Tensar HX-AE is Tensar’s most advanced high performing asphalt interlayer product. The product is a composite, comprising a stiff high-profile 3D structure consisting of continuous and non-continuous ribs forming three geometries- hexagon, trapezoid and triangle thermally bonded to a non-woven paving fabric. This provides the triple interlayer functions of reinforcement, stress absorption (SAMI) and interlayer barrier (waterproofing), once saturated with bitumen during installation. Tensar HX-AE is a proven solution for reinforcing asphalt overlays to enhance fatigue performance, e.g. increasing the life of reconstructed pavements or reducing asphalt layer thickness in new pavements.
It has also been designed to provide optimal performance for control of reflective cracking in asphalt overlays, and longitudinal cracking in road widening. The paving fabric component, after saturation with bitumen during installation, provides a stress absorbing membrane effect (SAMI) by enabling lateral strain distribution between the cracked layer and the overlay. This, together with the asphalt reinforcement effect of the grid, provides optimum crack control.
Typically installed under the asphalt binder course or the asphalt base course layers, the Tensar HX-AE interlayer’s stiff monolithic reinforcing grid mechanically interlocks with the aggregate particles in the asphalt mix to provide reinforcement-restricting lateral strains within the asphalt matrix. The multi-axial grid structure provides crack control in all directions.
The reinforced layer created prolongs service life, by offering incredible resistance to reflective cracking and mitigating longitudinal cracking caused by differential settlement between new and existing lanes on widened roads. It can also reduce surface rutting, particularly in low stiffness asphalt mixes subjected to slow and heavy wheel loading at high temperatures.
