Ultrasonic testing can be used for a nondestructive and rapid determination of material properties. In this study, twelve asphalt mixture samples four different types were fabricated in conventional property tests two ultrasonic wave tests. Physical properties such as bulk specific gravity air void content, mechanical dynamic modulus phase angle, acoustic velocity measured. Relationships betwee...
Background and Objective: The quality of flat breads depends in part on the textural and structural properties of breads during storage. These properties are largely affected by flour quality. This research aimed at evaluating textural and structural properties of Lavash bread types during storage by different techniques, comparing these methods and determination of correlation between their re...
