Abstract: This dissertation focus on the resistance of runway pavement subjected to blast load. The concept of the multi-layers system was evaluated, and a multi-layers system consisting of Asphalt Concrete (AC) layer reinforced with geogrid (GST), followed by HSC (High Strength Concrete) layer and then ECC (Engineered Cementitious Composites) layer was proposed. A series of large scale laboratory impact tests were carried out, and concluded that this proposed system had better impact resistant than conventional pavement systems. Instrumented field blast tests was conducted to investigate the actual behavior of the proposed system under blast load in the field condition. 3D numerical modeling for the proposed system was developed, and validated based on the results from the field test. It was found the interface strength between layers, and proper material model, and Dynamic Increase Factor (DIF) were critical in controlling the damage pattern. Parametric study was conducted. Finally, a design chart for the proposed multi-layers pavement system under different explosive charge was developed.
