摘　　要：利用J100-1型岩石直剪仪对含橡胶沥青碎石防水层的复合试件在不同条件下进行剪切试验,揭示防水层处抗剪强度与众多因素的关系。研究表明对水泥混凝土板表面进行刻槽,50﹟橡胶粉改性沥青洒布量为2.05kg/m2,碎石粒径为9.5~13.2mm,碎石洒布量以14.45kg/m2为宜。The shear test has been conducted on composite specimen with rubber asphalt macadam waterproof layer by direct shear apparatus J100- 1 type of rock. The relationship between shear strength and factors has been revealed in this paper. The study has shown that groove on the cement concrete slab surface、2. 05 per square of50 # rubber asphalt、gravel particle size changing from 9. 5 to 13. 2mm and 14. 45 kg per square in dosage are best to improve shear strength of waterproofing layer.
