  brittle point
     The tests show that after adding up fiber,the bending strain energy of asphalt concrete is improved,the brittle point temperature is decreased,the low temperature creep rate is increased,and the strain energy of J-integral is improved. The low temperature performance of fiber-enhanced asphalt concrete is better after added with fiber.

This paper elaborates the research on the ruptured characteristics of domestic heavy oil asphalt mixture at low temperature by means of constant loading speed bending test and split test. An evaluation of asphalt itself was made on the ruptured cracking performance at low termperature according to the indices referred to ultimate strength, ultimate tensile strain, ruptured stiffness modulus and brittle point of the mixture under various temperatures and various loading speeds. It is justified that its anti-cracking...

This paper elaborates the research on the ruptured characteristics of domestic heavy oil asphalt mixture at low temperature by means of constant loading speed bending test and split test. An evaluation of asphalt itself was made on the ruptured cracking performance at low termperature according to the indices referred to ultimate strength, ultimate tensile strain, ruptured stiffness modulus and brittle point of the mixture under various temperatures and various loading speeds. It is justified that its anti-cracking performance at low temperature has reached to or exceeded the imported asphalt level.
