This paper recounts briefly to establish highway control network method, aiming to projection length deformation being bigger in Xinzhou highway survey, puts forward the method of horizontal coordinate system of option zone of central meridian being 11430.

In the thesis, based on the characteristics of highway control network, related promblems about how to make use of GPS to establish the control network of highway construction have been discussed.

Based on the present systematic analysis of basic principle of quality control of highway engineering, this paper studies the management of quality of high-grade engineering projects in SiChuan Provice by the principles of statistics and approaches its adapatable and improvable parts and put forward measures and methods strengthening quality control of highway engineering at present.
