Dielectric properties of asphalt materials

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 ratio.
