摘要
针对水泥混凝土＋沥青混凝土路面的层间粘接不良问题，研制了一种改性焦油沥青粘层，并对它的剪切强度、抗拉强度和水泥混凝土（钢板）—沥青混凝土层间粘接强度进行了测定。结果表明，采用改性焦油沥青粘层，可大幅度地提高层间粘接强度。
A modified coal tar had been prepared and its shearing strength,tensile strength,adhering strength to cement concrete and asphalt concrete have been measured,when is it used as adhesive agent.
