Research On Properties Of Interal Modified Bitumen

In this paper,based on the understanding of the researching situation and development trend of modified bitumen from both national and abroad,studied on a new material which is named Interal,it is a non-polymer inorganic material which mainly contain AlCl3 to used to modified bitumen and composite modified bitumen,basically when it is mixed together with Petroleum bitumen and SBS modified bitumen,so as to exploit synergies,and improve the research,development as well as application of composite modified bitumen.This paper illustrated the performances of different dosage into the Petroleum bitumen and SBS modified bitumen,also study mechanism of the Interal composite SBS modified bitumen by modern analysis technology IR.Furthermore,this study conducted numerous experiments to research how Inteal composite SBS modified bitumen impact on its AC-13 mixture.Study found that:(1)Interal mixed with basis bitumen can improve bitumen’s performace which includes high temperature stability,sensitivity for temperature,aging resistance,low temperature cracking resistance and safety.(2)Interal Built SBS modified bitumen can improve bitumen’s performace which includes high temperature stability,sensitivity for temperature,aging resistance,safety,elastic recovery except for low temperature cracking resistance.(3)AC-13 mixture which made by Interal composite SBS modified bitumen,has good performace includes high temperature stability,low temperature cracking resistance,water stability with a suitable dosage of Interal.
