To reduce the stress concentration on the friction between aircraft wheel and road surface and reduce the channel pavement destruction by snow-clean vehicle, to prevent the dust produced in the friction of aircraft wheel and road joints from entering to aircraft engine and to prolong the service life of airport runway, all the exposed kerfs, edges and sharp corners in large airport field road should be chamfered. The study was made on the chamfering diamond saw blade and the chamfering construction technology, which was considerably valuable for domestic airport construction.
