由于沥青混凝土材料强度的温度依赖性，弯沉以至路面结构承载能力都随温度而变化。
Since asphaltic concrete materials are temperature dependent in nature, measured deflections and hence the structural capacity of pavement vary with temperature.
通过分析研究，提出了评价刚性路面结构承载能力方法和指标，对刚性路面使用性能评定有较好指导作用。
By analyzing and researching, the paper proposed the method and index of evaluating on rigid pavement structure load capacity for reference.
SAF应力吸收层系统具有良好的抗反射裂缝能力，混合料密实、透水性小，可以减少路面水损坏的产生，用该结构可以有效解决旧路加铺时反射裂缝的产生。
SAF stress absorbing layer has very good ability to resist reflective cracks. Because of its air-free and little water permeability, it can decrease the damage caused by water in the pavement.
