If mixture properties do not meet the properties in Table 405-3, work may be suspended until proper corrective actions or adjustments can be made. This may include but not be limited to changing production rate and the amount or type of recycling agent or other additives. Milling Depth. Check and record the nominal depth on both outside vertical faces of the cut at 700 feet (210 m) intervals. Compaction and Density Requirements. Compaction and Density requirements will be determined using the test strip method. Compact cold recycled material to a minimum of 97 percent of the target density obtained from test strip. Construct test strip, establish target density, and monitor density during construction in accordance with MT 219, Control-Strip B Plant Mix Paving with the following exceptions: – Construct test strip when pavement temperature is 68 °F (20 °C) or higher; Construct test strip at a depth representative of the project; and Construct test strip using rollers specified in Construction Requirements, part 2) f). If mix proportions, weather conditions or other controlling factors change, the Department may require construction of additional test strip(s) to establish a new target density. Cold Recycled Surface Slope / Smoothness. Use a level to check the cold recycled surface cross slope regularly during placement. Ensure the smoothness varies less than 0.25-inch (6 mm) from the lower edge of a 10-foot (3 m) straight edge placed on the surface parallel and transversely to the centerline after rolling is completed. Conditions of Acceptance and Corrective Actions for Cold Recycled Material. Acceptance for payment of the cold recycled material will be determined by visual inspection of the mixture on the roadway. Before proceeding to other work or surfacing treatments, correct deficient cold recycled material to the satisfaction of the Project Manager as follows: Reprocess or repair any area showing an excess or deficiency of asphalt emulsion. Reprocess or repair any area that ravels. If rutting occurs before the surface treatment is placed, re-compact to remove ruts. Reprocess or repair areas not meeting smoothness criteria. Method of Measurement. Work as described will be measured by the square yard of the completed sections for the specified. Asphalt emulsion will be measured by the ton (metric ton). Water used in this operation will not be measured for payment.
