Specification, part 1

The Commonwealth Department of Construction has in the past based its design, specification and control of bituminous concrete on the marshall test. The current practice for the more important jobs is to specify the quality and quantities of mix ingredients; a streamlined marshall test is used to quickly indicate total mix properties so that production control can be affected. Whether an end product or methods specification is used the testing is designed to ensure that only "in spec" material is placed in the works, rejected material being diverted to jobs of lesser importance where this can be arranged. This is considered to be a major advantage of the system and benefits both the supplier and the client. Mix types and the methods of specifying and controlling bituminous concrete work differ from those of other authorities in some respects and such differences can mostly be attributed to the particular problems of the airfield situation and to the relatively small number of pavements controlled by the department.
