includes rain water gutter to

discharge rain water in monsoon period to the gutter constructed below.

Many cases client provides us complete structural design of the proposed

toll plaza and we fabricate and erect the same as per the designer’s

guidelines. In some cases clients provides us only architectural drawings

of the canopy and our designing team design the structural aspect and

then it is given to our execution team for the work after due approval from

the clients consultants. In some cases the architectural designing and

structural design is done by us based on clients requirements. We have our

tie up with architects who are experts in designing the canopy structure as

ROAD MARKING

Road marking

Road marking is very essential and found useful to channelize the

traffic. It also helps to warn the driver about the changes in

approaching road, junctions etc and thereby helps in avoiding the

accidents.

As per M.O.R.T.H. guidelines all the important roads like National

Highways and expressways should be marked with retro-reflective

paint which will give night visibility. This is achieved using

thermoplastic paint. As the name suggest, it is a temperature sensitive

paint and applied at certain temperature.

Paint

The paint is mainly made up of hydrocarbon resin, pigment for

colorization and glass spears for night visibility. The percentage of each

ingredient is governed by the MORTH Cl. No 803.3. We are

manufacturing the same quality paints (BRIGHTLINE).

Roll of drop on glass beads in road marking

This paint comes in powder form and melted on site in (kettles)

premelters at controlled temperature. This molten thermoplastic paint

is then transferred to marking machine for required marking on road.

While laying the paint on road , glass beads being heavier ,it settles

down in the paint and a thin layer of pigment and other ingredients

covers these glass beads .This results in no reflection when paint is

freshly laid.

To overcome this problem and to achieve immediate reflectivity from

day one of application, certain amount of glass beads are sprinkled on

hot paint. After some duration ( 15 to 20 days of application)these half

embedded ,sprinkled glass beads along with the skin of the paint

applied worn out by moving tires of vehicles and the added glass

17

beads gets exposed and starts reflecting. This reflection then lasts till

the life of the paint applied.

Methods of application adopted in India.

There are three methods generally used world wide

1. Screed box laying

2. Extrusion laying

3. Spray method

In India we use only first two methods to mark the roads with

thermoplastic paint.

Screed box laying: In this method molten thermoplastic paint is laid

through the opening of the screed box and width is restricted

between two carbide strips attached beneath the screed box. Here

flow of thermoplastic paint is under gravity and hence can be layed

at fixed speed depending upon the density and flow properties of

the paint.

In this method thickness of paint varies if the speed of laying varies

resulting in cracking of marking after some time. The lines marked

do not have sharp edges. Generally this method is useful for small

works and detail work like marking junction’s arrows, etc.

Extrusion method: In this type molten thermoplastic is extruded

through an opening (slit) using external force and ribbon of desired

thickness and width is formed near the opening. This ribbon when

comes in contact with the road surface stick up to it .The ribbon

formation is done at about 4 to 5 inches above the ground and is not

speed dependant hence uniform thickness with well defined sharp

edges marking is achieved. This is very fast method of application

and found very useful on new works.

We Vinayaka Structural Engineers Pvt. Ltd. are involved in

thermoplastic road marking since year 2001. Initially company

imported one semiautomatic self driven machine from TRANTEX USA

and seeing the difference in quality and output over hand push

traditional machines, imported fully automatic machine from BORUM

18

Industry A/S Denmark. This advance machine has proved us in many

projects and because of this machine it is become mandatory in all

NHAI project to use fully automatic machine for road marking.

Company has carried out projects in various parts of India. Recently

company has also completed one project in Nepal.

We have our own paint manufacturing facility at MIDC, Mahad, Dist.

Raigad, Maharashtra. Here we have installed fully automatic mixing

plant enabling us strict quality control and uniformity in production.

Present capacity of the plant is 25 MT /day which may be increased to

45 MT if required.

METHODOLOGY FOR APPLICATION OF

HOT APPLIED PAVEMENT MARKING

1.) PREPARATION OF MATERIAL: -

First material in 25 Kg packing from same batch nos. are separated from

the lot and loaded in the truck on which premelters are kept.

Premelters, which are indirect heating type thermoplastic controlled are

of capacity 1000kgs. Each is preheated to 60 degree and then one of the

Preheater is partially loaded. After heating, once the oil has reached a

temperature of 120 degree hydraulic agitation is started. Then

premelter is loaded to its full capacity that is 1000 kgs and heated to 240

degrees (heating oil temperature and 200 degrees material temp.) Now

second premelter is preheated to 60 degrees and partially filled with

material and same method is adopted to heat the material. The oil temp

and material temp. is maintained with the help of the thermostat, which

gives automatic cutoff for heating. This prevents the material from

overheating. This procedure initial load takes 45 min to 60 min. There

after for each next load premelter is filled with fresh material without

stopping agitation and to the quantity, which has taken out from the

premelter for marking. For every load after the first load 20 min. of time

required. Hence twin premelters, which are heated simultaneously, will

provide continuous supply of material/paint to the marking machine.

