Data Analysis of Sield Tunnel Deformation from Real-Time Monitoring with Wire…
As an important part of critical infrastructure, shield tunnel is widely used in urban area of China recent years. The safety of shield tunnel during construction and operation has drawn more and more attention. In the operational period, real time deformation monitoring is an effective way to help us to reveal the long-term deformation mechanism and control the lifetime safety of shield tunn…
Effects of Magnesium Hydroxide on Asphalt Pyrolytic Characteristics and Kinet…
Thermogravimetry experiments and thermal analysis kinetics are used to analyze the effects of magnesium hydroxide on asphalt pyrolysis characteristics. The pyrolysis models are developed based on experiments to evaluate the flame-retarded mechanism of magnesium hydroxide to asphalt. The results indicate that asphalt pyrolysis process in N2 is a single stage, and presents unimodal character in D…

A viscoplastic foam model for prediction of asphalt pavement compaction
Compaction is one of the most important factors affecting the future performance of asphalt pavement. Hot mixture asphalt materials exhibit significant time-dependent response under mechanical and thermal loadings, which can involve elastic, creep and plastic permanent deformation. The irreversible permanent deformation part will generate compaction. Foam-type model has been considered an effic…
Finite Element Modeling of Dynamic Tire/Pavement Interaction
Tire/pavement interaction has been an important research topic in pavement engineering for many years. This paper presents a finite element model for dynamic tire/pavement interaction, which can effectively include the dynamic tire rolling effect to predict the pavement response. The model represents a 4?tire vehicle. The tire is modeled as a finite strain hyperelastic material and pavement str…
