Stabilization of Recycled Thin Bituminous-Granular Pavements with Asphalt Emulsion and Portland Cement
This paper, from the proceedings of the 52nd Annual Conference of the Canadian Technical Asphalt Association (CTAA), summarizes the findings of a pilot project investigating the laboratory and field characterization of a recycled thin asphalt pavement stabilized with asphalt emulsion and Portland cement in the City of Regina, Saskatchewan, Canada, in 2006. The authors compare cold in-place recycling to a conventional full-depth remove and replace road rehabilitation system, noting that the potential benefits of employing full-depth strengthening include: reuse of existing road materials (particularly high quality aggregate materials), a more cost effective road rehabilitation solution (particularly from a holistic cost analysis perspective), minimal interruptions to residents and business owners during construction, and minimal weather exposure risk due to a shorter construction period. The use of modern reclaimer-stabilizers enables the accurate and homogenous incorporation of various stabilizing agents during the remixing process. The authors describe their research, which employed integrated non-destructive ground penetrating radar and falling weight deflection measurements for quantifying the in-situ structural asset value of the full-depth strengthening system. They found that cold in-place recycling and full-depth cationic asphalt emulsion with Portland cement significantly improved the structural asset value of the urban streets rehabilitated. They conclude that full-depth strengthening of urban streets is a viable road rehabilitation system for the City of Regina.
