Description

    FIELD OF THE INVENTION
  • The present invention relates to a construction method for preventing cracks after repair.
    • BACKGROUND OF THE INVENTION
  • Cracks occur on roads and bridges due to various reasons. If these cracks are not timely treated and sealingly repaired, after rainwater flows into the cracks, the roads and bridges will be damaged more quickly under pressure of fully-loaded vehicles. This shortens life cycle of the roads and bridges.
  • The cracks need to be sealingly repaired to prevent water from flowing into the cracks. Although various construction methods are available for sealing cracks, for example, pouring asphalt into the cracks, or coating asphalt on the crack surfaces, or adhering strip repairing material on the crack surfaces. All these methods can seal the cracks and prevent rainwater from flowing into the cracks. However, in the cases of pressure from loaded vehicles, weather changes, and crack expansion, the repairing materials such as the asphalt sealing the cracks tend to aged, break, crack, even separate from the cracks, and consequently water flows into the cracks, causing damages to the roads and bridges.
    • SUMMARY OF THE INVENTION
  • The objective of the present invention is to provide a crack seal repairing method capable of preventing cracking and separation of the repairing material.
  • The objective of the present invention is achieved by designing a construction method for sealingly repairing cracks on the road, capable of preventing cracking and separation of the repairing material.
      • a. coating a solvent capable of interfusing with asphalt and dust on cracks to improve the caking property between seal repairing materials and the cracks;
      • b. scattering high-intensity fibers with suitable length and size on the cracks, wherein longitudinal directions of most fibers are crossed with the trends of the cracks, and lapped with each other or form a reticular structure;
      • c. pouring asphalt or macromolecule glue into the cracks, or adhering strip repairing materials onto the cracks, wherein the fibers are bonded to the seal repairing material automatically, (finally scattering suitable sand on the seal repairing material).
  • In the construction method for preventing cracking after repair according to the present invention, the solvent coated on the cracks is capable of interfusing with loose dust and asphalt on the crack surfaces so that the seal repairing material is fully bonded to the crack surfaces, thereby preventing the seal repairing material from separating from the crack surfaces. In addition, the scattered high-intensity fibers are crossed with the trends of the cracks, and the seal repairing material is bonded to and interfused with the high-intensity fibers having properties of crack resistance, tension resistance, and pressure resistance, and form a flexible seal repairing layer having good expansibility, low-temperature cracking resistance, and crack prevention capabilities. In this way, the sealingly repaired cracks are prevented from cracking again.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The accompanying drawings are schematic diagrams of the present invention.
    •  DETAILED DESCRIPTION OF THE EMBODIMENTS
  • The following section further describes the present invention with reference to the specific embodiments.
  • A construction method for sealingly repairing cracks on the road capable of preventing cracking and separation of the repairing material includes the following steps:
      • a. coating a solvent 2 capable of interfusing with asphalt and dust on cracks 1 to improve the caking property between seal repairing materials and cracks;
      • b. scattering high-intensity fibers 3 with suitable length and size on the crack surfaces, wherein longitudinal directions of most fibers are crossed with the trends of the cracks, and lapped with each other or form a reticular structure;
      • c. pouring asphalt or macromolecule glue into the cracks, or adhering strip repairing materials onto the cracks (wherein the fibers are bonded to the seal repairing material automatically), and scattering suitable sand.
  • Step b may be performed reversely to step c. To be specific, asphalt or macromolecule glue is first poured into the cracks, or strip repairing materials are adhered onto the cracks, and then high-intensity fibers are scattered on the cracks.
  • All the materials used in the present invention are available in the market. These materials are mainly composed of asphalt reducing agent, reclaiming agent, glue, asphalt, fiber, resin, polyester, rubber, joint strip, sealing strip, and sand, and the product names vary with manufacturers. According to the construction method for preventing cracking after sealing repair illustrated in FIG. 1, a solvent 2 is coated on cracks 1, high-intensity fibers 3 capable of preventing cracks are scattered on the cracks, and then pouring asphalt or macromolecule glue, or adhering a strip seal repairing material 4 on the cracks.
  • The cracks commonly occur on highways, national and provincial roads, municipal roads, and runways.
  • The solvent is asphalt reducing agent, reclaiming agent, emulsified asphalt, glue, resin, or oil agent. The solvent coated on the cracks is capable of interfusing with loose dust and asphalt on the crack surfaces so that the seal repairing material is fully bonded to the crack surfaces, thereby preventing the seal repairing material from separating from the crack surfaces.
  • The high-intensity fibers are polymer synthetic fibers, glass fibers, or steel fibers, which have properties such as crack resistance, tension resistance, and pressure resistance, and can adhere to the solvent coated on the cracks.
  • The poured asphalt or macromolecule glue is asphalt, modified asphalt, silica-gel, or synthetic glue suitable for pouring; and the strip seal repairing materials are manufactured asphalt strips, water stop strips, or water-proof rolls.
  • The longitudinal directions of the fibers are crossed with the trends of the cracks, and lapped with each other to form a flexible expansion layer after the repairing material is interfused with the high-intensity fibers, thereby achieving an effect of low-temperature cracking resistance and crack prevention.
  • The sand is natural or mechanically manufactured common construction materials, such as, river sand, granite or basalt.
    • EXAMPLES
  • A construction method for sealingly repairing cracks on the road capable of preventing cracking and separation of the repairing material includes the following steps:
      • a. coating a solvent capable of interfusing with asphalt and dust on cracks, which are around 1 cm wide, to improve the caking property between seal repairing materials and cracks; the solvent is a mixture of oil and water, such as mixture of diesel oil, water and emulsified bitumen.
      • b. scattering high-intensity fibers, around 5 cm in dimensions of nylon textile fibers from the disposed tires, with suitable length and size on the crack surfaces, wherein longitudinal directions of most fibers are crossed with the trends of the cracks, and lapped with each other or form a reticular structure;
      • c. pouring asphalt or macromolecule glue, such as bitumen 70/100 or SBS modified asphalt, into the cracks, or adhering strip repairing materials onto the cracks (wherein the fibers are bonded to the seal repairing material automatically), and scattering suitable sand.
  • Step b may be performed reversely to step c. To be specific, asphalt or macromolecule glue is first poured into the cracks, or strip repairing materials are adhered onto the cracks, and then high-intensity fibers are scattered on the cracks.
