The recommended uses of five grades of emulsified bitumen of the cationic type prescribed in this standard are given in Annex A. nearly 60-65 percent of emulsion is used in tack coat applications. It has been proven that an emulsion with a higher viscosity range is ideally suited for such application.

The international status for emulsion usage is 10 percent of total bitumen usage. Out of the present emulsion consumption. In this revision the following changes have been made: a) Rapid setting (RS) grade emulsion has been divided into two different grades of emulsions. new types of emulsion grades have been incorporated in this revision. PCD 6 FOREWORD This Indian Standard (Second Revision) was adopted by the Bureau of Indian Standards.1 and RS-2 grades.0 Max since it is revealed that there is a tendency for emulsions manufactured with lower binder content to have less storage stability but this does not seriously alter the life or the other characteristics of the emulsion.Bitumen. Cationic bitumen emulsion usage in India has increased substantially since the introduction of the revised specifications in 1995. observed or calculated. single coat/two coat surface dressing including synchronized surface dressing is being carried out to improve the road connectivity at low cost especially in rural areas. d) The modifications have given in Amendment No. slow setting (SS) emulsion has also been divided as SS-1 and SS-2 emulsion. . The viscosity of this emulsion is suggested at a lower range between 20-100 SFS at 50°C for ease of application and good coverage on the existing surface (especially since the method of application is still manual in most cases). Tar and Their Products Sectional Committee. The usage of emulsion as a percentage of total bitumen usage has gone up from 1 to 3 percent in the last five years. Requirements been included for SS. This standard was first published in 1978 and was subsequently revised in 1995. The suggested viscosity range for RS-2 is similar to ASTM CRS-2 from 100 to 300 SFS at 50° C. The storage stability has been suggested as 2.1 and SS-2 grades also. Considerable assistance has been derived from ASTM D 2397 in formulation of this standard.1 emulsion and RS-2 emulsion. The proposed revised Ministry of Surface Transport (MOST) specification for road works is expected to substantially widen the scope for emulsion usage in various road applications. The composition of the Committee responsible for formulation of this standard is given in Annex K. The first revision inco~orated certain new tests and the deletion of obsolete ones. The aforesaid emulsion is called as RS. the final value. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. c) Method for determination of residue on sieving on 600-rnicron IS sieve (see Annex B) and coating ability and water resistance (see Annex F) have been updated.1 emulsion.
