    Abstract
  • The basic properties of FYT waterproof were analyzed.Its specific technical indices were measured.Its optimum amount and optimum dosage range were determined by shear test and pullout test in laboratory.The influences of temperature, interfacial roughness and water on the pavement performance of FYT waterproof were studied systematically.Comparison test analysis for FYT waterproof and the others used in common were carried out.Analysis result shows that optimum spreading volume for FYT-1# is 1.4~1.5 kg·m-2, and that for FYT-2# is 0.10~0.15 kg·m-2.The shear strength and tensile strength of FYT at 25 ℃ is 7~2times of that at 60 ℃.The losses of shear strength and tensile strength of FYT are respectively 3.0% and 7.5% after soaking in water.Comparing with other waterproofs, except for synchronous crushed stone, its shear strength and tensile strength are 3~4 times of that of the others.Obviously, FYT has good pavement performance.
