Abstract:

This report describes the research activities of a project dealing with theoretical/numerical modeling and experimental studies of the micromechanical behavior of recycled asphalt material. The theoretical work employed finite element techniques to develop a microstructural model of heterogeneous asphalt materials. The model simulates the load transfer between aggregates using a microframe network scheme whereby the binder-aggregate system is replaced by an equivalent network of finite elements. A nonlinear, softening model was developed through the use of a damage mechanics formulation. Preliminary model results compared favorably with experimental data for indirect tension tests. Experimental work included model verification studies, which investigated idealized cemented particulate systems in order to collect data on particle displacements under load. This data compared favorably with model simulation results. Indirect tension testing was also conducted for a material with a fix percentage of RAP, and preliminary visualization of IDT sample damage evolution was done. Experimental binder characterization studies were conducted on compressive and indirect tension samples. (75 p.)
