NEW DEVELOPMENTS IN HOT IN-PLACE RECYCLING OF ASPHALT PAVEMENTS
Recycling of asphalt pavements has become a widely accepted practice, particularly in North America and Europe. Several technologies have emerged to fill the various rehabilitation needs, depending on local conditions, type of pavement and the future of the roadway. Hot in-place recycling (HIR) technology has been developed and put into use in Canada, where highway agencies have embraced the concept and equipment manufacturers have provided innovations. This paper briefly describes the development and special characteristics of the various HIR processes. It describes the development of a new heating system that combines recirculating hot air with low-level indirect infrared components. In addition, a stirring mechanism has been incorporated in the heating system, to ensure hot air is reheated, and then incinerated, thereby providing a significant improvement in air quality compared to previous generations of HIR equipment.
