Abstract：Aiming at the problem of pavement height adjustment in expressway pavement construction, the method of adjusting the pavement height is put forward by using multi-function curve in combination with the construction case of a certain expressway pavement.Using the level gauge and eight-wheel flatness meter, the road surface cross-section elevation and flatness are detected.The results show that this method can quickly determine the height adjustment of each section, which has the advantages of minimum change of the original design elevation, simple calculation and saving construction cost.The final pass rate of the section is 87%, and the road surface smoothness passing rate 100%.The experiment analysis is also carried out to the triangulation height measurement accuracy of the intermediate observation method.The results show that this method can be used to replace the three or four leveling measurement in highway elevation survey.
