Increasing traffic loading and volumes on roads has led to the use of polymer modified binders to improve the performance of bitumen in terms of additional strength, durability and increased resistance to rutting and fatigue cracking. Generally those modifiers currently in use are virgin polymers but the research investigate the possibility of using waste polymers instead. The aim was to find a...

Bitumens extracted from 2.7 to 2.5 billion-year-old (Ga) shales of the Fortescue and Hamersley Groups in the Pilbara Craton, Western Australia, contain traces of molecular fossils. Based on a combination of molecular characteristics typical of many Precambrian bitumens, their consistently and unusually high thermal maturities, and their widespread distribution throughout the Hamersley Basin, th...

Promoting the use of scrap tire rubber and bio-modifiers in outdoor construction such as road pavements requires an in-depth understanding their resistance to solar radiation which causes premature aging constructions. Aging changes bitumen's colloidal stability, increasing content asphaltenes, decreasing aromatics progresses. Bitumen's during include oxidation, aromatization, chain scission, c...

In recent decades, the application of modified bitumens has experienced tremendous growth. However, due to varying modification mechanism different modifiers, creep and recovery properties bitumen have not been comprehensively understood. This study aims evaluate several representative using multi-stress (MSCR) test. The MSCR test can highlight unique delayed elasticity it uses a high stress le...
