The invention discloses a wheel-sticking-free emulsified
asphalt, a preparing method, a construction technology and application of the wheel-sticking-free emulsified
asphalt. The wheel-sticking-free emulsified
asphalt is prepared from, by
mass, 10-50% of matrix asphalt, 10-50% of hard asphalt, 0-5% of a
polymer modifier, 0.3-3% of an asphalt emulsifier, 0-1% of a
thickening agent and the balance an acid-base regulating agent and water to reach 100%. The preparing method comprises the steps that firstly, the
polymer modifier, the asphalt emulsifier and the
thickening agent are added into water, the pH value is regulated, and a
soap solution is prepared; then, the matrix asphalt is heated to 150 DEG C, the hard asphalt is heated to 160 DEG C, the matrix asphalt and the hard asphalt are stirred evenly in a stirring state, the obtained mixed asphalt and the
soap solution are subjected to high-speed shearing with a
colloid mill together, and the emulsified asphalt is obtained, wherein the emulsifying process is simple and practical. The emulsified asphalt has the effect of being free of wheel sticking when serving as road tack coat oil, tack coats are prevented from being damaged by construction equipment or transportation vehicles, the construction efficiency is improved, and the effect of preventing environment
pollution is also achieved.
