501 GENERAL REQUIREMENTS FOR BITUMINOUS PAVEMENT LAYERS

Bituminous pavement courses shall be made using the materials described in the

Specifications.

The use of machinery and equipment mentioned in various Clauses of these Specifications is

mandatory. Details of the machinery and equipment are available in the Manual for Construction

and Supervision of Bituminous Works. The equipment mandatory for any particular project

shall be in accordance with the Contract Specifications for that project.

501.2 Materials

The binder shall be an appropriate type of bituminous material complying with the relevant

Indian Standard, as defined in the appropriate Clauses of these Specifications, or as

otherwise specified herein. The choice of binder shall be stipulated in the Contract or by

the Engineer. Where viscosity grades of bitumen are specified, they are referred to by a

designation in accordance with IS:73. Where modified bitumen is specified, it shall conform to

the requirements of IRC:SP:53 and IS:15462; and the following provision of this Specification

i) Modified bitumen from refinery sources or blended at approved central

plant or at site using appropriate industrial process and plant with high

shear mill, and testing facilities to achieve stable and homogenous mix

shall be used. The use of high shear mixer or any other device capable

of producing a homogeneous blend is essential when the modifier is in

ii) Transportation tanks and storage tanks shall be insulated and equipped

with effective heating system and circulation/ agitating device to maintain

the specified temperature, homogeneity and viscosity of the bitumen

during transit and storage.

iii) Separation, difference in softening point (R&B), shall not be more than

3ºC for any type of specified modified bitumen when tested as per

Annex B of IS:15462.

Selection criteria for viscosity grade bitumen, based on highest and lowest daily mean

temperatures at a particular site, are given in Table 500-1.

Selection criteria for modified bitumen shall be in accordance with IRC:SP:53.

-10ºCor lower VG-10 VG-10 VG-20

Both the highest daily mean air temperature and the lowest daily mean air temperatures

mentioned in Tables 500-5 and 500-6 can be obtained for the weather station nearest to

the project site from the Indian Meteorological Organization (IMO). This daily mean high

temperature on a specific day is the same as daily “normal” high temperature for that

day as usually reported in some newspapers. The highest of the 365 daily mean high air

temperatures (which usually occurs on some day in May or June) is used in Tables 500-5 and

500-6. Likewise, the lowest daily mean air temperature (which usually occurs on some day in

January) can also be obtained from the IMO. Since these are mean temperatures based on

the average of 30-40 years data, these temperatures are significantly lower than the absolute

maximum temperatures, which may have occurred in a specific year.

501.2.2 Coarse Aggregates

The coarse aggregates shall consist of crushed rock, crushed gravel or other hard material

retained on the 2.36 mm sieve. They shall be clean, hard, durable, of cubical shape, free from

dust and soft or friable matter, organic or other deleterious matter. Where the Contractor’s

selected source of aggregates has poor affinity for bitumen, the Contractor shall demonstrate

through test results that with the use of anti-stripping agents, the stripping value is improved

to satisfy the specification requirements. The Engineer may approve such a source and, as

a condition for the approval of that source, the bitumen shall be treated with approved

antistrippingagents, as per the manufacturer’s recommendations, at the cost of the Contractor.

Where crushed gravel is proposed for use as aggregate not less than 90 percent by weight

of the crushed material retained on the 4.75 mm sieve shall have at least two fractured

faces, except that in the case of bituminous concrete the requirement in this regard shall be

The aggregates shall satisfy the physical requirements set forth in the individual relevant

clause for the material.

501.2.3 Fine Aggregates

Fine aggregates shall consist of crushed or naturally occurring material, or a combination of

the two, passing 2.36 mm sieve and retained on the 75 micron sieve. They shall be cleanhard,

durable, dry and free from dust, and soft or friable matter, organic or other deleterious

matter. Natural sand shall not be allowed in binder and wearing courses. However, natural

sand upto 50 percent of the fine aggregates may be allowed in base courses. Fine aggregates

shall have a sand equivalent value of not less than 50 when tested in accordance with the

requirement of IS:2720 (Part 37). The plasticity index of the fraction passing 0.425 mm shall

not exceed 4 when tested in accordance with IS:2720 (Part 5). The fine aggregates shall

satisfy the physical requirements set forth in the individual relevant-clause for the material in

