The inspector plays a vital role on every construction project ensuring that the completed operations comply with the plans and specifications. Recognizing that many agencies were inexperienced in performing cold planing and the maintenance operations that utilize cold planing, and hesitant to add the treatment to their pavement management systems because of their lack of familiarity, the Asphalt Recycling & Reclaiming Association worked with FHWA to develop the Basic Asphalt Recycling Manual (BARM) and a series of best practice guidelines.
Copies of the BARM can be obtained at www.arra.org. Information on where to obtain the best practice guidelines and additional CP resources can be found in the Additional Resources section. As with any construction process, if the owner agency is concerned with any part of the process, the owner agency should have a conversation with the contractor.
CP is most often used as a surface preparation or grade preparation for other maintenance/rehabilitation techniques such as Hot In-Place Recycling (HIR), Cold Recycling (CR), Full Depth Reclamation (FDR), or asphalt overlays. Detailed information when CP is used with HIR, CR and FDR can be found in their respective sections. The following inspection guidelines refer to CP alone or when used for preparation for an asphalt overlay. Inspectors can help achieve a satisfactory project by ensuring that the process is in accordance with the contract documents as follows:
Surface Preparation: Walk or drive the entire pavement section to be milled or micro milled for the day to ensure the surface has been properly prepared and that all pre-construction repairs have been performed.
Acceptable Weather: Check conditions for anticipated heavy rainfall and freezing weather to determine if construction can start/continue.
Traffic Control: Verify that the proper traffic control is in place to keep the traveling public safe and piloted around the work area.
