Study of Fracture Properties of Cement Stabilized Macadam

  •  Yinpeng Zhang    


By means of three-point bending method, the fracture toughness and fracture energy of cement stabilized macadam were measured respectively. The test results indicate that, with the increase of curing period, the fracture toughness and the fracture energy are increasing gradually. As the increase of cement content, the peak vertical load and fracture toughness of the specimen is increasing gradually, however, the fracture energy is decreasing gradually.
