MODIFIED COLD IN-PLACE ASPHALT RECYCLING

Cold in-place asphalt recycling has been shown to be a technically sound, cost-effective, environmentally friendly method of strengthening and maintaining a wide range of deteriorating asphalt pavements. The overall process combines testing and mix design procedures, milling, processing and mixing units with microprocessor control of emulsion addition, compaction, placement of a wearing surface and quality assurance testing. It has been shown, in laboratory work and a number of Ontario projects the past three years, that modification of the cold in-place process to incorporate new aggregate results in an improved recycled binder course with closer voids and stability control, addressing observed conventional cold in-place asphalt recycling problems such as: high residual asphalt cement content (flushing); fine mix (high percent passing 4.75 mm and 75 um); rutting (low initial stability with emulsion system); and adequacy of in-place material thickness.