19

2.) PREMARKING: -

Premarking is done with the help of linedori by connecting the specific

points previously marked. This premarked line is then, followed by the

help of the guider attached to the machine and thermoplastic is laid in

required line and pattern.

3.) APPLICATION: -

Our machine is extrusion type and has a material capacity of 500kgs.

This machine has indirect heating facility for maintaining material

temperature. This material tank is preheated to 200 degree and only

then material is taken from premelter. Temperature in the material tank

is maintained by thermostat.

We undertake thermoplastic road marking as per the guidelines of

MOST and IRC 35.

We undertake mastic asphalt work of any size and various thicknesses.

We have infrastructure to carry out mastic asphalt with conventional

method as well as using advance machinery like automatic batch mix

plant, transit mixers to carry ready mastic mix in hot condition to site, fully

automatic variable width mastic paver finisher etc.

Conventional method:

Mastic asphalt is prepared in small capacity cookers (1MT to 1.5 MT

capacities).Feeding of metal, sand, calcite, bitumen etc. is done manually

with the help of pre-measured containers. This mix is cooked for 1.5 to 2

hrs in mechanically agitated cooker and then the ready mastic is

transported to laying site in small hand trolleys. This mastic so transported

is then floated manually with wooden floats in a width of 1mts to 1.5 Mts.

Laying `requirement.

We have 5 such cookers and sufficient skilled manpower to achieve a daily

output of about 600 Sqm of 40mm thickness laying.

Using advance machinery:

In year 2007 for our work of providing and laying mastic asphalt on

Eastern Expressway (client MMRDA, Mumbai) we have imported mastic

paver finisher and allied machinery from Europe.

This machinery is found to be very useful for large or medium size work

of mastic asphalt. The complete set of machinery consists of following

items.

Transit Mixers

These transit mixers are designed

for 10 MT mastic load carrying

capacity.These mixers are

manufactured at our Ahemadnager

.Here a cylindrical tank made of

special alloy is mounted on chassis

with tilting arrangement.

TOLL PLAZA MASTIC ASPHALT

TRANSIT MIXERS FOR MASTIC

24

Temperature of mastic is maintained in this cylindrical tank with oil

jacketed heating. Mastic is agitated with hydraulic agitator while moving

at very low rpm

Batch mix plant for mastic asphalt: This plant is manufactured here in

India using indigenous design and

spare parts available in local

market.

Plant is designed in such manner

that exact percentages of

ingredients are gathered in hot

condition in the temperature

maintained mixers and also to

ensure continue supply of mastic

to transit mixers.

Here two mixers having heating arrangement is fed alternately by a hoper

fitted with load cell to weigh the preheated dry mix Metal and sand etc.are

heated in specially designed dryer drum to temp.250 degree C and by

using insulated bucket conveyer fed to feeder hopper. Lime powder

(calcite) is separately fed to feeder hopper through calibrated screw

conveyer. This calcite is heated in calcite tank fitted at the starting of screw

conveyer. Bitumen is separately fed through jacketed pipeline and pump to a

reservoir of defined volume (as per the design mix) and from there

pumped to mixers. Achieved output of 120 MT in eight hrs.

Paver finisher:

This paver finisher is imported from Europe. This has hydrostatic variable

speed drive and variable laying width adjustment.

Thickness is adjusted by hydraulic cylinder. This cylinder is used to lower

or lift the paver to desired thickness. Calibrated scale is mounted on side of

the paver, where directly once can see the thickness being laid. It has an

adjustment to maintain the camber of the road. Thickness can be laid from

20 mm to 50 mm using this paver. Average laying speed is about 5

MASTIC BATCHING PLANT

25

km/Hr.in 5.5 Mts width. Infrared

heaters are provided on side of

the paver to seal the joints with

adjoining layer previously laid.

The ready mastic mix transported

by transit mixer to site is poured

in front of the paver finisher. A

distribution screw is mounted on

front side of the paver to

distribute the mastic to its full

width.

Once the mastic poured is spread to full width of the paver; and is started

to move in forward direction to lay the mastic uniformly and in desired

thickness.

