The Effect of Modified Styrene Butadiene Rubber Latex on the Properties of Emulsified Asphalt and Mixture
In order to study the effect of styrene butadiene rubber (SBR) latex at various dosages on the properties of emulsified asphalt and its mixtures as well as to reveal SBR’s modification mechanism and action, the conventional test, dynamic shear rheology test, fluorescence microscopy test, infrared spectroscopy test, contact angle test, wet wheel abrasion test and rutting deformation test were carried out to investigate the conventional properties, rheological properties, microphase structure, adhesive properties and the abrasion resistance of its mixtures, the resistance to water damage and rutting resistance of the modified SBR emulsified asphalt. The results show that SBR can make a significant improvement in ductility and softening point of emulsified asphalt with reduction in emulsified asphalt’s penetration. SBR emulsified asphalt complex shear modulus and rutting factor increases and the phase angle decreases with the dosage of SBR The spatial structure of SBR can be stabilized in the emulsified asphalt, the linear correlation coefficients between the SBR doping and its area share were found to be high by binarized fluorescence microscopy image analysis. The SBR can make improvement in the contact angle for emulsified asphalt and in free energy on emulsified asphalt’s surface. The physical modification between SBR and emulsified asphalt. And SBR features excellent road properties, such as abrasion resistance, water damage resistance and rutting resistance.
