Research on crack resistance evaluation of asphalt mixture at low temperature

In order to improve the low temperature evaluation, on the basis of the low temperature bending test unit volume destruction to evaluate the low temperature crack resistance of asphalt mixtures. Since the destruction can be indicators of unit volume mixture critical flexural tensile strain and flexural strength of two indicators integrated. Therefore, use it to assess the low temperature crack resistance of asphalt mixture is more scientific, the indicators has also become a new method of low-temperature research areas.
