2. Introduction
A hard smooth surface or layer that forms a road
carriageway, airfield runway, vehicle park or other
paved areas.

3. Types of Pavement
Flexible Pavement Rigid Pavement

4. Flexible Pavement Design

5. Wheel Load Transfer

6. Flexible Pavement Construction
Base and Subgrade Preparation
Pavement Surface Preparation
Placement
Compaction

7. Testing
Bitumen Testing
Aggregate Testing
Soil Testing

8. Aggregate Test
Aggregate Impact Value
Aggregate Abrasion Value
Aggregate Crushing Value

9. Aggregate Impact Value
- Passing through 12.5mm IS Sieve
– 100%
- Retention on 10mm IS Sieve –
100%
The sample should be oven-dried
for 4hrs
Aggregate impact value = (B/A) x
100%

10. Aggregate Abrasion Value
Aggregate abrasion value
= (A-B)/B x 100%.

11. Soil Test
Determine The Maximum Dry Density And The
Optimum Moisture Content Of Soil
Determining Water Content In Soil - Oven Drying
Method
Determine The Specific Gravity Of Soil

12. Determining Water Content In Soil
Oven Drying Method
W1=container weight
W2=wet soil specimen in the container
W3=container with the dry soil sample
The water content
w = [W2-W3] / [W3 -W1]*100%

13. Bitumen Test
Determining the Ductility Of Bitumen
Determining Penetration of Bitumen
Determining Flash And Fire Point Of Bitumen

14. Determining the Ductility Of
Bitumen

15. Type of Flexible Pavement
Bitumen Polymer Modified Bitumen

17. Difference Between Flexible and
Rigid Pavement
Flexible pavement Rigid Pavement
 Load is transfer by grain to grain.
 Low strength.
 Low life Span.
 High maintenance cost.
 Rolling of surface is needed.
 Damaged by oils and certain
chemicals.
 Load transfer is not exists.
 High strength.
 Life span is more.
 Low Maintenance cost.
 Rolling of surface is not needed.
 No damage by oils and greases.

18. Advantage
Flexible Rigid
Repair of flexible
pavement is easy.
Additional thickness
added any time.
The flexible pavement
is smooth.
Tolerates a great range
of temperature.
Durability of rigid
pavement is good.
Life cycle of rigid
pavement is long.
Withstand repeated
flooding and surface
water.

19. Disadvantages
Flexible Rigid
Loses some flexibility
and cohesion with time.
Needs resurfacing sooner
then PC concrete.
Not normally chosen
where water is expected.
The life of flexible
pavement is short.
The maintenance cost is
high
May lose skid surface
with time.
May fault at transverse
joints.
