Influence of Salt Freezing on Asphalt Mortar's Stiffness Modulus
In winter of the northern region, de-icing salt is used when the pavement is covered with snow. However, the use of de-icing salt affects the performance of the pavement materials greatly. The stiffness modulus is an important indicator of asphalt mortar's performance. So the stiffness modulus is selected as the research object. Uniaxial compression creep experiments of salt freezing asphalt mortar upon three different stresses were conducted. The corresponding creep curves were acquired. Stiffness modulus curves could be drawn from the ratio of stress and strain. The varying laws of asphalt mortar's stiffness modulus under various uniaxial stresses and salt freezing conditions could be concluded. The results show that with increasing salt concentration, the stiffness modulus of asphalt mortar decreases significantly.
