1. Introduction

l An instrument used to study the entire development process of reflection cracks in asphalt mixtures at low temperatures, from cracking to failure, can truly simulate the occurrence and development of asphalt pavement and reflection cracks under periodic changes in weather and temperature.

l The test sample is 150mm long, 75mm wide, and 12-50mm high.

l Triangular waves are used for continuous loading, alternating stretching and compression are performed on the samples to simulate the movement of the pavement wearing layer with the movement of the broken rigid material below. When the test reaches the termination condition, the operation automatically stops.

l According to the testing standard ASTM WK26816
