7 Draft for Comments Only DOC: PCD 6 (10471) C BUREAU OF INDIAN STANDARDS Draft Indian Standard SPECIFICATION FOR CUTBACK BITUMEN (Third Revision) ICS Not to be reproduced without the Last date for receipt of comments: permission of BIS or used as STANDARD 0. FOREWORD 0.1 (Adoption clause will be added later.) 0.2 This standard was published in 1951, and was revised in 1961 in view of the publication of IS : 1201 to The second revision was carried out to update the standard in accordance with the revised version of IS: 1201 to In second revision, six grades of rapid curing type (RC), medium curing type (MC) and slow curing type (SC) have been unified into four grades, five grades and four grades respectively, which were produced and marketed in the country. 0.4 In this revision bitumen produced from coal tar has been deleted from scope and definition of RC and MC have been updated. Further MC 70 grade has also been allowed to be used as primer. 0.5 This standard is one of the series of Indian Standards on bitumen. Other specifications so far published in the series are: IS: Paving bitumen IS: Digboi type cutback bitumen (revised) IS: Industrial bitumen (second revision) 0.6 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.

8 1. SCOPE 1.1 This standard covers the physical and chemical requirements of cutback bitumen produced by fluxing bitumen with distillates of petroleum for use in road construction. 2 REFERENCES The following standards contain provisions which, through reference in this text, constitute provisions of this standard.

These shall be used with aggregates containing less than 40 percent of fine aggregates passing through 2 36 mm sieve and shall be classified into five grades with designations: a) MC 30, b) MC 70, c) MC: 250, d) MC 800, and e) MC: MC 30 and MC 70 grades shall be used as primer Slow Curing Slow Curing- (SC) These shall be used with aggregates containing more than 20 percent of fine aggregates passing through 2'36 mm sieve and shall be classified into four. Grades with designations: a) SC 70, b) SC 250, c) SC 800, and d) SC MANUFATURE AND SOURCE 4.1 The material shall be prepared by fluxing bitumen with distillate from petroleum. 4.2 The source and type shall be stated by the manufacturer.

10 5. REQUIREMENTS 5.1 Rapid curing cutback bitumen shall comply with the requirements specified in Table Medium curing cutback bitumen shall comply with the requirements specified in Table Slow curing cutback bitumen shall comply with the requirements specified in Table TESTS 6.1 Tests shall be carried out a described in the appropriate Indian Standards specified in col 7, 8 and 7 of Table 1, 2 and 3 for rapid curing, medium curing and slow curing cutback bitumens, respectively. 7. PACKING AND MARKING 7.1 Packing- The material shall be supplied in drums according to IS: or as agreed to between the purchaser and the supplier. 7.2 Marking- Each container of bitumen shall be legibly and indelibly marked with the following: a) Manufacturer s name of trade-mark, if any; b) Month and year of manufacture; c) Type and grade of material; and d) Batch number BIS Certification Marking Each length of the hose may also be marked with the Standard Mark The use of the Standard Mark is governed by the provisions of the Bureau of Indian Standards Act, 1986 and the Rules and Regulations made thereunder. The details of conditions under which the licence for the use of the Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards. 8. SAMPLING 8.1 Representative sample of the material shall be drawn and their conformity of the requirements to this standard be judged as prescribed in Appendix A.

13 A.1. SCALE OF SAMPLING A1.1 Lot- In any consignment all the containers of the same type, same grade and belonging to the same batch manufacture shall be grouped together to constitute a lot. A-1.2 The number of containers to be selected from the lot shall depend upon the size of the lot and shall be in accordance with Table 4. TABLE 4 SCALE OF SAMPLING LOT SIZE NUMBER OF CONTAINERS TO BE SELECTED 1 2 Up to 5o 3 51 to to and above 10 A-1.3 These containers shall be selected at random from the lot. In order to ensure the randomness of selection, procedures given in IS: may be followed. A-2 PREPARATION OF TEST SAMPLES A-2.1 From each of the containers selected according to A-1.2 and A-1.3, a sample representative of the material in the container shall be drawn in accordance with the methods prescribed in IS: , taking all the precautions mentioned therein. All these samples from individual containers shall be stored separately. A-3 NUMBER OF TESTS A-3.1 All the individual samples shall be tested for kinematic viscosity, flash point and ductility. A-3.2 For the remaining characteristic given in Table1, Table 2 and Table 3 of specification, a composite sample prepared by mixing together approximately equal quantities of bitumen form all individual samples shall be tested. A-4 CRITERIA FOR CONFORMITY A-4.1 The lot shall be declared as conforming to the requirements of this specification if A and A are satisfied. A From the test results of each of the characteristics given in A-3.1 the mean (X) and the range (R) shall be calculated as below:

14 Mean (X) =sum of the test results number of test result range (R)= difference in the largest and the smallest of the test result. If the expression ( X-0.6 R) is greater than or equal to the minimum specification limit, the expression (X+0.6R) is less than or equal to the maximum specification limit and both the conditions are satisfied in cast of two sided specification limits, the lot shall be considered to have met these requirements. A The composite sample, when tested for the characteristics mentioned in A-3.2, shall satisfy the corresponding specification requirements.
