本文对沥青混合料疲劳试验进行了探讨,比较了不同的试验方式,介绍了根据比较结果试制的疲劳试验机,分析了连续加栽和不连续加栽的区别,进而对四种不同粘结料的沥青混合料试件进行了疲劳试验,得出了四种沥青混合料疲劳规律的经验回归公式,并结合野外试验路的实践进行了对照,说明设计试制的控制等挠度来间接给定固定回弹应变幅度的疲劳试验机是基本可行的。 In this paper, the fatigue test of asphalt mixture was discussed. Different test methods were compared. The fatigue testing machine prototyped on the basis of comparison results was introduced. The differences between continuous and discontinuous additions were analyzed. Four kinds of different binder materials Of the asphalt mixture specimens fatigue test, obtained four kinds of asphalt mixture fatigue law of empirical regression formula, combined with the practice of field test road were compared, indicating the design of the trial of control deflection to indirectly give a fixed back Elastic strain amplitude of the fatigue testing machine is basically feasible.
