Asphalt Reinforcement Mesh, Grids, & More


What is asphalt reinforcement?

Solution Overview

Reflective cracking is one of the largest contributors to pavement deterioration. Conventional rehabilitation procedures prescribe placing an asphalt overlay on top of the existing rigid or flexible pavement. Although this provides some additional service life, cracks are only deterred about one year per inch of applied overlay. At this rate, you will fight a constant battle with pavement maintenance that you'll likely never win. However, when an asphalt reinforcement mesh or grid is installed, pavement performance is drastically improved and ultimately reduces maintenance and life cycle costs. Tensar offers a family of pavement reinforcement products. Our team is ready to help you select the best fit for your project.

Interlayers can drastically improve the pavement's ability to resist cracks and the drainage capabilities of a road, subsequently extending the life of the road. The example above compares a pavement rehabbed without reinforcement (left) to one that uses an interlayer (right).

How Does Asphalt Reinforcement Work?

In the world of pavements, an asphalt reinforcement interlayer refers to any material or combination of materials that are used between two pavement layers to improve the performance of the pavement. This geosynthetic material acts as a moisture barrier, mitigates the spread of reflective cracking, and reinforce the asphalt to extend the pavement’s life and amount of traffic it can withstand.

All Interlayers Are Not Created Equal

There are two main types of interlayers, bituminous-based products and geosynthetics. Within these two categories, there are a large number of products, all with various pros and cons. With so many to choose from, it's important that you select the interlayer that's right for your project.


The installation will vary from product to product but is just as important as choosing the right interlayer for the dominant distress type. Installation temperatures, street grades, wind, and the staging will all have an impact on the selection of the interlayer, so planning is very important for all projects.
