Hardware
Flexible pavement structures often fail prematurely because of progressive lateral and vertical displacement and a weakening of the aggregate base course. Tensar geogrid improves the overall stiffness of paved structures that support traffic by confining and interlocking with aggregate to create a mechanically stabilized layer (MSL). This leads to enhanced performance by minimizing maintenance and rehabilitation intervals common to flexible pavements. By decreasing aggregate fill requirements, additional truck deliveries are avoided, resulting in a more resilient solution with a smaller carbon footprint.
In addition, reflective cracking is one of the largest contributors to flexible pavement deterioration. Hot mix asphalt (HMA) pavement reinforcement can be installed to become the hidden strength in the road or other paved surfaces. Since a stiff tensile element is at the bottom of an overlay, pavement performance is drastically improved and ultimately maintenance and life cycle costs are reduced.
Tensar geogrids can help you build stronger, longer-lasting rigid pavements. Building a rigid pavement structure with a geogrid layer will reduce deformation better than extremely thick aggregate base sections. This enhanced pavement design creates a more uniform and resilient pavement structure.
Most long-term performance problems with concrete pavement are a result of poorly performing joints. Poor load transfer creates high slab stresses, which contribute heavily to distresses such as faulting, pumping, and corner breaks. Geogrids interlock with and confine the aggregate base, resulting in less deformation during construction as well as throughout the pavement&#;s life. The confinement also reduces the potential for contamination of the aggregate base with the subgrade soil. The geogrid and aggregate base together create a mechanically stabilized layer (MSL), which minimizes potential for the differential movements of the concrete surface that initiate faulting and corner breaks.
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. Tensar geogrids interlock with aggregate and create a mechanically stabilized layer (MSL) to evenly distribute the load, increasing bearing capacity and ensuring longer-term stability and performance.
Crane pads, laydown yards, storage facilities, and other working surfaces often support heavy, sustained loads. When poor subgrade soils are underneath these structures, the surface will quickly degrade beyond use if left untreated. Adding additional aggregate is a common, yet very expensive solution that is only a short-term fix. A mechanically stabilized layer (MSL) formed of multiple layers of Tensar geogrid can easily support these heavy loads. Less aggregate is required, making the construction of these surfaces more affordable by reducing up-front costs. The MSL also improves site access and reduces future maintenance.
Construction projects with large paved areas often encounter weak, wet subgrades that are not suitable to build on. Tensar geogrids interlock with aggregate and create a mechanically stabilized layer (MSL) to evenly distribute the load, increasing bearing capacity and ensuring longer-term stability and performance. In addition, pavement interlayers can be installed to combat reflective cracking and reduce maintenance.
Many large, paved areas are designed with varied pavement thicknesses directly adjacent to one another. This can cause design, construction, and maintenance problems, most significantly when water entering the pavement accumulates in the &#;bathtub&#; created by the thicker heavy-duty section. The subgrade strength decreases and the base becomes saturated, resulting in a weaker pavement in the area where the greatest strength is required. Tensar geogrid allows the site to be graded to one level, avoiding the potential for migration of water into low-lying areas and reducing freeze-thaw susceptibility under heavy-duty pavements.
As with many other surface applications, Tensar geogrids can be used to stabilize weak subgrades underneath concrete pavers. Whether it&#;s a light-duty road or a sidewalk, geogrid prevents shifting pavers and reduces the need for maintenance over time.
