Globa-Road-Technology-Road-Stabilization-Dust-Control  (1)Everyone talks about road soil stabilization for good reasons. Stabilization makes your roads drivable. It also makes your roads durable and environmentally friendly. However, most people only discuss it for straight level roads. While most roads meet this category, you may have a few inclined roads to deal with.

Sloped roads are more unstable than level roads, and therefore require more care in construction. They are prone to landslides, spreading out due to gravity, and erosion from running water. This instability grows with the steepness of the grade as well, and you need to the right tools and techniques to keep those sloped roads serving your needs.

Proper slope protection includes a biological and a mechanical component. Plants are natural soil stabilizers, and any good sloped road needs to use plant in some way. Soil particles stick to the roots of plants creating a strong and durable retaining wall that is erosion resistant. You want to create a dense vegetative cover for your roads to minimize the movement of the sediments. Native plants are less expensive to use and maintain, and also blend into the natural landscape, though some exotic species were cultivated for road protection. Nearby trees even act as buttress piles and abutments keeping your sloped roads usable for years. Either way, you get the soil protection you need with an aesthetics that is hard to match.

While plants work wonders, they are useless for temporary roads, and you cannot drive on the plants for them to function. For these functions, you need a chemical or a mechanical method. You need road stabilization products wherever you have deep-seated slope movement or high, lateral earth stress. However, not every stabilization products will do.

You need a product that can keep your road stable without jeopardizing the plants you use for your retaining walls. Otherwise, it will be like you never stabilized the road in the first place, reducing road safety and its aesthetics.

Mechanical sloped road stabilization uses several processes from nails to compacting to blending soils. Other techniques use woodchips, sawdust, and wood mats. Compaction lowers the moisture content of the soil, but that also lowers the available water for your retaining wall. Retaining nails get in the way of the plants roots and are only useful for the side of the roads and not the roads themselves. You need a solution that increases sediment density and lowers moisture content, but not so much that they kill the plants.

Chemical stabilizers have the same problems as well. This is why Global Road Technology only offers durable, long-lasting, biopolymer-based stabilization solutions that will not effect the environment. GRT products are universally applicable to all roads, even sloped ones, under any condition or weather. There products easily withstand UV rays, enzymes, and soil microbes, and you can use them for both cohesive and non-cohesive ground materials and filling in wet, dry, hot, and cold regions for roads of any grade.

GRT products set quickly allowing you to implement them at the same time you plant your retaining walls. This means that GRT roads are ready in hours after application instead of days or months like other methods. Plus, they have no negative environmental effects. You can use there products for subgrade and surface stabilization on even the steepest of sloped roads.
