Study On Stability Of SBS Elastomer Modified Asphalt

The modified asphalt technology gets the extensive use in two big domains at present: Building waterproof as well as flexible road surface. With the height the enduring temperature capability to raise asphalt and his use temperature region of enlargement and lengthens his service life serve as the purpose , and joins the high polymer , thus what gets one kind mixes the system altogether , we call it modified pitch.Modified pitch has many kinds , and that the modified asphalt of elastomer is to apply the most important one kind.Along with constantly applying of modified pitch , people find that the problem of whole modified system stability directly influences his use and preservation and transportation gradually .Study carefully his cause , and chiefly is owing to pitch and the molecular weight of the high polymer material of modified usefulness differs too big , and makes half-stability's state of modified system in most of circumstances temporary lodges . This has directly influenced the application and popularization of modified asphalt.This text is on the stability research foundation of modified pitch of SBS , and each component part to pitch on foundation in mixing the system altogether , and the effect memory focal point to the whole system stability is studied The major research conclusion is as follows:1. The SBS who joins fixed capacity can improve the middle aspect capability of pitch system in the fixed level.2. Each component part of pitch has different show and effects to the whole system stability in the modified pitch system of SBS.3. the course modified at pitch , referring and mixing the method also has the different shows to the stability of whole system...
