FOREWORD
This Indian Standard (Part 2) (Third Revision) wasadopted bytheBureau ofIndian Standards, after thedraft
finalized bytheConstruction Plant andMachinery Sectional Committee hadbeen approved bytheMechanical
Engineering Division Council.
The single drum vibratory rollers are versatile compacting machines andcanbeused for alltypes of soilsand
under various conditions. The success ofvibratory rollers liesintheir ability tocompact awide range ofsoils
indeeper liftsandinlesstimethantheconventional compacting equipment. The vibration induced tothesoils
reduces the friction between the particles of the material which are reoriented and brought closer together as
air voids areeliminated, thusbinding thematerial intodenser state. Further compaction results from the static
loadandthecentrifugal forceappliedbythevibratingrollonthematerialtobecompacted. Thetotalcompacting
force ofavibratory roller is,thus, significantly morethanthemassofthemachine.
Thisstandard wasfirstpublished in 1969covering thegeneralrequirements forbothself-propelled singledrum
anddouble drum (tandem) vibratory rollers. Thefirstrevisionwastakenupin 1977toincorporate modification
in the provisions relating to speed, fuel system, manufacture, etc. As a result of increasing use of different
types of vibratory rollers in earthwork and road construction in our country, suggestions were received for
preparing separate standards for vibratory rollers of single drum and tandem drum. Accordingly, the second
revision of the standard was taken up in 1992to cover only self-propelled heavy duty single drum vibratory
rollers. Vibratory rollershavegoneovervarioustechnicalmodifications inthelastfewyearsandneed wasfelt
torevise thestandard toalign itwithcurrent manufacturing practices.
Inthepreparation ofthisstandarddueconsideration hasbeengiventotheprovisions ofCentral Motor Vehicles
