沥青及沥青砂浆盐冻性能的灰色关联熵分析
|
摘要
盐冻循环极易引起沥青路面出现早期破坏,影响行车质量,导致路面使用寿命降低。对基质沥青、SBS改性沥青和胶粉改性沥青盐冻循环前后的3个基本指标(针入度指数、当量软化点和延度)进行了测试;对经历不同盐冻循环的基质沥青砂浆、SBS改性沥青砂浆和胶粉改性沥青砂浆试件进行单轴压缩蠕变试验;采用灰色关联熵分析法对盐冻融循环前后影响沥青及沥青砂浆性能的各因素进行了分析。结果表明,盐冻循环各因素对沥青的基本指标有一定影响,但是沥青自身基本指标对沥青使用性能影响更大;盐冻循环对沥青砂浆的力学性能影响明显,其中融雪剂溶液浓度对沥青砂浆力学性能影响最大;因此,在昼夜温差大或者北方寒冷地区修建道路时,要严格控制沥青基本指标和融雪剂的使用量以减少对路面结构的损坏。
Salt freezing would cause asphalt pavement to premature failure easily,which would affect the quality of driving and lead to reduce the service life of road.The three routine indicators(penetration,equivalent softening point and ductility)of the matrix asphalt,SBS modified asphalt and rubber powder modified asphalt were tested before and after the salt freezing.Uniaxial compression creep test of three kinds of asphalt mortar specimens were conducted after different salt freezing cycles.The influence factors that would change the performance of the asphalt and asphalt mortar were analyzed through grey relation entropy analysis.The analysis results showed that salt freezing cycle would affect the basic indicators of asphalt.But the performance of the asphalt itself is more important than others.The salt freezing cycle would affect mechanics performance of the asphalt mortar greatly and the concentration of salt solution is the major factor.So it is necessary to control the basic indicators of asphalt strictly and the use of de-icing salt in cold area,in order to reduce the damage of pavement structure.
