This method describes a procedure for determining the crumb rubber content of a digested crumb rubber modified binder. The concentration of rubber can be lower than the original composition would suggest due to the potential loss in the digestion process. This test determines the particulate rubber content of digested crumb rubber/bitumen binder mixtures used for sprayed sealing work.
