Paving Operations. Do not raise (dump) the wings of the spray paver receiving ▇▇▇▇▇▇ at any time during the paving operation. The Engineer may waive this requirement if it is determined that raising (dumping) the wings will not produce detrimental segregation. If segregation or irregularities in the pavement surface or density are noted, review the plant, hauling and paving operations and take corrective action. The recommendations made in KDOT’s "Segregation Check Points" should reduce the segregation and irregularities to an acceptable level. Copies of KDOT’s "Segregation Check Points" may be obtained from the KDOT District Office or Field Engineer.
