This is the role of the Pavement Engineer and involves determining the loading on the road to be carried forward to the Pavement Design. The role of the pavement engineer is to provide an adequate thickness of pavement to carry the expected loads without deterioration of the network during the design life. The estimated or projected magnitude and occurrence of

In the geometric design of motorways, railways, pipelines, etc., the design and setting out of curves is an important aspect of the engineer’s work. The initial design is usually based on a series of straight sections whose positions are defined largely by the topography of the area. The intersections of pairs of straights are then connected by horizontal curves.

Includes collecting, transporting, and disposing of surface/subsurface water originating on or near the highway right of way or flowing in streams crossing bordering that right of way. Drainage of highway is important because water damage highway structure in many ways. The water which are dangerous for highways are: Rainwater: Cause erosion on surface or may

In triangulation the base line is of prime importance because it is the only horizontal distance to be measured. It should be measured very accurately since the accuracy of the computed sides of triangulation system depends on it.

Correction for sag is the deference in length between the are and its chord i.e b/t the curved length of the laps and the distance between the supports. It’s us required only when the tape is suspended during measurement.
