life but save on initial costs
2) Optimize for (cost neutral) pavement performance: Slightly reduce the pavement thickness --> Get significantly longer performance compared to the original design life and pay the same initial cost
3) Optimize for life cycle cost: Use the same pavement thickness --> Pay more up front on the construction but greatly reduce life cycle cost.
A geogrid is a geosynthetic material used to stabilize soil. Today, more pavement designers are choosing to implement geogrids to improve the performance of the aggregate within pavement structures to combat increasing material costs, withstand increasing traffic loads and inadequate pavement structures created with traditional pavement sections.
How do geogrids work? Geogrids have openings, called apertures, which allow aggregate to strike through and provide confinement and interlock. Geogrids can improve the long-term performance of paved and unpaved roadways by minimizing aggregate movement and maintaining modulus values.

Tensar TriAx Geogrid has been tested extensively to ensure
long-term performance and value.
Your reputation is at stake anytime your stamp is used on a design. At Tensar, we don’t take this lightly. That’s why we have invested extensively in research and testing of our TriAx Geogrid, proving its design and performance parameters time and again. You can use your stamp with confidence every time TriAx Geogrid is specified in a design. Don’t risk using products with unproven technologies.
