Pavement Reinforcement / Improvement

Everyone knows infrastructure could use a little help, to say the least. Our highways and rural connector roads are now fading into disrepair in many places, and it’s becoming increasingly expensive to maintain a quality road structure.  When cracks and potholes form, contractors are often hired to repave afflicted roads with a fresh overlay of Hot Mix Asphalt, but merely applying a new overlay is somewhat like applying a Band-Aid to a deep wound, especially when reflective cracking can cause serious damage to new repaved roads in a short amount of time. On pavements repaired with merely a new overlay, cracks can return at a rate of one inch per year, requiring yet more repair work and long-term maintenance to be done.
 
That’s why engineers are working to improve interlayer technology that can arrest the spread of reflective cracking, lengthening the overall lifespan of a road while reducing routine maintenance work on fixing potholes and cracks.
Using a proven interlayer comprised of a grid structure made from fiberglass strands coated with an elastomeric polymer can greatly increase tensile strength and create a higher modulus of elasticity that works to prevent the spread of reflective cracking in pavement. These interlayers have proven to be effective in a diverse array of geographic regions, from hot, dry deserts to cold, wet subarctic areas, and it’s demonstrated a real ability to reduce the rate of return cracking.

Waterproofing roads adds an extra layer of durability, these types of interlayers use this technique to make for maximum road lifespan elongation. Unlike typical fiberglass Interlayers , where the fibers are formed into a grid, the fiberglass strands in these waterproofing materials are formed into a mesh and embedded into high performance polyester mats. This creates a matrix system that allows an asphalt binder to penetrate through the mat, sealing the pavement off from moisture that likes to seep into the road, eating away at pavement and exacerbating reflective cracks, sometimes damaging pavements down to the granular base coarse or even the subgrade.
