Gives analytical methods of testing under laboratory test conditions on samples of bituminous metals. Does not apply to mastic asphalts. NOTE:- It may be possible to obtain accurate binder content results by use of an adjustment factor for insoluble matter based on information provided by the modified binder supplier.
