What are the big machines called that lay asphalt on main roads and highways?
The big machine that lays asphalt on main roads and highways is called a cold planer.
What is the difference between penetration and softening point of a bitumen?
The penetration point of Bitumens such as asphalt is the depth in tenths of millimeters a standard weighted needle will penetrate through a given sample of asphalt at a given time and temperature. The softening point of Bitumen such as asphalt is the temperature at which the Bitumen softens at standard conditions. Method of detrmination employs a ball and ring in which the ball falls through the ring after the softening has been reached.
What is the difference between hot asphalt and cold asphalt?
Hot mix asphalt is is heated for application, which thins the material. Remember those steaming metal buckets you used to see on industrial rooftops? Cold asphalt is liquified with something else besides heat. There are two kinds: Emulsified asphalt is mixed with water and an emulsifying agent. Think of it like salad dressing that does not separate in the bottle. The other kind is called Cutback asphalt and is mixed with a petroleum solvent such as naptha, gasoline, or kerosene. They both are liquids at ambient temperature when applied; then the solvent or water evaporates, leaving the asphalt behind. Look up at asphaltinstitute.org
What is hot mix asphalt?
The main asphalt paving product is hot mix asphalt, in which asphalt cement is used to bind a mixture of stone, sand, and gravel.
How much does liquid asphalt weigh per gallon?
Liquid asphalt has a specific gravity range from 0.98 to 1.02. Typically, a specific gravity of 1.0 is used. This can vary with the type of asphalt and the temperature of the asphalt. A specific gravity of 1.0 is the same as water measured at the reference temperature of 60 degrees Fahrenheit. This specific gravity of 1.0 corresponds to a density (or specific weight) of 1 gram per cubic centimeter (1 g/cm3) or 62.4 pounds per cubic foot (62.4 lb/ft3) or 8.34 pounds per gallon (8.34 lb/gal)
Why do you asphalt in the summer?
You can lay asphalt any season as long as the air and the ground temperature are in the proper range. below a certain temp it's a definite no-no.
Is it okay to lay new asphalt driveway with 40 deg temperature at night after laying it down?

What is the job of an asphalt contractor?
An asphalt contractor is hired by a general contractor to lay asphalt on any given job. They are often contracted for jobs involving roads or sometimes schools.
Is Asphalt a Newtonian fluid?
At high temperatures such as 275F (135C), asphalt is a Newtonian fluid. At low temperature, asphalt is a non-Newtonian fluid.

What are the big machines called that lay asphalt on main roads and highways?

What temperature is asphalt cement shipped at?
I usually load slow cure cutback asphalt cement between 70-75 degrees celsius for shipping.
How do you tile over asphalt?
There isn't a good way to tile over asphalt. Because of temperature changes, asphalt expands and contracts on a regular basis and this will cause the tile to crack. Also, tile will allow water to get through and cause a problem with freezing between the asphalt and the tiles.
What is the melting point of asphalt cement?
Asphalt cement is an amorphous polymer, which makes defining the melting point difficult. It's more common to refer to the glassy-transition temperature and the softening temperature. The glassy-transition temperature of asphalt cement is between -35 °C to -10 °C and the softening point ranges from 30 °C to 150 °C. While these temperatures vary for each asphalt, exact values an be determined with a DSC test and the ring and ball test respectfully.
