SECTION 417 – ASPHALT PAVEMENT USING RECYCLING TREATMENTS
417-1 DESCRIPTION. This specification includes two processes for in -place recycling asphalt
pavements: heater scarification (HS) and hot -in-place recycling (HIPR). The asphalt pavement surface is heated using specialized equipment to soften the asphalt. In the HS process, the softened asphalt pavement surface is scarified to a specified depth as detailed in the contract documents. The scarified asphalt pavement is then mixed with a recycling agent that rejuvenates the asphalt. This mix is then placed and compacted back onto the roadway. The scarified l ayer must be overlaid. In the case of the HIPR, the multi -step recycling process of the existing pavement includes heating, milling, and adding a recycling agent to rejuvenate the asphalt; then mixing, placing, and compacting the mixture. The resulting recycled pavement does not require an overlay. If the contract documents require the addition of virgin asphalt 19.0 mix during the HIPR process, then the resulting pavement will require an overlay.
417-2 Materials
417-2.01 Recycling Agent. Use a recycling agent specifically designed as a rejuvenator meeting the
requirements outlined in Section 702 – Bituminous Materials , 8. Asphalt Recycling Agent, Table 702 -9 Recycling Agent or Table 702 -10 Emulsified Recycling Agent . At the start of and during production, provide certified test results and documented quantities to the Engineer for each shipment of recycling agent. The use of any other grade of recycling agent or other product requires prior approval from the Direct or, Materials Bureau. A minimum 2 -week notice is needed for this approval.
