DIMENSIONS ND WEIGHTS OF RO DDESIGN VEHICLES

1 INTRODUCTION1.1. The object of framing this Standard is to lay down abasis for designing road components. The dimensions and weightsof . vehicles are cardinal factors in the design of road elements.The width of the design vehicle bas a bearing on the width oftraffic lanes and that of shoulders. The height of the vehicleaffects the clearance to be provided in designing road underbridges, electrical service lines, and other overhead structures.The overall length of the vehicle including trailer and semi-trailercombinations) has to be taken into consideration in designing horizontal curves and vertical curves, as also in framing safety regulations for passingand overtaking. The axle load affects the designof the thickness of pavement, whereas the total weight of the

vehicle governs limiting gradients.1.2. The Ind ian Roads Congress Standard on Dimensionsand Weights . of Road Design Vehicles was first published inJanuary , 1954. When the question of metricization of thisstandard was taken up, it was felt that since by that time considerable changes had taken place in the design and constructionof motor vehicles and concept of geometric and structural designof the highway system both in this country and abroad, t l ~ r wasneed of its wholesale revision. Accordingly, a revised draft for the Standard was preparedby L.R. Kadiyal i. This was modified in the Ministry of Shipping and Transport Roads Wing) considering the. current amendments to the Indian Motor Vehicles Act 1939 an

IRC : 3-19832. SCOPE

2.1. The Standard shall be applied in designing all roadelements except culverts and bridges, the latter being governed bythe IRC Bridge Codes.2.2. For purposes of this Standard three types of commercial vehicles have been recognised :i) Single unit

ii) Semi-traileriii) Truck-trailer combination.

The selection of the vehicle type for design of a road .woulddepend upon terrain conditions, economic justification, importanceof the road and similar other considerations.. As a general guide, roads in steep and mountainous terrainneed not be designed for truck-trailer combination and may only bedesigned for single unit vehicle and where economically feasible,for semi-trailers.

Subject to the above, such of the maximum dimensions andweights out of those specified here shall be used that have theseverest effect in the design of any road component. All road.components, to be newly built or improved, shall be so designedthat they are i n ~ t i l l y adeq:uate or capable of being made adequatesubsequently when the necessity arises, for the movement of vehicles couforming to this Standard and selected for design of theroad. 3. DEFINITIONS

3.1. AxleThe common axis of rotation of one or more wheels, whetherpower driven or freely rotating, and whether in one or more segments, and regardless of the number of wheels carried thereon.3.2. Axle GroupAn.assemblage of two or more consecutive axles consideredtogether in determining their combined load effect on a pavementstructure.3.3. Gross WeightThe weight of a vehicle and/or vehicle. combination without load plu s the weight of any load thereon

fI

IRC: 3-19833.4. Length, OveraUThe total longitudinal dimension of any vehicle or combination of vehicles, including any load or load-holding devicesthereon.3.5. Height, OverallThe total vertical dimension of any vehicle above the groundsurface including any load and load holding device thereon.3.6. Semi-TrailerA vehicle designed for carrying persons or property anddrawn by a t r u c k ~ tractor on which part of its weight and load rests.3.7. Single Axle An assembly of two or more wheels whose centres are in onetransverse vertical plane or may be included between two paralleltransverse .vertical planes one metre apart extending across the fullwidth of the vehicles.3.8. Tandem AxleAny two or more consecutive axles whose centres are morethan 1.2 m but not more than 2.5 m apart and are individuallyattached to andjor articulated from a common attachment to thevehicle including a . connecting mechanism to equalise the loadbetween axles.3.9. Tandem Axle WeightThe total weight transmitted to the road by two or moreconsecutive axles whose centres may be included between paralleltransverse vertical planes spaced not less than 1.2 m but not morethan 2.5 m apart extending the full width of the vehicle.3 I0. TrailerA vehicle designed for carrying persons or goods and drawnby a motor vehicle which carries no part of the weight and load ofthe trailer on its own wheels.3.11. TruckA motor vehicle designed, used, or maintained primarily forthe transportation of goods.

IRG: 3-19833.12. Truck-TractorA motor vehicle designed for drawing other vehicles, but notfor a load other than part of the weight of the vehicle and loaddrawn. 3.13. Truck- Trailer CombinationA truck or a tractive unit with a trailer.3.14. Width OverallThe total outside transverse dimension of a vehicle includingany load or load holding devices thereon, but excluding approvedsafety devices and tyre buJge due to load.
