摘　　要：为了获得抗压强度和抗拉强度较优的沥青砂浆,采用单轴压缩试验和劈裂试验研究不同拌合温度、油石比与机制砂级配对沥青砂浆抗压强度、抗拉强度的影响,并通过均匀设计试验,得出以下结果:级配对沥青砂浆的抗压强度影响最大,拌合温度次之,油石比对沥青砂浆的抗压强度影响最小;级配对沥青砂浆的抗拉强度影响最大,油石比次之,拌合温度对沥青砂浆的抗拉强度影响最小。研究结果表明,机制砂级配是沥青砂浆控制的关键性因素。In order to obtain the asphalt mortar with excellent compressive strength and tensile strength,uniaxial compression test and splitting test were used to study the effects of mixing temperature,asphalt-aggregate ratio and gradation on the compressive strength and tensile strength of asphalt mortar.The results show that the gradation has the strongest influence on the compressive strength of asphalt mortar,followed by the mixing temperature,and asphalt-aggregate ratio has the least effect on the compressive strength of asphalt mortar.Gradation has the strongest influence on the tensile strength of asphalt mortar,followed by the asphalt-aggregate ratio,and mixing temperature has the least effect on the tensile strength of asphalt mortar.The results show that mixing temperature is a key factor for asphalt mortar.
