Glass asphalt advantages:

�Glass asphalt surfaces are more reflective than conventional asphalt

- improves night time road visibility.

� The surface dries faster than traditional paving after rain because the glass particles do not absorb water.

- increase road safety

� Thousands of tones of waste glass now being sent to landfill sites can be used in asphalt production to improve the asphalt properties

- environmental & technical

� Due to the glass content the asphalt will hold heat longer than conventional asphalt

- easier to work and compact
