It is a partial revision of BS 3690-3:1983 which is now withdrawn. All
10、types of bitumen for building and civil engineering are covered in BS 3690 as follows. BS 3690, Bitumens for building and civil engineering. Part 1: Specification for bitumens for roads and other paved areas; Part 2: Specification for bitumens for industrial purposes; Part 3: Specification for mixtu
11、res of bitumen with pitch, tar and Trinidad lake asphalt. Part 3 is based on normal practice in the UK and relates only to the climate, conditions and application techniques encountered here. It specifies the properties known to be important and the relevant test methods. Many combinations of bitume
12、n with tar, pitch or refined lake asphalt are possible but the coverage of this standard has been limited to the more commonly available mixtures that are used as binders for roadways and footways. A limited number of lake asphalt-bitumen mixtures are described. This type of mixture is used in build
13、ing mastics and the range specified in this standard will be extended if experience shows this is desirable. A system of grades and nomenclature has been adopted based on the mid-point of the permissible penetration or viscosity range as appropriate. It is considered that this makes specifying and o
14、rdering easier. This edition introduces technical changes to bring the standard up-to-date but it does not reflect a full review of the standard, which will be undertaken in due course. The main changes from the previous edition are clarification of the title to exclude polymer blends which will be
15、covered separately and the updating of definitions and test method references. It is not the function of this standard to specify which of the bitumen mixtures should be used for individual applications. Appropriate British Standards are BS 594, BS 1446, BS 1447 and BS 4987. Other useful publication
16、s are: Road Note 39 Recommendations for road surface dressing (Transport and Road Research Laboratory, Department of the Environment and Department of Transport); Specification for Highway works (Department of Transport). This Part of this British Standard requires the use of substances and procedur
17、es that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage. Acknowledgement is made to the Standardization of Tar Products Test Committee (STPTC) for
18、 permission to use STPTC PT3-79 which appears in Appendix C. It is intended to produce a Part 4 to BS 3690 which will be a specification for modified bitumens including their testing. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standard
19、s are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. In particular, attention is drawn to the Health and Safety at work, etc. Act 1974. Summary of pages This document comprises a front cover, an inside front co
20、ver, pages i and ii, pages 1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. BS 3690-3:1990 BSI 04-19991 1 Scope This Part of this stand
21、ard specifies classification, composition and properties of pitch-bitumen mixtures, tar-bitumen mixtures and lake asphalt-bitumen mixtures that are suitable for use in road and industrial applications in the UK. Each mixture is classified into a number of grades for each of which the appropriate des
22、ignation and properties are specified. Advice on handling and packaging, and on sampling and testing is given in Appendix A and Appendix B. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of this standar
23、d, the following definitions apply. 2.1 bitumen a viscous liquid, or a solid, consisting essentially of hydrocarbons and their derivatives, which is soluble in trichloroethylene and is substantially non-volatile and softens gradually when heated. It is black or brown in colour and possesses waterpro
24、ofing and adhesive properties. It is obtained by refinery processes from petroleum, and is also found as a natural deposit or as a component of naturally occurring asphalt, in which it is associated with mineral matter 2.2 pitch the black or dark brown solid or semi-solid residue remaining after the
