Abstract
Styrenebutadienestyrene SBS modified bitumen crack filling material with organophilic montmorillonite OCFM was prepared by melt blending Xray diffraction analysis shows that the interlayer spacing of organophilic montmorillonite OMMT in OCFM is widened and an exfoliated structure may be formed Thermaloxidative aging behavior of OCFM and SBS modified bitumen crack filling material SCFM was investigated The experimental results indicate that the rate of thermaloxidative aging of OCFM is much slower than that of SCFM which can be attributed to barrier of exfoliated structure of OCFM to oxygen
