The pavement design given by different bodies like IRC,CHIT, IHE, HRB ,etc.

Here we will follows the IRC method of design which is

 prescribed by MORTH(ministry of road transportation &

highway)

We will use the code IRC-37-1984 and IRC-81-1987 for

the designing of pavement.

There is two Formula of road design

1.empirical method(30 msa).

2.analytical method (150 msa)

(msa=million standard axles)

Design Factor

 Design of wheel. load depends on tyre pressure contact pressure etc.

It also depends on the repetation of load and ESWL

( equivalent single wheel load).

Methods for calculation of design factor:

Group index method ,

CBR method(CHSD),

CBR method(IRC),

CBR method by cumulative standard axle load, California resistance value method,

Macleod method

Analytical method of design. As per irc-37-2001 based on the performance of the

existing design and using analytical approach, simplecharts(fig-7 and fig-2) and a catalogue of pavementdesign (table-1, table-2) has been added for use of ourproject.

Our design is depend upon CBR value range and designtraffic value ranging from 1 msa to 150 msa for anaverage annual temp of 35 degree c.

DESIGN

Design traffic in terms of

cumulative no. Of axle.

CBR value of subgrade.

TRAFFICThe recommended method consider traffic in terms of

cumulative no. of standard axle (8160 kg) to carried by pavement during the design period.

For the estimating design traffic the following information

is needed.1.initial traffic data in terms of no. of commercial vehicle per day(CVPD)

2.traffic growth rate during the design life in %.

3.design life in no. of year.4.vehicle damage factor.

5.distribution of commercial traffic over the carriageway.

Laboratory Test For our project we have done CBR Test as per below

details:-

CBR- CBR test, an empirical test, has been used todetermine the material properties for pavement design.

Empirical tests measure the strength of the material and arenot a true representation of the resilient modulus. It is a

 penetration test wherein a standard piston, having an area of3 in2 (or 50 mm diameter), is used to penetrate the soil ata standard rate of 1.25 mm/minute. The pressure up to a

 penetration of 12.5 mm and it’s ratio to the bearing value of astandard crushed rock is termed as the CBR.

Specification:-

a. CBR apparatus consist mould of

150mm dia width, base and collar

 b. Specimen collected from field.

c. A load is applied by standard plunger

with dia 150 mm @ of 1.25mm/min.

d. Get a curve with a load value onstandard 1370 and 2056kg.

e.  The value is explain in % of actual

load by penetration of 2.5mm and

5mm.

f. C

 

.

g. Two value obtained, we will be

choose larger one.

COMPUTATION OF DESIGN TRAFFIC VOLUME

o The design traffic is considered in terms of cumulative no of standardaxle (in the lane carrying max. load) to be carried out during the designlife of the road.

A=CVPD,  N=cumulative no. of standard axleD=lane distribution factor, F=vehicle damage factor.

n=design life of road, r =annual growth

x= no. of year between the last count &year completion of

construction, P= no. of commercial vehicle as per last count

Cont.. o Generally we consider 7.5% annual growth if adequate

data not available for details we can refers IRC 108.

DESIGN LIFE:

  It is 10 to 20 year.

Vehicle Design Factor:

  The vehicle damage factor is a multiplier to convert theno. of commercial vehicle of different axle load to the no.

of standard axle load repetition.

Vehicle damage factor & liquid development factor

Initial traffic by vol.in term of no of

commercial vehicleper day

150-1500 3.5 1.5

>1500 4.5 2.5

The distribution of commercial traffic over the carriage- way will be based on both direction.It is based on 75% of total no of commercial vehicle.

Pavement Thickness and

Composition:-

For the design of pavements to carry traffic in therange of 1 to 10 msa, the pavement thickness chart isgiven in figure and the traffic in the range is 10-150

Msa, the pavement thickness design chart is given infigure(by IRC 37-2001).

Design of SH-34:- (By using IRC standard).

DATA:

 After traffic volume survey we get the CVPD=194 Design life of SH is=10 year Traffic growth as per IRC=7.5%. Design vehicle design factor=3.5(rolling area).

CBR % data=3.42% approximately=4%DESIGN PART:Distribution factor for two lane single carriageway ofhighway= 0.75%. So 

N= (365*((1+r) n-1))/r (*A*D*F) = (365*((1+0.75)10-1))/0.075*400*0.75*3.5 =2629607.572=2.62 MSA (approximately=3 MSA)

Contd…  Now by using CBR of 4% value can be find thickness

for 3 Msa.  Graph for total thickness=580 mm. 

Then now pavement composition interpolated frograph of CBR 4%. 

 We get the design of pavement thickness from thegraph. 

Bituminous surface= 25 mm SDBC 

Road base: GSB=280 mm. 

 WMM=250 mm. 

BM=50 mm.
