It supersedes BS 594-1:2002, which is withdrawn. The previous edition of BS 594-1 introduced the follow
12、ing changes: bitumen grade references in accordance with BS EN 12591; terminology which will be used in future European asphalt standards to familiarize UK users with the new terms; reference to the in-plant blending of bitumens; requirements for the specification of surface course mixtures based on
13、 their resistance to deformation; the design type R surface course mixtures were deleted. This edition introduces the following changes. The requirements for aggregates, the sieve sizes used for the definition of mixtures and the size designations of mixtures have been amended to align with BS EN 13
14、043, which is being implemented in the UK on 01/01/2004. The introduction of BS EN 13043 implies the use of both different size designations and test methods. Detailed guidance and advice on the changes may be found in PD 6682-2 and PD 6682-9. BS 594 comprises two parts: Part 1: Specification for co
15、nstituent materials and hot rolled asphalt mixtures; Part 2: Specification for the transport, laying and compaction of hot rolled asphalt. This part includes requirements for asphalt mixtures and their constituent materials and for coated chippings applied to the surface of some asphalt surface cour
16、ses. The requirements and recommendations for transporting asphalt and for site work are given in BS 594-2. Over the years, a considerable number of hot rolled asphalt mixture compositions have evolved. During the preparation of this revision, some rationalization of the previous range has been unde
17、rtaken by omitting the type R enriched mixtures. The limited range of preferred mixes introduced in the previous edition and identified in bold type in Table 2, Table 3, Table 4 and Table 6, is maintained. As mixtures suitable for most uses can be selected from this reduced range, the use of a prefe
18、rred mixture is encouraged wherever possible. Further guidance on the selection of mixtures, the application of design test criteria and recommendations for stability related to traffic conditions, and information to be provided by the purchaser and the supplier is given in Annex A, Annex B, Annex C
19、, Annex D and Annex E. The requirements for the composition of all asphalt mixtures are based on testing the constituents and the mixture by methods described in BS 598 and other British Standards (see Clause 2). Adjustment values for soluble binder content and material passing the 0.063 mm test sie
20、ve are given in BS 598-102. Methods of test to determine the condition of the binder on coated chippings and their rate of spread, the texture of finished surfaces, the density of cores drilled from asphalt surfacing and a method for assessing the compaction performance of other rollers by compariso
21、n with the performance of a non-vibrating 8 t roller are included in other parts of BS 598 (see Clause 2). It has been assumed in the drafting of this part of BS 594 that the execution of its provisions is entrusted to appropriately qualified and experienced people. This publication does not purport
22、 to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not in itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, page

24、specifies the properties of materials used to make hot rolled asphalt and of the mixtures manufactured from those materials. Base (roadbase), binder course and regulating course mixtures are specified by conventional recipe methods in 5.1. Surface course mixtures are specified in three ways. In 5.2
25、design mixtures are specified, based on the mechanical testing of the asphalt mixture to determine a design binder content. This binder content is of particular value when dealing with aggregates of previously unknown performance. Design mixtures are recommended for use on heavily trafficked roads.
26、Since the previous revision of this standard, mixtures have been developed which are suitable for use on very heavily trafficked sites. These are now specified in 5.4 (performance specified mixtures). No mix design method is specified. Instead, the as-laid asphalt mixtures are specified in terms of
27、their resistance to deformation under varying degrees of traffic stress, from moderate to the most severe. The recipe type of surface course mixture specified in 5.3 is the conventional mixture which has proved satisfactory, except under heavy traffic, for most applications for many years. Where hot
28、 rolled asphalt surface course mixtures, of nominal 35 % coarse aggregate content or less, are used in trafficked areas it is usual to apply coated chippings to provide a suitable level of skidding resistance to the finished road. The properties of such chippings and the requirements for their manuf
29、acture are specified in Clause 7. 1 Scope This part of BS 594 specifies requirements for mixtures of hot rolled asphalt to be laid as surface course, regulating course, binder course or base (roadbase) on roads and other paved areas, excluding heavy duty airfield pavements. It also specifies require
30、ments for coated chippings, but excludes requirements for site-specific properties such as polished stone values and abrasion values of aggregates. NOTEThe terms “base (roadbase)”, “binder course” and “surface course” are used throughout this standard in place of the traditional terms “roadbase”, “b
31、asecourse” and “wearing course” respectively to encourage use of the new terminology which will be used in European asphalt standards to be introduced in the near future. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute pro
