Tensar asphalt reinforcement products provide long-term cost savings compared with traditional methods to improve crack mitigation and fatigue life performance. Reinforced Asphalt Overlay Applications FATIGUE Life Extension Unreinforced asphalt In a reinforced asphalt layer, the Tensar AR geogrid interlayer will delay the development of fatigue microcracking by absorbing traffic induced strain. The geogrid interlayer will either increase the fatigue life performance of the asphalt layer, or will allow the asphalt thickness to be reduced to achieve equivalent performance. Geogrid reinforced...

THERMALLY INDUCED REFLECTIVE CRACKING Thermal reflective cracking in pavements is caused by daily or seasonally peak tensile strains that occur over existing thermal cracks in the underlying layers. Independent research at the University of Nottingham has demonstrated that Tensar geogrid reinforcement protects the tensile weak asphalt layer from the thermally induced tensile strains, controlling thermally induced reflective cracking. Tensar AR reinforced Surface Strain The University of Nottingham* thermal crack simulation apparatus was used in this investigation. Two concrete slabs, each 1...

Tensar provides products within three categories of asphalt reinforcement: TENSARAR-G AR-G is a composite interlayer comprising a punched and stretched polypropylene geogrid thermally bonded to a fabric backing. The fabric backing facilitates installation and provides a long-term sealing effect -once saturated with bitumen. Owing to the 3-dimensional geometry of the geogrid, the new asphalt layer is mechanically interlocked into the geogrid's wide apertures, thus providing reinforcement, stress relief and sealing functions. TENSAR GLASSTEX Glasstex is a composite interlayer comprising a...

Mastic Interlayers Paving Fabric Interlayers TENSAR GLASSTEX®PATCH™ GlasstexPatch 880 consists of a glass yarn grid combined with a polymer modified bitumen membrane. The underside of the GlasstexPatch 880 includes an adhesive coating, while the upper side is treated with a protective layer of quartz sand. The adhesive layer is protected during storage by a peel-off release film. GlasstexPatch 440 consists of a polymer modified bitumen membrane that is treated on the surface with a quartz sand, and the underside is coated to protect the product for storage and handling. GlasstexPatch does...

Installation of GlasstexGrid RN is straightforward. Tensar asphalt reinforcement can be installed either manually or using a dedicated mechanical installation device. GlasstexPatch 880 can be applied to most sound substrates utilising the adhesive coating. Tensar AR-GN bonds well on to the underlying surface to allow paving directly over the grid. A simple overlap joint for Tensar Glasstex. Refer to installation guidelines for specific overlap instructions.

Mechanical installation of Tensar Glasstex is fast and efficient – an experienced crew can install up to 12,000m2 per day, per tanker. Paving takes place directly over the Tensar AR-GN GlasstexPatch 880 can be applied to where localised treatment is needed for the control of reflective and fatigue cracking. Tensar AR-GN can provide resistance to fatigue cracking and minimise fracturing due to long-term differential movements in the subgrade.
