Design Joint Width and Joint Spacing- Expansion Joint

Expansion Joint:

Coefficient of Thermal Expansion, α

= 10*10-6 mm/mm/oC

Spacing of Expansion Joint = 140 m

in 1mm = 10*10-6 mm/oC

in 140000mm = 140 000* 10*10-6 mm/oC


for Temp gradient /oC = 1.4 mm
So for φt = 15oC
1.4 mm *15oC= = 21 mm
Design Joint Width and Joint Spacing- Contraction Joint
Contraction Joint 4.5 m (15 times thickness ~15* 300 mm)

Drying Shrinkage = 0.06%

So for 100 mm = 0.06 mm

For 1 mm = 0.06/100 mm = 0.0006 mm

so in 4.5 m or 4500 mm:

For 4500 mm = 0.0006mm * 4500 = 2.7 mm

cement and water, required for mortar (sieved from
concrete ) to penetration resistance
Find load for 25 mm penetration
3.43 N/mm2 ( 35 kgf/cm2 )
Load in kg/area of plunger

New IS: 1199 Part 7
Joint cutting, open form work, no compaction

1. Initial curing of concrete can be done by


techniques - fogging or using evaporation
reducers, or by providing sunshades,
windscreens.
2. Intermediate curing: Is done when concrete
surface finishing operations has been
carried out before final setting of concrete.

No Joint cutting, No open


form work, placement,
compaction. Initial curing ,
finishing -yes

Preparation of Subgrade
➢Subgrade : Prepared earth surface on which a
pavement is placed or upon which the foundation of a
structure is built.
➢Sub soil: ‘Subsoil’ refers to the stratum of soil immediately
below surface soil or topsoil.
➢ Often this layer is overlooked, as most land management is
focused on topsoil, which can be altered drastically by cultivation
and other practices.
➢ 2-3% Camber in transverse.

➢ 10 m or 10000 mm * 2%= 200 mm


Suitable soil Fill material, -
Compaction

➢ Max dry density min = 1.65-1.75 gm/cm3

➢ Relative Standard compaction, min

➢ 00% standard MDD with 2.5 H. kg in three layer

➢ 97 % modified MDD with 5 kg hammer in 5 layers

➢ Minimum CBR 5% /SPT 5 ton /sq m/bearing capacity, CBR=
