TX Research Engineer Supervised and conducted research projects in the area of pavement engineering and materials.
Current research involves analysis of rheological behavior of asphalt binders during construction.
Factors affecting the viscosity of asphalt binders at high temperatures were determined for 50 asphalt binders. Five TxDOT construction projects were selected for field evaluation. For each construction project, the binders were obtained while construction was in progress and the rheological behaviors of these binders were determined. Provide technical assistance to TxDOT personnel on Superpave related issues. Co-supervised graduate students individual research studies.
