Heavy-Duty Roads & Surfaces
Reliable support for the heaviest of loads
Heavy-duty roads and surfaces commonly found in high-stress applications require special attention to pavement structural design and construction. They are constantly subject to extremely heavy wheel loads and must be designed to support large loads from truck traffic, cranes, and other cargo transfer equipment. These pavements serve a variety of critical markets, including intermodal, port and loading facilities, airport runways, warehouse/distribution centers, and heavy truck corridors.
The frequent heavy loads imposed on pavements of intermodal and warehouse/distribution centers already wreak havoc on maintenance budgets. But now, diminishing and costly aggregate supplies, tightening construction budgets, and heavier wheel loads have forced engineers, contractors and owners to explore lower cost alternatives to traditional methods of construction. In addition, engineers and contractors are increasingly asked to balance the unique project requirements associated with heavy-duty roads and surfaces with environmental concerns. Modern heavy-duty pavement designers and contractors use Tensar geogrids to balance all these factors with ease.
Improved Design Life & Bearing Capacity
Heavy-duty pavements often deal with slow moving or even static traffic loads with ultra-high load magnitude. They also often surround facilities with large parking/paved areas, high traffic zones, laydown areas, equipment yards, construction site entrances, storage lots, and other heavy-use areas.
By integrating Tensar geogrids into heavy-duty pavement designs, it is possible to extend the design life of heavy-duty pavements by a factor of three to six times, leading to significant lifecycle cost savings. The load-spreading capability of Tensar geogrids can also be used to increase the bearing capacity of heavy-duty pavements as well, so you can trust that your road will hold up to the loads it needs to support.
Haul and Access Roads
An estimated one-half of all roads in the United States, and an even higher percentage of roads throughout the world, are unpaved. Many of them serve as heavy-duty access and haul roads for critical industries, including mining operations, highway construction, power generation and water treatment plants, wind farms, oil drilling, refining and storage sites. A failed road can be disastrous.
Weak subgrades pose the greatest challenge to the performance of an unpaved access or haul road. Left untreated, a weak subgrade subjected to continuous heavy traffic will quickly deform, causing the road surface to rut, pothole, “washboard,” and ultimately deteriorate beyond use.
Incorporating Tensar geogrids in unpaved haul and access road construction results in a more cost-effective use of materials that saves time and money; dramatic cost savings can be realized.
The Power of Geogrids
For stabilizing aggregate, especially over weak subgrades, stiffer is better. Tensar’s technology and expertise in ground stabilization not only improve site performance, but are proven to reduce costs and environmental impact. Our innovative geogrid solutions provide effective confinement of granular fill, resulting in a stiff mechanically stabilized layer (MSL) capable of controlling differential settlement and increasing bearing capacity.
With Tensar geogrids, you need less aggregate to stabilize your job site – and less aggregate means less cost. They’re fast and easy to install, which means less time lost from your project schedule. And Tensar geogrids are backed by thousands of hours of testing and research, so you can trust the results.
