On a railroad, a -0.8% grade meets a +0.4% grade at Sta. 2 + 700 whose elevation is 30 m. The maximum allowable change in grade per station having a length of 20 m is 0.15 %. It is desired to place a culvert to draw the waters during heavy downpour. Where must this culvert be located? At what elevation must the invert of the culvert be set if the pipe has a diameter of 0.9 m and the backfill is 0.3 m high. Neglect the thickness of the pipe. A. STA. OF INVERT PIPE? B. ELEVATION OF INVERT PIPE?

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.
