The highway engineer confronted with the problem of designing or testing bituminous paving mixtures has access to a greatvariety of design methods and criteria. Many papers and learned discussions have been published and the engineer has a widevariety to choose from in selecting a method that best suits his fancy. In selecting a method, however, the engineer should askhimself the pertinent question: Do the results obtained by this method distinguish not only between a good pavement and anobviously unsatisfactory pavement, but also can the intermediate or so-called borderline cases, often involving local materials beidentified. A borderline mixture can either be eliminated or one of several methods may be employed to improve its quality such asthe addition of a filler, coarse rock or perhaps a more viscous type of bituminous binder. A design method which will enable you toselect with a reasonable degree of confidence some nearby local deposit of suitable aggregate in preference to importing a costlymaterial from some distant proven source would appear, from the economical standpoint to be the most satisfactory method.
Some of the more commonly known design methods in use include the:Hubbard Field Method, Marshall Method, Bureau of Public Roads--- Unconfined, Compression Test, Asphalt Institute Method
(Triaxial), Hveem Stabilometer Method and of course the all important method for proportioning the "Right" amount of asphalt by"Experience". True, experience is a wonderful teacher but any method to be successful has to be "Right" in practically all cases withall types of aggregates, whether it be the native soil, uncrushed gravel or crushed quarry rock. Also, the method has to be "Right"whether the bituminous binder consists of liquid asphalt, asphaltic emulsion or paving asphalt.
