WHAT IS ASPHALT REINFORCEMENT?
Reflective cracking can affect asphalt overlays for a few reasons. The most common of these include roads or paved areas with fatigue cracks, trench reinstatements, concrete expansion joints and subsidence.
Keeping the existing road network in an acceptable condition is one of the major challenges of road authorities all over the world. The focus of attention is, therefore, on maintenance techniques and refurbishment methods which allow the working life of the basic road structure to be extended in a cost-effective and technically reliable manner. One method which has been successfully used worldwide for more than 30 years is the maintenance of asphalt and concrete roads using geosynthetic interlayers. This method represents an economic means of considerably increasing the maintenance intervals and thus the working life of the road.
We approach every project as an opportunity to demonstrate our commitment to deliver high-quality services and products to the site.
We operate a UKAS accredited quality management systems – ISO 9001:2015 in addition to NHSS sector scheme 13 approval for the supply and application of asphalt geosynthetic and steel meshes.
What is a Geosynthetic?
It is a glass/basalt fibre grid attached to a nonwoven fabric to combine the best features of different materials.
Will a geosynthetic stop cracking?
Not completely, but if installed correctly it will substantially delay the progress of a crack and will prolong the life of the pavement.
What does the grid do?
Offers high tensile strength at low elongation to reinforce the asphalt.
What is a bitumen bond coat?
A bitumen bond coat offers excellent adhesion and saturates the non-woven to create a moisture barrier and SAMI layer.
Is a second bond coat required?
No. The heat of the asphalt overlay will draw through the fabric to create bonding and a moisture barrier (SAMI layer).
How quickly can the geosynthetic be overlaid?
Immediately after installation due to the use of straight run bitumen.