501.2.4 Sources of Material

The sources of materials proposed to be used by the Contractor shall be tested to the

satisfaction of the Engineer who shall give the necessary approval. The Engineer may from

time to time withdraw approval of a specific source, or attach conditions to the existing

approval. Any change in aggregate source for bituminous mixes shall require a new mix

design, and laying trials, where the mix is based on a job mix design. Stockpiles from different

sources, approved or otherwise, shall be kept separate, such that there is no contamination

between one material and another. Each source submitted for approval shall contain material

sufficient for at least 5 days’ work.

Pre-mixed bituminous materials shall be prepared in a hot mix plant of adequate capacity and

capable of yielding a mix of proper and uniform quality with thoroughly coated aggregates.

Appropriate mixing temperatures are given in Table 500-2 of these Specifications. the

difference in temperature between the binder and aggregate shall at no time exceed 14ºC. In

order to ensure uniform quality of the mix and better coating of aggregates, the hot mix plant

shall be calibrated from time to time. The essential features of the hot mix plants are given in

Annex A of IRC:27.

Rollingmust be completed before the mat cools to these minimum temperatures

If a continuous type mixing plant is used, the Contractor must demonstrate by laboratory

analysis that the cold feed combined grading is within the grading limits specified for that

bituminous bound material. In the case of a designed job mix, the bitumen and filler content

shall be derived using this combined grading.

501.4 Transporting

Bituminous materials shall be transported in clean insulated and covered vehicles. An asphalt

release agent, such as soap or lime water, may be applied to the interior of the vehicle to

prevent sticking and to facilitate discharge of the material.

501.5.1 Weather and Seasonal Limitations

Laying shall be suspended:

i) In presence of standing water on the surface;

ii) When rain is imminent, and during rains, fog or dust storm;

iii) When the base/binder course is damp;

iv) When the air temperature on the surface on which it is to be laid is less

than 10ºC for mixes with conventional bitumen and is less than 15ºC for

mixes with modified bitumen;

v) When the wind speed at any temperature exceeds the 40 km per hour

501.5.2 Cleaning of Surface

The surface on which the bituminous work is to be laid shall be cleaned of all loose and

extraneous matter by means of a mechanical broom and air jet. The equipment for applying

a high pressure air jet from a compressor to remove dust or loose matter shall be available

full time at the site.

501.5.3 Spreading

Prior to spreading the mix, the base shall be prepared by carrying out the required operations

as per Clause 501.8 depending upon the site conditions. Except in areas where paver cannot

get access, bituminous materials shall be spread, levelled and tamped by an approved

selfpropelledpaving machine equipped with an electronic sensing device. The essential

featuresof the paver finisher shall conform to Annex A of IRC:27. As soon as possible after

arrivalat site, the materials shall be supplied continuously to the paver and laid without delay.

The rate of delivery of material to the paver shall be regulated to enable the paver to operate

continuously. The travel rate of the paver, and its method of operations, shall be adjusted

to ensure an even and uniform flow of bituminous material across the screed, free from

dragging, tearing and segregation of the material. In areas with restricted space (such as

confined space, foot ways, of irregular shape and varying thickness, approaches to expansion

joints, etc.) where paver cannot be used, the material shall be spread, raked and levelled with

suitable hand tools by trained staff.

The minimum thickness of material laid in each paver pass shall be in accordance with

the minimum values given in the relevant parts of these Specifications. When laying binder

course or wearing course approaching an expansion joint of a structure, machine laying

shall stop 300 mm short of the joint. The remainder of the pavement up to the joint, and the

corresponding area beyond it, shall be laid by hand, and the joint or joint cavity shall be kept

clear of surfacing material.

Bituminous material, with a temperature greater than 145°C, shall not be laid or deposited

on bridge deck water-proofing systems, unless precautions against heat damage have been

approved by the Engineer.

501.5.4 Cleanliness and Overlaying

Bituminous material shall be kept clean and uncontaminated. The only traffic permitted to run

on bituminous material to be overlaid shall be that engaged in laying and compacting the next

course or, where a binder course is to be sealed or surface dressed, that engaged on such

surface treatment. Should any bituminous material become contaminated, the Contractor

shall make it good to the satisfaction of the Engineer, in compliance with Clause 501.8.

