Welcome to the COHESIVE research group website. The COHESIVE research group is supervised by Dr. Yong-Rak Kim. We have been working with experimental tests and computational models of crack growth and propagation on different types of bituminous media. Our experimental and simulation laboratories are connected in a way that all the parameters measured in the experimental tests are used to develop and improve our computational models. Using the interconnection between laboratory measurements and numerical models we predict the behavior of asphaltic mixtures and structures. With the combination of basic tools of fundamental mechanics, materials characterizations, problem solving techniques and computer codes development, we use our models to solve real and complex problems such as roadways and bituminous mixtures subjected to different loading conditions. Based on and understanding the fracture mechanics of materials, better estimations of materials responses can be made.
