FOREWORD
This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by
the Bitumen, Tar and Their Products Sectional Committee had been approved by the Petroleum, Coal and Related
Products Division Council.
This standard was first published in 1978 and was subsequently revised in 1995. The first revision incorporated
certain new tests and the deletion of obsolete ones. The standard was revised in 2004 to include new types of
emulsion grade. Both the rapid setting (RS) and slow setting (SS) grade were sub divided into two grades based
on the differences in the requirements of viscosity, storage stability & residues. Methods of tests for determination
of residue on sieving and coating ability and water resistance were updated. Considerable assistance was derived
from ASTM D2397 in preparation of second revision
Cationic bitumen emulsion usage in India increased substantially since the introduction of the revised specifications
in 1995. The usage of emulsion as a percentage of total bitumen usage also went up. Ministry of Road Transport
& Highways (MoRTH) specification for road works had substantially widened the scope for emulsion usage in
various road applications.
This revision (third) of standard is undertaken due to various problems associated with technical requirement of
SS 1 grade bitumen emulsion as this emulsion is inverted emulsion and various properties/requirement of SS 1
were not relevant to requirement of prime coat applications. Based on the comments received on the standard the
present revision of this standard is taken up mainly to incorporate revised requirement for Slow Setting-1 grade of
bitumen emulsion given in Table 1. The revised standard is in order and take care of application issues associated
with SS1 emulsion. Properties specified in revised standard will benefit highway profession.
The recommended uses of five grades of emulsified bitumen of the cationic type prescribed in this standard are
given in Annex A.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960
‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded off
value should be the same as that of the specified value in this standard.
