Dowel bars are generally provided across longitudinal joints of rigid pavement. The migration of asphalt cement to the surface of the pavement under wheel loads especially at high temperatures is called stripping. The lower the penetration of asphalt binder, the softer the asphalt binder.

Question
Identify the following statement whether it is (True) or (False). If your
answer is false, give the correct answer?
1- Dowel bars are generally provided across longitudinal joints of rigid
pavement.
2- The migration of asphalt cement to the surface of the pavement under
wheel loads especially at high temperatures is called stripping.
3- The lower the penetration of asphalt binder, the softer the asphalt binder.
4- We need to keep the aggregate for 24 hours in an oven at 105°C to obtain
the aggregate dry weight.
5- It is important to design thicker layers of asphalt if the subgrade materials
are not strong enough to withstand expected loads during their life cycle.
6- The medium curing asphalt is produced by blending asphalt with diesel
oil.
