Recommendations for laying, information for enquiries and/or orders appended.

This British Standard gives requirements for mastic asphalt with natural rock asphalt fine aggregate for roads and footways. Appendix A and Appendix B contain, respectively, recommendations for laying and a list of information to be given in enquiries and/or orders.

NOTE 1 It is appreciated that with the publication of this metric standard it would be impractical for suppliers to be contractually obliged to supply to the metric grading limits given in Table 2 and Table 3. During the transitional period from imperial to metric units and until such time as screening equipment based on imperial sizes is replaced by new equipment conforming to metric requirements, material supplied to the grading limits given in BS 1446:1962 will be considered equally applicable with material supplied to the grading limits given in Table 2 and Table 3 of this standard. For this purpose the 1962 limits are given in Appendix C of this edition. The supplier should, however, state in his advice note to the purchaser whether he has supplied to imperial or metric grading limits.

NOTE 2 The titles of the British Standards referred to in this standard are listed on the inside back cover.
