3. INTRODUCTION Development of a country depends on the connectivity of various place with adequate road network. Roads constitute the most important made of communication in areas where railways have not developed much. India has one of the largest roads network in world ( over 3 million km at present). For the purpose of management and administration , road in India are divided into the following categories : National Highways (NH) State Highways (SH) Major District Roads (MDR) Other District Roads (ODR) Village roads (VR)

5. Road Roads are defined as routes or path begin at one destination and lead to another. Road is an open , generally public way for the passage of vehicles, people, and animals.

6. Earth work The sub – grade soil is prepared by bringing it to desire grad. Soil filing Spreading and Levelling compaction

7. PAVEMENTS Pavement is finished with a hard smooth surface. It helped make them durable and able to withstand traffic and environment. They have a life span between 20-30year. Types of pavement Flexible pavement Rigid pavement

8. Flexible pavement Flexible pavements are those which are surface with bituminous or asphalt materials. it’s flexible since the total pavement structure bends or deflects due to the traffic loads. Generally this type of pavement requires some sort of maintenance or restoration every 10 to 15 years.

9. Rigid pavement A rigid pavement structure is composed of a hydraulic cement concrete surface course and concealed base and sub base courses. The surface course is the rigid layer and provides the majority of strength.

10. Types of roads Earth road and gavel road Water bound macadam (WBM)

11. Bituminous road Cement concrete road

12. ROADWAY CONSTRUCTION Carriageway Pavement

13. Kerb A line of stone or concrete forming an edge between a pavement and a roadway, so that the pavement is some 15 cm above the level of the road. Shoulder It is the side of the road. Sometimes it is paved. Sometimes it is gravel. Sometimes it is dirt or grass.
