摘要:

通过自制的抗剪试验卡具,在设定的剪切温度条件下,以一定的剪切速率进行抗剪强度试验,对比改性沥青、改性乳化沥青、乳化沥青、粘层油乳化沥青4种不同沥青粘结层的抗剪强度,比较水泥混凝土、水泥稳定碎石、石灰粉煤灰稳定碎石3种常用基底材料对粘结层抗剪强度的影响,结果表明:基底材料强度越高,粘结材料用量适当,层间粘结效果就越好.结合造价节省和施工方便的因素,推荐在高速公路中优先采用乳化沥青下封层.

Abstract:

Through the self-made shear test fixture, under the set shear temperature conditions, the shear strength test was carried out at a certain shear rate, and the shear strength of four different asphalt bonding layers of modified asphalt, modified emulsified asphalt, emulsified asphalt and viscous oil emulsified asphalt were compared, and the influence of three commonly used substrate materials on the shear strength of the bonding layer was compared with the three commonly used substrate materials of cement concrete, cement stabilized crushed stone and lime fly ash stabilized crushed stone, and the results showed that the higher the strength of the substrate material, the better the bonding effect between the layers. Combined with the factors of cost saving and convenient construction, it is recommended to give priority to the use of emulsified asphalt lower sealing layer in expressways.
