PAVEMENT: Classification----contd.
{"Image DocumentName": "PAVEMENT: Classification----contd.", "Image ImageDescription": "Rigid pavements are those which are surfaced (i.e., paved) with Portland cement concrete. Portland cement concrete possess a substantially higher stiffness (EI) than asphalt concrete due to higher modulus of elasticity of Portland cement concrete as compared to asphalt concrete. Due to high stiffness of Portland cement concrete the total structure of a rigid pavement bends or deflects very little under traffic loads. This is the logic behind calling such a pavement as rigid pavement . Rigid pavements act as flexural members and distribute the wheel load fairly uniformly over the area under the pavement slab, as shown below: Rigid pavements comprise only 7 percent of U.S. paved roads. Load distribution under a rigid pavement.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
