Bitumens modified with recycled polymers [PDF]
Materials and Structures, 2000 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 investigates the possibility of using ...
