SALT HEAVING IN THE SAHARA

Salt damage to pavements has been studied on the roads of the Algerian Sahara and particularly on the runway of the old airport of Adrar. Salt damage results from the heaving of the priming coat and the asphalt wearing course by salt whiskers growing vertically from the capillary pores of the base course. The salt concerned with salt heaving in the Sahara is generally halite (NaCl) which is the most widespread salt in nature. Salt heaving shows striking similarity with frost heaving. Methods to prevent salt heaving as well as methods to repair salt damage are discussed. (TRRL)
