The suitability of the aggregates for the construction of base course and asphalt layers of a pavement is determined by various parameters-properties. One of these properties is aggregate cleanliness. The two basic tests that determine the cleanliness of the aggregates are the sand equivalent test and the mcthylene blue test. In the present paper, firstly, a reference is being made to the two tests and to the limits used by international standards. Secondly, relevant results are presented from a significant number of limestone and 'non-limestone1 aggregates. From the results obtained it is concluded that sonic aggregates with acceptable sand equivalent value do not satisfy the methylene blue requirement. Similarly, aggregates that do not satisfy the sand equivalent requirement are suitable to be used in highway engineering.
