RAPID METHODS OF ANALYSIS FOR BITUMINOUS ROAD MATERIALS

THE FIRST EDITION OF ROAD NOTE NO. 10 APPEARED IN 1951 AND WAS INTENDED TO BE A HANDBOOK FOR ANALYSTS WHO WISHED TO USE THE METHODS RECENTLY DEVELOPED AT THE ROAD RESEARCH LABORATORY IN GREAT BRITAIN, FOR ANALYSING PREMIXED BITUMINOUS MATERIALS IN A TIME VERY MUCH SHORTER THAN THAT WHICH COULD BE ACHIEVED USING THE METHODS SPECIFIED IN BRITISH STANDARD 598:1950. IN THE PRESENT VERSION, THE AIM IS TO REMOVE ANY AMBIGUITIES AND UNCERTAINTIES IN THE PROCEDURE AND TO GIVE CLEAR GUIDANCE WHERE ALTERNATIVES ARE PERMITTED. SOME REVISIONS IN THE PROCEDURE HAVE BEEN MADE. A TABLE GIVING EXTRACTION TIMES FOR DIFFERENT TYPES OF MATERIAL WHEN USING THE SIEVING-EXTRACTOR METHOD HAS BEEN ADDED, TOGETHER WITH INSTRUCTIONS FOR REDUCING THE ANGLE OF OSCILLATION OF THE HEAD WHEN SAMPLES CONTAINING WEAK OR SOFT AGGREGATES ARE BEING ANALYSED. A BRIEF DESCRIPTION OF THE 'AUTOMATIC' RECOVERY OF THE BINDER FROM SOLUTION IS INCLUDED. OTHER SUBJECTS DISCUSSED ARE THE DIFFERENCES IN RESULTS OBTAINED RESPECTIVELY BY WET AND DRY SIEVING, THE ANALYSIS OF MIXTURES CONTAINING NATURAL ASPHALTS, THE RECOVERY OF DICHLOROMETHANE, THE SAFETY PRECAUTIONS THAT SHOULD BE OBSERVED WHEN CARRYING OUT THE ANALYSIS, AND THE USE OF TRICHLOROETHYLENE AS AN ALTERNATIVE SOLVENT IN HOT CLIMATES. /AUTHOR/
