AbstractAddition of 40% of Phosphogypsum ( Pg ) and Cement Klin dust ( CKD) to Asphalt has given encouraging results including penetration , softening , Flash point an fire point identical to the accepted properties of industrial asphalt.
Chlorination of Natural Asphalt at 1.5 hr the same additive of 40% in the presence of Fe2O3 as catalyst have affered optimizing rhealogy and thermal properties.
The FT-IR and UV identifications have indicated the existence of clear groups as aresult of chlorination and additives.
The microscopic study for floor samples have shown the good atomic distribution to floor asphalt .Generalty results on the modified natural asphalt ( Heet- Abo- Aljeer ) have proved the capability of using it in paving instead of Industrial asphalt .
