the other is more popular in United Kingdom. Ans✔✔✔-False
The distillation process of crude petroleum produces many products, including
the following except _________
Asphalt
Diesel
Gasoline
Tar
Kerosene Ans✔✔✔-Tar
The advantage of asphalt cutback and asphalt emulsion is the convenience in
application: they are liquid form at room temperature while asphalt cement has
to be heated to become liquid. Ans✔✔✔-True
Asphalt emulsion is made of the following, except _____________
Water
Emulsifying agent
Diesel
,Asphalt cement Ans✔✔✔-Diesel
Although emulsions and cutbacks can be used for the same applications, the use
of emulsions is increasing, because the following reasons except ___________
Cutbacks release environmentally unacceptable hydrocarbons into the
atmosphere
