Test: Design of Highway Pavements

The surface of highway pavement should be designed to allow no rolling resistance for safety purposes.

The soil becomes weak in rainy season due to the absorption of water in the soil.

The pavement layer is considered most superior if it distributes the load equally to all parts of pavement.

The cement concrete roads have a greater life than remaining all pavements which may last even up to 100 years.

The structural design like highway speed, geometric design is given the most importance in design.

The surface of the pavement should be sufficient enough to resist the skid of vehicles by using friction.

Roughness and uneven roads will increase the cost of vehicle operation and maintenance of vehicle cost.

The drainage layer is the sub base layer which is used to collect the water from pavement surfaces to send to ground water.

The concrete pavements are designed to sustain a stress of 45Kg/cm2 which is the maximum limit.

The ICPB uses mostly interlocking concrete paver blocks for the construction of pavements.
