On 14th March, Prof. Lev Khazanovich from University of Minnesota made a presentation in the School of Civil Engineering and Transportation. Prof. Khazanovich has obtained several TRB rewards. He is also the co-editor of International Journal of Pavement Engineering and he has served as a reviewer for ASCE, ASTM. Professor Khazanovich gave a lecture entitled with "Mechanistic-Empirical Design of Concrete Pavements: Past, Present, and Future".

At the meeting, Professor Khazanovich firstly introduced the concrete pavement mechanic analysis theory that Westergaard developed the beginning in the last century, and explained Westergaard equations and models in details. He did a brief description about the evolution of the finite element analysis method .From the 1950s, the United States built several test sections to verify the theories and models. Professor Khazanovich introduced the AASHO test road and made a comprehensive exposition depending on the results of the test roads. The complexity of the pavement material, and application environment made it very difficult to determine the characters of the concrete pavement by a single aspect. Because of the shortcomings of the mechanical analysis and empirical analysis , Professor Khazanovich  presented mechanics - empirical design method which is widely applied in the world. Finally, Professor Khazanovich talked about some of his own unique insights about the future of the pavement design method.

After the meeting, the students discussed with professor Khazanovich on the future trend of pavement design.
