Abstract. Waste rock materials are becoming widely used in road pavement and building constructions in many countries. In this work, experimental laboratory tests were carried out on the waste rock produced from the extraction of the phosphate in the Kef-Essenoun mine, to study the performance of road pavement foundations built with these types of material.

To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees. Adding it to the soil surface may not be as effective. If you have a well-established lawn and trees, scatter the rock phosphate over the landscape. Gently rake it into the soil to ...
