This document summarizes the construction of a 6.5 km private road located in Ranipur, Haridwar, India. It describes the various layers that make up the roadway, including earthwork, granular sub-base, wet mix macadam, bituminous macadam, bituminous concrete, and finishing touches like kerbs and shoulders. The layers are constructed in sequential order, with careful compaction and mixing of aggregates and binders at each stage to support vehicular traffic on the carriageway. Proper camber is built into the road surface to allow for water drainage off the sides of the paved area.

The part of a road used by vehicular
traffic is called carriageway.

11. Sub Base Layer

12. It is a road base material
consisting of crushed rock/slag
usually premixed with controlled
amount of water sufficient for
adequate compaction.

13. BITUMINOUS MACADAM
> Bituminous macadam consists of
aggregate and appropriate binder, mixed in a
hot mix plant and laid with a mechanized
paver.
> It is an open graded mixture suitable
for base course and is laid in a single course
or in multiple layers on a previously prepared
base.

14. FINISHING OF SURFACE(ROLLING)

15. AGGREGATE
COARSE AGGREGATE
The coarse aggregate consists of crushed rock,
crushed gravel or other gravel or other hard
material retained on 2.36mm sieve.
FINE AGGREGATE
Fine Aggregate consist of crushed or naturally occuring
material or their combination passing 2.36 mm sieve and
retained on 75 micron sieve.

SPREADING

17. CAMBER
A slight downward curve from the middle to the
sides of a surface (such as a road)
PERCENTAGE OF CAMBER- 2%
PURPOSE OF CAMBER

18. 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.
KERB

19. SHOULDER
It is the side of the road. Sometimes it is paved.
Sometimes it is gravel. Sometimes it is dirt or grass.