Binder course material shall be covered by either the wearing course or surface treatment,

whichever is specified in the Contract.

501.6 Compaction

Bituminous materials shall be laid and compacted in layers, which enable the specified

thickness, surface level, regularity requirements and compaction to be achieved.

Compaction of bituminous materials shall commence as soon as possible after laying.

Compaction shall be substantially completed before the temperature falls below the minimum

rolling temperatures stated in the relevant part of these Specifications. Rolling of the

longitudinal joints shall be done immediately behind the paving operation. After this, rolling

shall commence at the edges and progress towards the center longitudinally except that on

super-elevated and unidirectionally cambered portions, it shall progress from the lower to the

upper edge parallel to the center line of the pavement. Rolling shall continue until all roller

marks have been removed from the surface. All deficiencies in the surface after laying shall be

made good by the attendants behind the paver, before initial rolling is commenced. The

initial or breakdown rolling shall be done with 8–10 tonne static weight smooth-wheel rollers.

The intermediate rolling shall be done with 8–10 tonne static weight or vibratory roller or with

a pneumatic tyre roller of 12 to 15 tonne weight, with a tyre pressure of at least 0.56 MPa.

The Contractor shall demonstrate the efficiency of the equipment proposed to be used by

carrying compaction trials. The procedure for site trials shall be submitted to the Engineer

for approval. The finish rolling shall be done with 6 to 8 tonne smooth wheel tandem rollers.

Rolling shall continue until the specified compaction is achieved.

Where compaction is to be determined by density of cores, the requirements to prove the

performance of rollers shall apply in order to demonstrate that the specified density can be

achieved. In such cases the Contractor shall specify the plant, and the method by which he

intends to achieve the specified level of compaction and finish at temperatures above the

minimum specified rolling temperature. Laying trials shall then demonstrate the acceptability

of the plant and method used.

Bituminous materials shall be rolled in a longitudinal direction, with the driven rolls nearest

the paver. The roller shall first compact material adjacent to joints and then work from the

lower to the upper side of the layer, overlapping on successive passes by at least one-third of

the width of the rear roll or, in the case of a pneumatic-tyred roller, at least the nominal width

In portions with super-elevated and unidirectional camber, after the edge has been rolled, the

roller shall progress from the lower to the upper edge.

Rollers should move at a speed of not more than 5 km per hour. The roller shall not be

to stand on pavement which has not been fully compacted, and necessary precautions shall

be taken to prevent dropping of oil, grease, petrol/ diesel or other foreign matter on the

pavement either when the rollers are operating or standing. The wheels of roller machine

shall be in good working order, to prevent the mix from adhering to the wheels. Only sufficient

moisture to prevent adhesion between the wheels of rollers and the mix should be used.

Surplus water shall not be allowed to stand on the partially compacted pavement.

501.7.1 Where joints are made, the material shall be fully compacted and the joint

made flush in one of the following ways:

a) All joints shall be cut vertical to the full thickness of the previously laid

mix. All loosened material shall be discarded and the vertical face

coated with a suitable viscosity grade hot bitumen, or cold applied

emulsified bitumen. While spreading the material along the joint the

material spread shall overlap 25 mm to 50 mm on the previously laid

mix beyond the vertical face of the joint. The thickness of the loose

overlap material should be approximately a quarter more than the final

compacted thickness. The overlapped mix shall be dragged back to the

hot lane so that the roller can press the small excess into the hot side

of the joint to obtain a high joint density.

b) By using two or more pavers operating in echelon, where this is

practicable and in sufficient proximity for adjacent widths to be fully

compacted by continuous rolling.

501.7.2 All longitudinal joints shall be offset at least 300 mm from parallel joints in the

layer beneath or as directed, and in a layout approved by the Engineer. Joints in the wearing

course shall coincide with either the lane edge or the lane marking, whichever is appropriate.

Longitudinal joints shall not be situated in wheel track zones.

501.7.3 For transverse joints method a) above shall apply. Transverse joints in the

successive and adjoining layers shall have a minimum offset of 2 m.
