Preparation and Evaluation of Trackless Emulsified Asphalt
On the basis of analyzing the action mechanism of trackless emulsified asphalt,this paper car-ried out the research on the preparation of trackless emulsified asphalt.Through the composite modification of hard asphalt particles and high melting point alkane polymer,the influence of its content on the performance of asphalt was studied,and the recommended formula of trackless modified asphalt was formed.The non-stick tire time tester was used to evaluate the stick wheel effect of different asphalt,Finally,high performance emul-sifier was selected for emulsification research,and the adhesive property of the final product was analyzed by adhesive pull out test and pendulum shear test.Under 25 ℃,the tensile strength of adhesion can reach 1.5 MPa,and the shear energy density can reach 0.21 J/cm2,and it has been successfully applied in expressway maintenance project.
