Description
Technical field
The utility model belongs to pavement cracks maintenance technique field, specifically, relates to a kind of asphalt overlay anti-splitting paster.
Background technology
The asphalt highway structure of China Higher level adopts semi-rigid type base usually, and the reflection crack of this basic unit is one of Major Diseases of flexible pavement.Reflection crack is there is in order to prevent the asphalt surface course of flexible pavement (or being called asphalt overlay), when new highway, between semi-rigid type base and asphalt surface course, laying anticracking material in advance, is one of technical way effectively suppressing crack upwards to be transmitted.In addition, the cement concrete pavement built in early days due to China has progressed into the medium-capital overhauling stage, a large amount of cement concrete pavements need to carry out white change black, old cement surface layer needs equally lay anticracking material, with the damage suppressing the reflection crack of old cement surface layer to cause the asphalt overlay be laid on the old surface layer of cement.Therefore, in the process of highway pavement construction and maintenance, the application of interlayer anticracking material widely.
In recent years, along with the innovation of material, be applied to more and more in the interlayer of asphalt pavement structure based on the anticracking material of the composite construction of high molecular polymer anti-splitting paster, achieve good suppression reflection crack upwards transmit, prevent moisture under the effect of oozing.High molecular polymer anti-splitting paster is made up of pitch, high molecular polymer, tire base, high-strength high temperature-resistant fabric, separation layer etc., and through the cracking resistance with tack of special web apparatus extrusion cladding and waterproofing materials.The geosynthetics that highway uses, stress absorption layer material etc. combine by this material, are the optimizing products of current asphalt overlay cracking resistance and waterproofing materials.
Fig. 1 shows the structural representation of traditional high molecular polymer anti-splitting paster.With reference to Fig. 1, traditional high molecular polymer anti-splitting paster 1000 is made up of high strength fabric layer 1100, first polymer modified asphalt layer 1200, low intensive tire basic unit 1600, second polymer modified asphalt layer 1300 and lower separation layer 1500 from top to bottom successively.Fig. 2 shows the schematic diagram that high molecular polymer anti-splitting paster is applied in the action principle of the interlayer of asphalt pavement structure.With reference to Fig. 2, action principle when high molecular polymer anti-splitting paster is applied in flexible pavement 200 is as follows: when semi-rigid type base or old cement surface layer generation drying shrinkage or warm plastic forming, the cracking degree at crack place originally can expand, due to soffit (i.e. the second polymer modified asphalt layer 1300) and the semi-rigid type base of anti-splitting paster 1000 or the well-bonded of old cement surface layer, make to create larger extensional at crack place, and stress relaxation will be there is gradually because of its viscous-elastic behaviour in the second polymer modified asphalt layer 1200; The upper surface (i.e. high strength fabric layer 1100) bonding with asphalt overlay of anti-splitting paster 1000 makes it deformation to occur because it has higher intensity, this just makes asphalt overlay to produce crack, and the reflection crack that semi-rigid type base or old cement surface layer produce stop by anti-splitting paster.
When constructing to high molecular polymer anti-splitting paster, first throwing off lower separation layer 1500, anti-splitting paster 1000 being aimed at and is pasted on the seam areas of the old surface layer of cement or the location of cracks of semi-rigid type base, then asphalt overlay.Because when paving, asphalt overlay has the high temperature of 120 DEG C ~ 170 DEG C, so the first polymer modified asphalt layer 1200 can by high temperature melting, and ooze out from the gap of high strength fabric layer 1100, soak into whole tissue layer 1100, the surface of tissue layer 1100 is covered by polymer modified asphalt, thus defines good interlaminar bonding effect with asphalt overlay.
But, because high strength fabric layer has different cloth textured and gaps, polymer modified asphalt has different temperature flowing, makes to cause polymer modified asphalt can not soak into the surface of high strength fabric layer completely when asphalt overlay because laying the fluctuation of temperature.Once the surface of high strength fabric layer can not soak into by polymer modified asphalt, so old cement surface layer or the anti-splitting paster interlayer of slip can be formed between semi-rigid type base and asphalt overlay, have a strong impact on the globality of asphalt pavement structure, thus cause the appearance of pavement disease.
