Description

SOTER has pioneered some unique techniques and equipment which can increase the already known benefits of thermoregeneration, a term which embodies the Hot-In-Place recycling and repaving process. The oldest recycling discipline within the "asphalt recycling and reclaiming association". The HIP recycling and repaving as practiced with Soter-Kajima equipment consists of a single multi-step process which can correct the pavement deficiencies in the upper one or two inches of existing asphalt pavement, including minor rutting, shrinkage, cracking, revelling and oxidation. This technique provides an immediate riding surface because it re-establishes instantly crown and drainage profiles. Soter's research and development team was able to bring about the opportunity to form an association with Japan's Kajima Road Company, a world leader in special pavement technologies such as slope pavement systems, surface recycling methods, asphalt surfacing methods and super strong surface pavement methods. On the strength of this association, Soter was able to bring to Canada in 1990 the latest innovation in pavement recycling equipment, designed and built by the Kajima Road Company with the help of the giant Mitsubishi Industries. The Soter-Kajima Super Reformer II and their accompanying hot air roadheaters, now being used in Canada (Montreal, Hull, Quebec, The Citadelle), illustrate the well known inventiveness of the Japanese in their ability to successfully design and fabricate scaled down equipment. In this case they achieved their objective in overcoming the constraints of an urban environment. The Soter-Kajima Pre-heaters and the Super Reformer II can effectively be used on major highways but they have been uniquely designed to handle the confinement and complications of city streets, including blind alleys, buried services, and all other urban road support structures. The Super Reformer II and its small convoy perform their task at a continuous working speed (no stop and go) and in one lane with one pass with little traffic disruption. The Kajima Road Company's second objective was to adopt a hot air heating system. This is a uniform, time controlled and temperature limited heating process which circulates hot air of a constant temperature evenly over the road surface. The system eliminates the possibility of damage to the recycled asphalt materials through overheating, and consequently prevents the smoke and pollution associated with radiant (direct) heating methods. The Soter-Kajima Pre-heater using a kerosene or stove oil furnace as the core of the Hot Air Flow system has been successfully employed here in Canada since 1990. Thermoregeneration as practiced by Soter is capable of a continuous single pass, multistep process of heating, reworking, applying a recycling agent, redistribution of the existing pavement material and the placement of an asphalt concrete surface course. To provide this scope of work, Soter's expertise comes from using three types of A- First remote controlled hot air flow road heater.
