Pavement Management

Pavement management is the process of planning the maintenance and repair of a roadway network or other paved infrastructure to improve road conditions throughout the network. It is also used on runways and airports. Every highway superintendent undertakes walkway management. Traffic management includes the cost of living cycles in a systematic way of repairing minor and major roads and reconstruction projects. The needs of the entire network and budget estimates are considered before the projects are undertaken, as the cost of data collection can change significantly. Pavement management incorporates many of the features and functions required to maintain the quality of the paved material as well as to ensure that the entire road network can sustain itself at the required levels. Although pedestrian management involves the life cycle of commuting from planning to maintenance of any transport infrastructure, road asset management, and road maintenance planning is primarily aimed at road infrastructure.

A high performance racing plane is to have an aileron control rod made out of unidirectional carbon fibre tubing with the following material properties: elastic modulus E = 90 GPa and compressive failure stress OF,comp= 600 MPa. In order to avoid parts of the internal wing structure the control rod is required to have a bend at the tip as shown in the figure. The rod is L = 400 mm long with an inner diameter of 8 mm and an outer diameter of 10 mm. The length of the bent portion of the rod is = 40 mm . The servo applies a maximum compressive or tensile force of F= 200 N on one end of the control rod as shown in the diagram.
