... emulsion macadam (DBEM), have been studied in the laboratory using the repeated load axial test (RLA). A conventional emulsion and SBS and EVA polymer modi®ed emulsions have been used to investigate the in¯uence of polymer modi®cation on the resistance of mixtures to permanent deformation. The base binder...

... isa necessary requirement and, hence, the Repeated Load Axial(RLA) Test hasbeen developed at Nottingham. This was done orig- inally very much in the contexotf mixture design. The test configuration is shown in Fig. 2(c) and usually involves a test specimen 10 10 1o2 103 1o4 Cycles to failure Fig. 9...
