the proposed SMA mix can be produced, placed, and compacted to meet the requirements of this specification. Place a minimum of 100 tons at a location identified on the approved paving operation QC Plan for each trial demonstration. Simulate the hauli ng time for the demonstration. Obtain and test three loose mixture samples at the plant for asphalt content, gradation, and draindown and three pavement cores from the demonstration pavement for density. Test one set of volumetric specimens for Air Voids at N design
limits for both single and multiple sample tolerances for any parameter, perform another demonstration. If vibratory rolling is proposed, demonstrate to the satisfaction of the Representative that no breaking of aggregate or flushing of asphalt binder results from the vibration. If the contractor requests to waive the requirement for a demonstration strip, and is approved by the Representative, obtain three cores from the first 100 tons of the first day’s production placement as soon as temperature allows extraction. Cores will be used to demonstrate to the satisfaction of the Representative that no breaking of aggregate or flushing of asphalt binder results from the vibration. No payment will be made for the demonstration placement, when waived by the Representative.
1.a Placing. Unless otherwise allowed or indicated, deliver, place, and compact SMA paving mixtures during daylight hours. Ensure the mixture does not contain lumps of cold material. Deliver and place SMA mixtures at the temperatures specified in Table D. Use a material transfer vehicle (MTV) as specified in Section 108.05(c)5 to apply the final surface course. Have the MTV perform additional mixing of the SMA material and then deposit the mixture into the paver at a uniform temperature and cons istency.
1.b Spreading and Finishing. Section 413.3(h)1.b and as follows: Plan and schedule operations to minimize hand work of SMA. Do not allow the finished pavement surface to flush. Flushing is continuous or repeated areas of excessive asphalt on the pavement surface. Areas that are deter mined to be flushed will be considered defective work. 1.c Field Technician. Section 413.3(h)1.d. 1.d Safety Edge. Construct the Safety Edge as the standard edge treatment on the outside edge of asphalt pavements and shoulders. Use the Safety Edge for SMA courses with a depth of 1.5 inches or g
