What are the Components of Road structure?
In this article will study about components of the roads and the structure of the roads and its composition after reading this article you will understand a lot about components of the road structures. We will try to make it as simple it can be.
Carriage Way:
Carriageway is the width of the road on which traffic moves without any restriction.it generally consist of traffic lines and the width of carriageway depend on the lines of traffic. Traffic lines are those lines on which traffic can move freely without any restriction. Each country has its own rules for the width of carriageway for insistence how long should it be in some country for single line road its 2.44m in some its more than that for two line its 3.75m in some more then that.
Formation Width:
The formation width of road is the sum of carriageway, shoulders and separators (if there is any).
Kerb:
Kerb is the boundary line formed from stone or concrete block which separate the carriageway form footpath. There are different types of kerb with different types of height. There are four type of kerb which are low or mountable Krebs, semi-barrier kerb, barrier kerb, and submerged kerb. Iow kerbs are used for traffic to remain in line and also separate the shoulder from the road so the driver can enter the shoulder area with little difficulty its height is 10cm (4inch). A semi barrier kerb has height of 15cm (6inches). Barrier kerbs has a height of 20cm (8 inch). They are provided where pedestrian traffic is in considerable amount. Submerged kerb are used in rural roads the basically provide stability to the road pavement.
