1. The document discusses the process of cement road construction including preparation of the subgrade and base, forming, mixing and placing concrete, compaction, finishing, curing, adding joints and edging, and opening the road to traffic. 2. Key steps include preparation of the subgrade and granular base, using formwork to contain the wet concrete, mixing cement, sand, aggregate and water, compacting the concrete, curing it for 14-28 days, and filling joints before opening the cured road to traffic after a month. 3. Proper preparation of the subgrade and base, compaction and curing of the concrete are essential to produce a durable and strong cement road.

2. Using mix Concrete, there Some
Point to Construct the road-
• 1. preparation of Subgrade
• 2. Preparation of base
• 3. Watering of base
4. Formwork
• 5. Joints
• 6. Material mix & placing
• 7. Compaction

3. 8. Finishing of Surface
9. Curing
• 10. Joint filling & Edging
• 11. Open to traffic

4. 1.Preparation of Subgrade
• 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
slope.
• When concrete direct laid on subgrade, For
preventing the water-seepaging into the soil ,
used water proof paper on entire length.

6. 2.Preparation of Base
W.B.M. base :-
As base material of W.B.M. Road; stone ballast &
concrete 10-15cm layer are used With Water.
 For bonding between concrete slab & W.B.M.
used 1:2 cement wash on W.B.M.
•

7. 3.Watering of Base
• If base is dry then using the sprinkling process
on it properly after that placing the concrete.

8. 4. Formwork
• Material for formwork:-
• 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.
3. After 24hrs form work displaced next length
of road.

9. 5. Joints
 Where it 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.
Types of joints:-
• 1. Logitudinal Joints
• 2. Transverse Joints

10. 6. Material Mix & Placing
• Mixer is equipment that mix the concrete
using cement, concrete, sand and water.

11. 7. Compaction
• 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

12. 8. Finishing of Surface
For levelling the surface use floating,
screeding , power trowel. So that there is no
acceptable more than 3mm variation in
concrete level surface.

13. 9. Curing
• Curing is the name of increasing the hydration
process of cement. After setting the concrete ,
curing process done till 14-28days.
• Some method of curing are:-
• 1. Covering with gunny bags
• 2. Sprinkling of water
• 3.By ponding
• 4. Membrane curing
• 5. Steam curing

15. 10. Filling Joint & Edging
 After drying road, clean the joints and fill the
shelling compound or hot bitumen .
 Also bitumen fill road bank.
To protect damaging the sides of concrete
pavements used over burnt brick work.
 In place of brick, provided kerb of pre mix
concrete.

16. 11. Open to Traffic
Generally after a month, road should be open
to traffic.
 If used rapid hardening cement it take 7 days
to open traffic.
