When you have a paving job that needs to get done, it's easy for it to either get delayed or go over budget. How do you get the job done effectively and efficiently? One option that many contractors are putting into effect are the stabilization and paving products from Tensar. Two of the most popular products they offer is GlasGrid and Geogrids. Let's take a solid look at each product and what their advantages and disadvantages are for your situation.

GlasGrid

GlasGrid is an asphalt reinforcing system made of fiberglass strands that have been coated using an elastomeric polymer in a grid structure. Every strand in the system has a very high tensile strength combined with high amounts of elasticity. Because asphalt tends to crack at low strains and deform in extreme heat, GlasGrid helps ensure that the asphalt stays in place, creating a longer lasting surface on the road. This means you don't have to spend as much time and money making repairs to your road way or parking lot.

GlasGrid Asphalt reinforcing systemGlasgrid is applied by sandwiching it in between the surface course and the leveling course in an asphalt overlay system. This creates additional strength in the road way or parking lot, because vertical crack stress is moved horizontally through the system to dissipate those stressors. Because it's laid down with a pressure set adhesive on the bottom, it's one of the fastest reinforcement systems to lay down, at an incredible 25,000 square yards per day using an average lay down machine. The material quickly adapts to special installation circumstances or local weather conditions. Even while providing exceptional strength, it can still be readily milled and used in recycled asphalt pavement operations.

GlasPave

Compared to other paving fabrics and mats, the GlasPave system delivers stronger performance, providing low strain at higher levels of tensile strength than many competitors. This is due to the elastomeric polymer coating on the fiberglass matrix, which provides a greater degree of flexibility and strength. Unlike GlasGrid's network of fibers, GlasPave provides a solid surface to help reinforce and improve your roadway's performance. Using a non-woven matrix, the GlasPave structure allows asphalt binders to penetrate and fill spaces in the fabric, which can limit how much moisture infiltrates the pavement's overall structure.

This feature helps prevent many issues that can keep your maintenance department hopping all summer long with costly, inconvenient repairs. Because moisture is unable to penetrate deeply into your pavement structure, you're able to avoid problems from cracks and degradation around changes in pavement height, preventing freeze-thaw damage as well as issues with the roadway setting unevenly and forming potholes. Two products are available, with GlasPave25 providing twice the performance of conventional AASHTO paving fabrics and mats, while GlasPave50 delivered up to four times the performance of conventional AASHTO paving fabrics and mats.

Geogrids

Geogrids provide mechanical stabilization for your road beds and paved areas, helping prevent slowdowns on the job site during wet weather and when working on unstable soils. Available in Uniaxal, Biaxal and Triax formulations, these mechanical stabilization materials handle everything from bank and slope stabilization to high traffic areas and everything in between. They perform very well, resisting breaking down even in soil pH as high as 12.

geogrids slope stabilization

Uniaxal provides slope stabilization and grade separation using high-strength high-density polyethylene (HDPE) resins. The fiber is oriented to prevent or reduce creep, even when under heavy loads for long periods of time. Biaxal works well with work platform and road stabilization, and is well known as being the original mechanical stabilization grid. Triax, the latest offering from the company, provides superior superior stabilization using triangular geometry. This Geogrid is assembled by punching triangles out of multiple orientation polypropylene sheeting. This manufacturing technique allows higher radial stiffness through the full range of degrees. It also provides better rib and junction geometry as an improved alternative to traditional methods and materials. The structure also allows for good load transference from the geogrid to the aggregate.

Which of these products will work best for your situation? You or your contractor can best determine that. But for either situation, these high-quality Tensar products provide durable solutions to get the job done on time and on budget.
