BEHAVIOUR OF CALCRETES AS FLEXIBLE PAVEMENT MATERIALS IN SOUTHERN AFRICA

This paper reviews the behaviour of calcretes as flexible pavement materials in Southern Africa. Calcretes ranging in properties from those of loose soils to hard rock contribute the most widely used class of road material in Southern Africa. Their unusual composition, origin and properties and the relatively dry climate in which they are used limits the applicability of traditional materials standards. Although calcretes do present certain problems, their behaviour as flexible pavement materials is generally better than that suggested by traditional standards, and empirical standards derived from a local study of the performance of calcrete bases, subbases and wearing courses are presented (a). The number of the covering abstract of the conference is TRIS No. 368448. (TRRL)
