Lecture 2. • Lecture Content…….. • Two layer System (bermister) • Vertical Surface Deflection • Vertical Interface Deflection • Three-layer Theory: • Two-layer Theory (Burmister) • Burmister determine the way to find Stress, Strains, Deflections. • Assumptions • Load were considered as UCLA • Material in each layer is homogenous, isotropic elastic. • Surface layer infinite depth finite (know Z value) • Bottom layer are in continuous contact with each other. • Layer in continuous contact (bonded layer system) • Interface Deflections • • Three-layer Theory: Boussineas Burmister): The two layer theory wasn’t applicable (anymore), Boussineas Burmister develop three layer system to analyze. Stress, strains and deflections. • 00:00 Flexible Pavement Stress Analysis • 00:50 Two layer System (bermister) • 04:13 One layer System • 05:40 Three-layer Theory: • 08:53 Vertical Interface Deflection • 12:46 Vertical Surface Deflection
