摘要:
为确定沥青混合料的粘弹性参数,在10,5,0,-5,-15,-20,-25,-30 ℃下进行了应力松弛试验,采有Maxwell摸型,运用粘弹性力学相关理论对沥青混合料的粘弹性参数测定方法进行了分析,提出了该测定方法的数学模型,并用Origin软件进行了计算求解.分析指出,用累计耗散能可分析沥青混合料的疲劳破坏,累计耗散能与疲劳寿命之间存在唯一的关系,其它因素如试验方法、加载频率、加载模式、温度等对其影响不大.最后简要说明了累积耗散能的求解方法.
Abstract:
In order to determine the viscoelastic parameters of asphalt mixture, stress relaxation test was carried out at 10,5,0,-5,-15,-20,-25,-30 °C. The analysis points out that the fatigue failure of asphalt mixture can be analyzed with the cumulative dissipative energy, and there is a unique relationship between the cumulative dissipative energy and the fatigue life, and other factors such as test method, loading frequency, loading mode, temperature, etc. have little effect on it. Finally, the solution method of cumulative dissipated energy is briefly described.
