The existed material fatigue performance test curves are dealt with and analyzed, and the non - dimensional stress - strain curve, tangent modulus factor curve and fatigue life curve are drawn based on the experiment data, and these three non - dimensional parameter curves are used to find the inherent rules that the test curves can be replaced each other to some extent. it can be concluded that if the common character and system error of these materials are found, the test curve of a certain material can be used for reference by another material. this is a simple approach about fatigue life estimate and is engineering practical

The static triaxial test of two engineerings shows that the breaking strength of asphalt concrete declines significantly as the temperature rises and the strain increases noticeably when breaking. increase in the asphalt content leads to decrease in tangent modulus and cohesion, but the internal friction angle tends to increase. increasing confining stress results in the augment of the maximum stress and the ultimate value of volumetric strain
兩個實際工程的靜三軸變形與強度試驗表明，隨著溫度升高瀝青混凝土破壞強度明顯降低，破壞時應變明顯加大；瀝青含量的增加會導致切線模量和凝聚力降低，但內摩擦角趨于增加；周圍壓力增大會導致最大應力_ d增大，其體變壓縮極限值也越大。 -
If asphalt concrete specimen is in stabilization by exert confining stress before the static triaxial test, it is then found that under the condition that time is long enough, the volume of the specimen will shorten gradually and stable around a fixed value, and the amount of compression is essentially the half of the volume of void itself. it is also found that in stabilization by exert confining stress the linear phrase will be shorten in the figure of the static triaxial test of specimen, while the initial tangent modulus will be augment. 3
