This proposed research project for the study of structural flexibility and stronger financial floor kreng in phayao. With the objective of making this project to study, research, and standards relating to the design of the road. Study on design of floor structure, appropriate to the amount of traffic that has occurred within the University. As the skin via a flexible design approach-oriented experience (Empirical design) how the Asphalt Institute (1970) and analytical design methods (Analytical design) how strong analytical and surface of the Portland Cement Association kreng method (PCA) and the 1993 AASHTO method, which has the value soil country through CBR.5% elastic way floor structure by a 10-year rate of increase in traffic, 2% 4% 6% 8% 10% and a floor structure with stronger kreng lifetime 20-year rate increase of 5% of traffic volume in addition to the research project can be considered as part of road construction in University phayao.
