The binder in concrete is usually cement. Cement causes the aggregate and sand to bind together mechanically and harden to make a solid surface.
Asphalt roads look similar in nature to concrete because both use an aggregate material consisting of rocks to make up as much as 60% of the volume of the final solid material.
It's a solid.
The process is called sublimation
