The present study contained performingMutual Chemical and PhysicalModification of (-Abo aljear) Nutral Asphalt by using Iraqi material on the forme west toachieve tow Modification Asphalt and to refine environment because it poisoning materials The Modification in this Study includes two Routes:- 1 – The Physical rout :- Add both materials phosphogysum ( Pg.) and cement kiln dust ( KCD ) to Natural Asphalt after refining it to form water. The percent of blend (10% ,20% , 30% ,40% wt ) in pores size 75μm . and measure Rheological traits wich include ( Penteration , Softening ) it has given identical results the Optimization percentage is ( 40% Pg. & CKD ). And we make hot measurement which includes ( Flash point , Fire point, ) it has given good result specially by using rathio 40% for both material .in blend Temperature 90 . 2 –The Chemical Route :- perfoming four chlorination processes on natural asphalt the time of calorination( 0.5 hr , 1 hr, 1.5 hr , 2 hr) by uses Fe2O3 as acatalyst after add material (Pg. ,CKD ).in the same Blends percentage and mesurment Rheology&thermal properties. The good result it in 1.5 hr colorenation in 40% of material add. The Spectroscopy study of the samples by using infrared chlorine gas besides addition both materials add. The light were identical to previous studies .and the microscopey study for floor samples.the pictures have shown the existence of similiarity and good atomic distribution to for floor asphalt .Generally this study has excellent results in modification natural asphalt ( Hiet-Abo aljear ) and the capability of its using in stead
