According to the on-site construction manager, the whitening black construction first introduced the shot blasting process, followed by the rubber asphalt stress absorbing layer. Due to the tight schedule, it is necessary to process 80,000 square meters in 10 days, using a 2-20DT shot blasting equipment from Qirui Tektronix with corner construction, and a 2-4800DH driving device with a daily processing capacity of 12,000 square meters. After shot blasting, the pavement forms a uniform rough and clean surface, which provides a good level for the adhesion of the rubber asphalt gravel stress film and the old pavement.
