Polished asphalt exposes the aggregates in the asphalt course and is done to promote the various colours existing between the bond and the aggregates. With a polishing action, the choosen aggregates are highlighted. This way, you can get various results depending on the colours and the grading (classement of the aggregates).
The final result has the look of polished concrete or marble. It has a very smooth surface with a high quality feel and maintains the original properties of the asphalt.
Compared to the shot blasting method, polished asphalt gives an important brightness to the surface. The aggregate is successfully roughened without causing damage to the asphalt course.
