1. The document presents information on the construction of cement concrete roads (C.C. Roads), outlining various steps involved like preparation of base, formwork, mixing and placing concrete, compaction, finishing, curing, and joint filling. 2. Key steps discussed include preparation of subgrade, laying waterproof paper, using different base materials like WBM or concrete, mixing concrete using batch or continuous mixers, and placing concrete through alternate bay or continuous bay methods. 3. Finishing involves floating, belting, and brooming, while curing takes 14-28 days through various methods like sprinkling water or using membranes. The road can then be opened to

8. 1. Rolling on sub grade by roller
2. Filling the granular soil in the weak part
and pot holes
3. Correct the soil coat , Camber ,
longitudinal slop
When concrete direct laid on subgrade,
For preventing the water-seepaging into the
soil , used water proof paper on entire
length.

10. Choose any one type of base
1. W.B.M. base
As base material of W.B.M. Road; stone
ballast, concrete 10-15cm layer are used. For
bonding between concrete slab & W.B.M. used
1:2 cement wash on W.B.M.
2. Concrete base
On the road used 10cm Cement
concrete(1:2:4) or lime concrete(16:32:64)
10

11. 3. Granular medium material layer
10-15cm composite layer of sand ,
moorum , bajri are used for better drainage
facilities
4. Stabilization soil
11

12. Material for form work-
Wooden sheets, battens, plywood, fibre hard
board, steel plates, angles, rope, minerals.
1. before using form work, it should free from
all type material like as dust ,cement.
2. To placing the concrete in appropriate
depth used 2.5-5cm thick and 3mtr long
wooden sheeting.
12

13. 3. The depth of wooden block must be
same as level of slab thick.
4. After 24hrs form work displaced next
length of road.
13

14. If base is dry
Than using the sprinkling process on it
properly after that placing the concrete.
14

15. Where is necessary to provide
transverse, Longitudinal joints; there wedge
of woods, metals fix on level of concrete.
After setting of concrete it should be pull
out.
If provided the dowel bar in joints, bars
should be fit at right position.
15

16. Mixer is equipment that mix the concrete using
distinct amount of cement , concrete, sand and
water. Concrete slab should have more than 5-10cm
thick cause of drying.
Used two type mixer-
1. Batch mixer-
at site, used for small road construction
2. Continuous mixer-
Continuous mixer used for large construction .
if distance is more from site , mix concrete
transported at site within setting time.

18. Two methods generally used in placing of
concrete-
1. Alternate bay method-
Placed the concrete on both side of
road alternatively like as1,3,5… part at one
side and 2,4,6… part other side .
1st side
2nd side
This method have slow process due to road
traffic problems.
18

19. 2. Continuous bay method-
construct one side of road regularly, if
completed some part of first side than
construct other side.
this method have fast process without
no obstruction of traffic
19

20. Purpose of compaction is that to pull out
air from void and make concrete harden.
Compaction done by-
1.mechanically surface vibrator
2. manually hand tempers
20

21. 8. Finishing of surface
1.Floating-
For levelling the surface use floating,
scree-ding , power trowel. So that there is
no acceptable more than 3mm variation in
concrete level surface.
2.Belting-
For making surface clean used belting
process. Belt is nothing but a 15-30cm thick
sheets of canvass which have more length
than road.
21

22. 22

23. 3. Brooming-
Brooming is the process in which we
made rough surface parallel to road by
brush.
It useful in avoiding slip & comfortable
travelling on road .
the depth of line on road no more than
1.5mm.
23

24. Curing is the name of increasing the
hydration process of cement.
after setting the concrete , curing
process done till 14-28days.
24

25. Some method of curing are-
1.Shading concrete works
2. Covering with hessian & gunny bags
3. Sprinkling of water
4.By ponding
5. Membrane curing
6. Steam curing

27. 10. Filling joint
After drying road, clean the joints and fill the
shelling compound or hot bitumen .
also bitumen fill road bank.
27

28. To protect damaging the sides of
concrete pavements used over burnt brick
work.
in place of brick, provided kerb of pre mix
concrete.
28

29. Generally after a month, road should be
open to traffic.
If used rapid hardening cement it take 7
days to open traffic.
