AtypeofAl³⁺modifiedBoneGlue(BG)wasusedasmodifiertopreparethenewBone Glue(Al-BG)modified asphalt.The rheological properties of new bone glue modifiedasphalt were investigated using Brookfield rotational viscosity test， DynamicS hear R he o-logical(DSR) test and Bending Beam Rheological(BBR) test.The results of the researchshow that new bone glue can increase the viscosity of the original asphalt， and enhance theelastic recovery capability of the original asphalt under the action of the load.The increaseof complex modulus and the decrease of phase angle indicate that new bone glue can improveanti-shear deformation ability of the original asphalt at high temperatures.When the con-tent of new bone glue is 7.5%， the improvement of the rheological properties of the originalasphalt is the best.
