The Stress Relaxation Of Modified Bitumens

Bitumens Modified with Recycled Polymers

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...

Phase-Destabilization Mechanism of Polymer-Modified Bitumens in Quiescent Annealing

Bitumen as a binder in coating and insulating materials is modified with polymers to improve its performance in service conditions. Almost all polymers are incompatible with bitumen, and at high temperatures due to relatively very low viscosity of the bitumen phase, are separated from it. These lead to a considerable limitation in the use and handling of polymer-modified bitumens. An understand...

Comparison of the Effectiveness of Relaxation and Cognitive-Behavioral Hypnosis Therapy on Children's Stress

Background and Objectives: Mental calming techniques including relaxation and cognitive-behavioral hypnotherapy, are very important because they induce relaxation, a pleasant feeling and a sense of well-being. Therefore, the aim of this study was to determine the effectiveness of relaxation and cognitive-behavioral hypnosis therapy on children's stress. Materials and Methods: In a quasi-experi...
