Mobility caused by same-action is destroyed and canalized traffic is on the rise, and bituminous pavement a large amount of track occurs, gathers around packet and cracking
Equal breakoff phenomenons.The Rutting damage of bituminous pavement makes road surface excessive deformation, influences surface evenness, has slackened surface layer and road surface is whole
The intensity of body structure, and then induce other pavement diseases.The absolute viscosity of pitch is greater than when high-viscosity modified asphalt refers to 60 DEG C
The modified pitch of 20000Pas, because it with preferable high-temperature stability, low-temperature cracking-resistance, inoxidizability and good is applied
Work workability is widely used in multi-porous permeable type bituminous pavement (OGFC) and the road surface stone matrix asphalt mixture (SMA).It is long
Phase practice have shown that, the intensity of asphalt under 60 DEG C of dynamic viscosities of asphalt material and summer bituminous pavement maximum temperature,
Rutting resistance has good correlation.During the broiling summer under high temperature, pitch possesses higher viscosity, then asphalt
Intensity just will increase, and the plastic flow deformation or shear-deformable small generated under wheel load effect, Rut resistance etc. permanently damages
Harmful ability just enhances.

Using polyphosphoric acids, higher aliphatic, aromatic naphtha, rubber, dispersing agent, silane coupling agent, the disadvantage is that only leaning on polyphosphoric acids and base
Chemical action between matter pitch is unable to reach the highly viscous requirement of drainage pavement, and low-temperature cracking-resistance not can guarantee, and
Single alkyl phosphonic acid ester conversion rate is not high in the alkyl phosphate of generation, this is the limitation of higher aliphatic.
Currently, asphaltum with high viscosity is mainly prepared by adding high molecular polymer modification in asphalt, add
High molecular polymer can obviously improve the high and low temperature performance of pitch, improve high temperature Rut resistance, the low temperature cracking resistance energy of bituminous pavement
Power.But since there are the differences such as molecular weight, density, viscosity for most of high molecular materials and pitch, make polymer in pitch point
Difficulty is dissipated, cannot be fully compatible with pitch, leading to modified pitch system, storage stability is bad at high temperature, is easy layering, shadow
Ring the service life of modified pitch quality and normal construction and bituminous pavement；The viscosity of asphaltum with high viscosity is excessive simultaneously, causes to apply
It the problem of work workability, also can not be ignored.
