    This is a physical change.

    Explanation:

    Hot asphalt is mixed with the sand crushed stones and spread onto the roads, when it gets dry it becomes hard giving a smooth straight surface of the road.

    Asphalt is used to stick together stones and sand in the road.

    It is a physical change because the phase of the asphalt changed from the liquid to solid.

    At high temperature, asphalt is in liquid form and at room temperature, it is present in hard solid form.
