沥青砂浆的单轴拉伸蠕变特性

根据大量单轴拉伸蠕变试验数据，论证和比较沥青砂浆材料的蠕变规律。并应用非线性回归分析得到该材料受单轴恒定荷载下的应力应变关系，可较好地符合粘弹性四元流体模型（即伯格斯模型）和指数模型。从而为解决实际工程问题提供了基本的单轴拉伸蠕变特性。

The Simple Tension Creep Behaviors of Asphalt Mortar

Based on the experimental data from simple tension creep test, a creep law of asphalt mortar matzrial is testified and compared. The relationship of stress versus strain of this asphalt mortar under the constant tension load is obtained using the non linear regression analysis, which is well in coincidence with the viscoelastic four parameter liquid model and exponent model.Whereby providing a theoretical basis for solving the practical problems in simple tension creep.
