BITUMEN BOUND MATERIALS Components of a Mix HIGHWAY II - Bitumen Bound Materials 31 The coarse aggregates for premixes should be produced by crushing sound, unweathered rock or natural gravel. The aggregate must be clean and free of clay and organic material; the particles should be angular and not flaky.
Although highway technology has changed markedly since, principal road layers still consist of a mixture of stone, in the form of graded aggregate, and binder, in the form of a petroleum bitumen or a derivative of petroleum bitumen. Engineers today have a wide choice of materials available for road pavement construction.
