Product Information Sheet Lafarge Asphalt is committed to being the leading developer and supplier in North America, of innovative asphalt products designed to optimize quality, performance, durability and sustainability. Duraphalt HM® is a heavy duty asphalt based on stone mastic asphalt technology designed to reduce wheel rut damage caused by heavy and/or slow moving vehicles. FOAM NOZZLE Product Overview Duraphalt HM (high modulus) consists of stone-onstone aggregate skeleton with a mastic comprising of mineral filler, fiber or ASM and PGAC and/or PMA asphalt cement. The stone-on-stone aggregate skeleton (gap-graded) provides excellent rut resistance against very heavy slow moving wheel loads and the mastic coats the coarse aggregate creating a very high film thickness for exceptional durability. The use of polymer modified asphalt is recommended for heavy-duty commercial and industrial applications, such as industrial estates, pots and container areas, warehouses and commercial premises. Duraphalt HM may also be used for pavement applications, where heavy goods vehicle (HGV) distress has caused damage and failures with more conventional hot mix asphalts, especially at intersections and traffic circles and areas where wheel track rutting is an issue.
