The influence of boundary conditions on the healing of bitumen

Damage in pavements is known to reduce over time when the material is left to rest, this phenomenon is identified as healing. It has been shown that healing has a large influence on pavement performance. However, as the healing mechanism is not fully understood, there is currently no accepted method available to assess the healing performance...

Direct Tensile Test to Assess Healing in Asphalt

Asphalt concrete has the advantageous ability to heal. During rest<br/>periods, damage present In the material is restored to a certain extent.<br/>Healing of the material can be observed in iis regaining of strength<br/>and stiffness after rest periods. In this paper, a new test method is presented.<br/>It was developed to increase the...
