报告简介

Building and maintaining a robust roadway network is crucial to the economic growth as well as national security of a state, yet it demands intensive investment of resource and capital.  In the United States, the roadway condition is deteriorating rapidly, despite the huge spending on pavements. The key to building a more robust pavement system with ever shrinking governmental fund lies in advanced pavement research, which helps reveal the secret of how to invest smartly via advanced modelling, innovative design, intelligent construction, and optimized planning. This talk gives insights on three tropics of Dr. Mu's advanced pavement research. The first topic describes a novel approach proposed to investigate the interface facture of ultra-thin whitetopping under fatigue loading. Laboratory fracture tests in conjunction with cohesive-zone based numerical modelling were first performed to reveal the fracture mechanism at the interface of composite materials. An accelerated loading test was then carried out to quantify the fracture process of real-scale specimens under fatigue loading. An innovative non-destructive approach was also developed to more accurately detect the degree of interface fracture during the accelerated loading test. The second topic introduces the Mechanistic-Empirical pavement design methodology that is the basis of the new-generation AASHTO pavement design guide and its continual model development. The last topic focuses on the optimization of pavement network based on the Remaining Service Interval (RSI) concept and mix-of-fixes rehabilitation strategy.
