Bituminous surface dressing is a constructional methodology of pavement surfacing.It is u-sually used to form a pavement of strong base and thin surfacing.Its procedure comprises several co-herent stages.The amount of quality control points is relatively big.The quality control points of the procedure of double surface dressing on requirements of base,quality of materials,control of con-struction proceedings,curing of pavement structures,and etc.,are summarized in this paper based on the Rehabilitation/Upgrading of Selected Urban Roads in Lusaka City Proj ect in Zambia,southern Af-rica.The defects produced due to quality control failures during construction of double surface dress-ing are discussed and analyzed and the respective remedial methods are concluded.It could be used for reference for construction of similar proj ect.
