Abstract: Smooth degree is one of the siniifeant indexes of the Pavement quality and sevrise level. Both construction and design are important segments for high quality assuarnce. The Passage also Porbes into the further condition and the afecting factors when eomPleted.Through surveying the up,median and down layer of the aetual Porjcet we analyze the relations among each layer that confomrs to the consturction level at Persent and the reason for unsmooth,and also Put forwrad the controlling measures.
