It is seen that the bitumen, which is the most important binding that causes the asphalt mixture

to adhere to the pavement, is effective on the mechanical properties of the microstructures such

as consistency-elastic. In addition, studies have been submitted in which various polymers are

added to improve bitumen, increase durability and improve mechanical properties. For this

reason, 50/70 penetration of pure bitumen was added to different ratios of polymers such as

polyester and rubber. The capacity and loss factor of pure and doped bitumen samples were

measured depending on temperature, frequency, and thickness. Dielectric constant, dielectric

energy loss and variable field conductivity were calculated from the measurement. Dielectric

responses were examined according to temperature, frequency, thickness, additive type and
