The use of hot in-place recycling (HIPR) has developed rapidly over the past decade, although it is in use only on a limited basis. Simple heater-scarification units, heat reforming systems, and special techniques have been developed for heating, scarifying, rejuvenation, and remixing of up to 50 mm (2 in) in depth of aged old asphalt pavement to new hot mix quality overlay in one pass.

The invention concerns heating an asphalt pavement in successive stages during time-spaced intervals. This permits the asphalt to be heated to its softening temperature without being overheated, and also permits the heat to penetrate deeply into the asphalt by conduction to soften the asphalt to a substantial depth (e.g. 1 inch or more).