Mastic when freshly laid is very

smooth in texture; hence antiskid

is required to avoid skidding of

vehicles.

Antiskid is carried out by

spreading metal size 8mm to 10

mm at the rate of 10 to 12 kg per

Sqm. On freshly laid mastic

which is still hot.

Spreading of size metal (chips) is done just behind the paver, manually or

by chip spreader.

A chain-link fence

(also referred to as

wire netting, chain-

wire fence, cyclone

fence or hurricane

fence) is usually

made from

galvanized or

LLDPE –coated steel

wire. The wires run

vertically and are

bent into a zig-zag pattern so that each "zig" hooks with the wire

immediately on one side and each "zag" with the wire immediately on the

other.

Chain link fencing is widely used as Access Prevention Fencing. Road

Fencing Links is used to prevent the unwanted access of animals, peoples

& vehicles in bounded area. This is most economical concept in modern

fencing. Angle iron posts, pipe posts or wooden poles containing chain

link fencing fabric can be easily installed and reinstalled, chain link fencing

fabric is a fencing material made of steel wire. We provide continuous

mesh without knots or ties except in the form of knocking or twisting the

ends of the wires to form the selvage of the fabric.

Applications:

* Highways & Express ways

* Stadiums

* Power stations

* Airports

* Industrial complexes

* Farm houses

* Zoological parks

* Orchards/ gardens etc.

* Standard dimensions for GI chain link fencing.

* Height: - 1 mtr- 4 mtr

* Width of frame: - 1- 2.5 mtrs.

R.O.W. FENCING

27

* Mesh: - 1", 1 ½", 2,", 2 ½", 3", 3 ½", 4", 4 ½", 5", 5 ½", 6"

* Nominal wire dia - 2 mm to 5 mm.

Chain link fence is most commonly available galvanized which is silver in

color. We also carry colored chain link fence fabric, framework (posts and

rail), colored fence fittings, gates (swing and slide), and gate hardware for

all fencing applications from standard residential to light commercial, to

heavy commercial and industrial fence applications. Colored fence fittings

and chain link framework (posts and rails) are either powder coated, or

coated in a heavy vinyl coated (PVC) material in standard colors such as

black, dark brown, and dark green. White is also available as special order

fencing. It is not uncommon to combine the two and stretch a vinyl coated

chain link fabric on a galvanized frame. All aluminum chain link fabric,

aluminum tubing, and aluminum chain link fittings and gates are also

available for special applications and is preferred by many near saltwater.

The popularity of chain-link fence is due to its relatively low cost and eases

of installation. A further advantage is that due to the open weave, chain-

link fences are transparent, and do not obscure sunlight from either side of

the fence. If a semi-opaque fence is desired, this can be achieved by the

insertion of slats into the mesh.

Available wire thickness:

We can provide fencing in thickness starting from 1.5mm to 6mm in G.I. /

P.V.C / M.S. / S.S.

Available Mesh sizes:

Starting from half inch to 6 inches, most popular sizes are 25mm, 40mm,

50mm, 55mm, 60mm, 65mm, and 75mm.

Available width:

Starting from 100mm to 4000mm (1ft. to 13ft.)

Available Length:

Normally fencing roll are supplied in 15 and 30 mts. length. We can supply

the roll as per individual requirement

Material: PVC coated iron wire, galvanized iron wire, stainless steel wire.

28

Installation

The installation of chain-link fence involves setting posts into the ground

and attaching the fence to them. The posts may comprise steel tubing,

timber or concrete and may be driven into the ground or set in concrete.

End posts, or terminal posts, must either be set in concrete or anchored to

prevent leaning under the tension of a stretched fence. After the end posts

are set, line posts are driven in equally spaced at intervals of 2.5-3.0m. The

fence is then attached at one end, stretched, and attached at the other; the

excess being easily removed by "unscrewing" a wire. Finally it is tied to the

line posts with aluminum wire.

METAL CRASH BARRIERS (GUARD RAILS):

Presents cold roll forming lines from steel for producing w-beam and Thrie

beam highway crash barriers as per ASTM standards and MORTH

specification. These cold roll forming lines are customized in composition

and could be adopted with respect to one’s specific requirements. The

various options are: a fully automatic line from coil input to final profile of

the required size with punches; w-beam and or tri-beam and or c-channel

for post and spacers can be formed as required; and a roll forming

machine with sheet feeding without punching.

METAL CRASH BARRIERS (GUARD RAILS) is probably something

most of the people don’t think about, that is until it saves their lives. It is a

proven road safety system and is brought to you by Vinayaka Structural
