Evaluation of abrasion loss of asphaltic concrete subjected to ageing

Road pavements like other civil infrastructures have a service life. Asphalt Pavements get aged and become weaker, as well the pavement faces abrasion loss of their particles when a huge traffic volume uses on it. Bitumen plays an important role for the ageing of asphaltic concrete pavement. In prev...
