【 摘 要 】

The low temperature crack propagation resistance of pure and polymer modified mixtures is analysed in the paper by means of linear and nonlinear fracture mechanics. The influence of two bitumen-modification binders is considered: styrene-butadiene-styrene (SBS) and ethylene-vinyl-acetate (EVA). The experiments demonstrated that the fracture toughness values increase, and the maximum vertical strain values decrease, with a decrease in temperature. It was established by both techniques used in the paper that the lowest fracture toughness was obtained using the EVA binder.
