3. Introduction
HIGHWAY is a term commanly used to refer
a major roads intended for travel by the public
between important distinations, such a cities.
A hard smooth surface or layer that forms a
road carriageway, airfield runway, vehicle park
or other paved areas.

Where-
E=rate of super elevation
F=friction factor
V=speed of vehicle (m/s)
R=radios of curve (m)

12. Surface type Heavy rain Light rain
Concrete/Bituminous 2 % 1.7 %
Gravel/WBM 3 % 2.5 %
Earthen 4 % 3.0 %

17.  Low or mountable kerbs:
 Height of 10 cm above the pavement edge.
 With a slope which allows the vehicle to climb over easily
 Semi-barrier type kerbs
 Height is 15 cm above the pavement edge.
 parking vehicles, but at emergency only.
 Barrier type kerbs.
 Height of 20 cm above the pavement edge
 With a steep slope.
 Submerged kerb.
 Provide lateral stability

34.  Base and Subgrade Preparation
 Pavement surface preparation
 Mix trasport
 Placement
 Compaction

35.  Preparation of sub grade could include site
clearence , grading, and composition process.

36.  Laying of boulder.
 Size of boulder 45 – 90 mm (according to IRC-
37-2001).
 Thickness of sub base 150 mm ( according to
design).

37.  Laying of boulder.
 Size of boulder 20-50 mm ( according to IRC-
37-2001).
 Thickness of sub base 175 mm ( according to
design).
 Compaction.
 Sprinklimg of water.

38.  Sprinking of Binding meterial ( bitumen).
 Laying the bituminous concrete mix meterial
at 170 to 190*C.
 Aggregate size 0 to 20 mm.
 Rolling of surfacing.

39. FLEXIBLE PAVEMENT RIGID PAVEMENT
1. Load is transfer by grain to
grain.
2. Low strength.
3. Low life Span.
4. High maintenance cost.
5. Rolling of surface is needed.
6. Damaged by oils and certain
Chemicals.
1. Load transfer is not exists.
2. High strength.
3. Life span is more.
4. Low Maintenance cost.
5. Rolling of surface is not
needed.
6. No damage by oils and
greases.

40. 1. Easily repair.
2. Additional thickness added any time.
3. Smooth.
4. Tolerates a great range of temperature.

41.  Loses some flexibility and cohesion with time.
 Needs resurfacing sooner then PC concrete.
 Not normally chosen where water is expected.
