Maxi-Crete F is BBA HAPAS approved. It is used extensively as a recess repair system in all highway and airfield pavements and also as a Stress Absorbing Membrane Interlayer (SAMI) on surfaces due to be overlaid, thus reducing the effects of reflective cracking.
Both Maxi-Crete F20 and F40 can be installed to any depth and width, however for depths >20mm F40 is usually advised. For repairs with varying depths F20 with its finer aggregates gives a smoother finish. By recessing into the pavement surface it will greatly prolong the service life and enhance ride quality.
Maxi-Crete F is a black, pre-mixed, hot applied, high modulus, polymerised resin compound incorporating fillers, aggregates and rubber and other mineral fillers.
2mm to 5mm aggregate (granite, basalt or bauxite) is used on the surface of the repair to meet friction and texture depth requirements or to be sympathetic to the adjacent surface colour. It offers extremely good adhesion to asphalt surfaces and is formulated to have excellent anti-oxidation properties.
In its molten state Maxi- Crete F has excellent flow properties thereby ensuring total penetration of the crack/recess. Following cooling it sets to a tough, load-bearing repair that is capable of maintaining flexibility through a wide range of temperatures, and will ensure optimum compressive resistance.
