DESIGN OF HOT ROLLED ASPHALT BY THE MARSHALL METHOD

An extensive programme of experimental work has indicated that if reliable results are to be obtained using the Marshall apparatus, all aspects of the procedure should be consistent from one specimen to the next. If possible all specimens for a complete mix design should be manufactured without interruption. A summary of experimental work is given and the author concludes that: (1) no practical problems are encountered in applying the Marshall procedure in its present form to hot rolled asphalt wearing course mixtures with coarse aggregate contents up to 55 per cent by mass; (2) optimum binder contents for the total mix, as the mean of the binder contents corresponding to maximum stability, maximum mix density and maximum compacted aggregate density, are on average 0.7% by mass below the target binder contents determined in accordance with BS 594 (1973); (3) over emphasis on achievement of improved resistance to deformation may result in premature failure due to other causes. Care must be taken to ensure that adequate durability, flexibility and compaction are also achieved. (TRRL)
