SPECIFICATION FOR MASTIC ASPHALT (NATURAL ROCK ASPHALT FINE AGGREGATE) FOR ROADS AND FOOTWAYS

THIS METRIC REVISION REPLACES THE EARLIER IMPERIAL STANDARD. ITS SCOPE AND THE TERMS USED ARE DEFINED. SAMPLING AND TEST METHODS ARE SPECIFIED BY REFERENCE TO BRITISH STANDARDS. A TABLE SETS OUT THE TEST LIMITS (PENETRATION, SOFTENING POINT LOSS ON HEATING, PENETRATION OF RESIDUE AFTER HEATING, SOLUBILITY AND ASH CONTENT) FOR THE PERMITTED CEMENTS (BITUMENS, REFINED LAKE ASPHALT OR A MIXTURE OF BOTH). LIMIT ARE ALSO GIVEN FOR THE BITUMEN CONTENT, APPARENT SPECIFIC GRAVITY AND CALCIUM CARBONATE CONTENT OF THE NATURAL ROCK ASPHALT FINE AGGREGATE AND FOR THE GRADING OF THE COARSE AGGREGATE. REQUIREMENTS ARE GIVEN FOR THE QUALITY AND TYPE OF COARSE AGGREGATE, AND FOR THE COMPOSITION AND MANUFACTURE OF THE ASPHALT ITSELF. A TABLE LISTS THE LIMITS OF COMPOSITION BY ANALYSIS (BITUMEN CONTENT AND GRADING OF MINERAL MATTER). DETAILS ARE GIVEN FOR REMELTING ON SITE. THREE APPENDICES RESPECTIVELY DEAL WITH RECOMMENDATIONS FOR LAYING, INFORMATION TO BE GIVEN WITH ENQUIRIES AND ORDERS AND A VERSION OF THE STANDARD FRAMED IN IMPERIAL UNITS FOR USE DURING THE TRANSITION TO METRIC UNITS. /TRRL/
