Highway engineering is an engineering discipline branching from civil engineering that involves the planning, design, construction, operation, and maintenance of roads, bridges, and tunnels to ensure safe and effective transportation of people and goods. Highway engineering became prominent towards the latter half of the 20th Century after World War 2. Standards of highway engineering are continuously being improved. Highway engineers must take into account future traffic flows, design of highway intersections/interchanges, geometric alignment and design, highway pavement materials and design, structural design of pavement thickness, and pavement maintenance.
A district road with a bituminous pavement has a horizontal curve of 1000 m for a design speed of 75 km ph. What is the super-elevation?
What is the minimum value of camber provided for thin bituminous surface hill roads?
Design of horizontal and vertical alignments, super-elevation, sight distance and grades, is worst affected by?
Fill in the blank:
Thickness of a pavement may be reduced considerably by _______.
What is the total length of a valley formed by two gradients - 3% and + 2% curve between the two tangent points to provide a rate of change of centrifugal acceleration 0.6 m/sec2, for a design speed 100 km ph?
