Uniaxial compressive stress-strain curves of several groups basalt fiber crumb rubber mortars (BF-CRM) with different contents are tested. By comparing the GZH model, improved values parameters BF-CRM constitutive model based on obtained. Then, taking supporting scheme main substation mine as background, using FLAC3D to simulate roadway support, replace ordinary in original and combining triaxi...

This study investigated the effects of swelling-degradation degree on rheological properties and thermal pyrolysis behaviors crumb rubber modified bitumen (CRMB). The equilibrium viscosity CRMB in 160 °C-swelling process is 10.5 Pa·s at 8 h. During 200℃-degradation procedure, increased to a maximum value 20.58 7.5 h gradually reduced stable 11.09 after 35 swelling degradation processes exhibit ...
