HS BAND (Tape-typed Road Crack Repair Material)

Crack resistant bands are used for treatment of pavement surface layer cracks. Through special binder it is pasted on the crack resistant tape on sub-grades or surface cracks to form a high strength waterproof layer on the cracks, so that the pavement sub-grade cracks can not reflect upward, the water on the surface layer cannot penetration downward, thus to protect the surface layer and sub-grades stability.

Characteristics:

  1. Fastness adhesion.
  2. Good high-low temperature resistance.
  3. Special “self-healing” function. It could self-heal smaller puncture disrepair and smaller crack by filling.
  4. High strength of avulsion resistance, wear, no crack, no moving, no disrepair, stopping from extending of the crack.
  5. It could repair radioactive crack and forfication crack effectively.
  6. It is easy for using. Don’t need professional training. Need only two person construction.
  7. Fast construction with high efficiency.
  8. The construction is energy-conserving and environment-protective; No pollution and convenient.
  9. Low cost with high performance price ratio.
  10. Good construction effect. It forms lasting adhesion layer without sew avoiding water coming into the base layer crack because of its flexibility with low temperature.
  11. Wide range of applications:
    The product apply for both asphalt sub-grades and cement concrete pavement sub-grades, also apply to white to black, black to black, pavement sub-grade crack repair, bridge deck waterproofing and airport runway paving projects.

Ultra Thin Hot Mix asphalt

Saves fuel, saves time, saves trucks

What is Ultra-Thin Hot Mix?

Our state-of-the-art Ultra-Thin Hot Mix system combines the strength of hot mix with the flexibility of thin maintenance systems. This process combines a chip seal process with a hot mix process producing a single lift overlay that is significantly thinner (0.75 inch) than traditional hot mix asphalt applied at 1.5 inches thick.

Ultra-Thin Hot Mix is produced in a conventional hot mix plant using PG graded asphalt binders. These asphalt binders can be modified with polymer to meet traffic conditions. The hot mix is an open graded stone on stone matrix mix made with high quality, low polish aggregates that have to meet very strict gradation requirements. All of the components of the mix undergo extensive testing to ensure compliance with a specified mix design.

What are the benefits of Ultra-Thin Hot Mix?

The emergence of Ultra-Thin Hot Mix as a viable and economic addition to the road maintenance toolbox now allows local municipalities to reap the benefits that, until recently, had only been experienced on Interstate projects. In addition:

    • One of the most important advantages is the speed in which Ultra-Thin Hot Mix is applied and cools which allows for a minimal disruption to traffic.
    • The number of trucks required for the job is significantly reduced because of the thin mix and less tonnage of material required to cover an area.
    • Because the roadway need not be milled, additional trucks used for the removal and export of the millings to a storage area will not be needed.
    • The thin lift minimized static loading on bridge decks.
    • The application can be used on either an existing bituminous or Portland cement concrete pavement.
    • Because Ultra-Thin Hot Mix is an open-graded hot mix asphalt, water simply enters the mix and moves between the stone on stone matrix and above the Polymer-Modified Emulsion to storm water outlets and into storm drains.

What is the Ultra-Thin Hot Mix Process?

The hot mix is delivered by conventional dump trucks to a specialized lay-down machine.

    • In the one-pass process, a Polymer-Modified Emulsion is applied as a primer to the existing pavement by the lay-down machine.
    • The Polymer-Modified Emulsion, which acts as a waterproofing membrane and a bonding agent, is followed immediately by the application of the Ultra-Thin Hot Mix.
    • Compaction for the material is typically accomplished using a minimum of one or more steel wheel roller (10 ton minimum weight) operated in static mode.

Typically, unrestricted traffic can be returned to the fresh surface within one half hour. The Ultra-Thin Hot Mix process can be one of the most effective surface treatments for high volume, high speed roads such as interstates, where quick return to traffic is important. In addition, the thin lift eliminates the need for expensive safety alterations to guide rail, shoulders, bridge overpasses and signage.

EP COAT (Emulsified Asphalt)

EP-coat is an epoxy primer to increase the adhesion and water resistance of new and old asphalt, the steel plate deck, and concrete slab in the repairing of general asphalt and concrete pavement.

Properties of EP-coat

  • Increase adhesion between concrete slab and steel plate deck for bridge pavement
  • Self waterproof without waterproof layers
  • Increase adhesion of the boundary for old and new concrete/asphalt pavement repairing.
  • Excellent workability and easy quality control in mechanical construction

Applications of EP-coat

  • Pavement for new steel plate deck and concrete bridge
  • Repairing pavement of steel plate deck and concrete bridge
  • Pavement for heavy traffic roads and checkpoints
    • HSM Modifier
    • HSL-7001 (Cationic Emulsified Asphalt Modifier)
    • EPO-AS (Epoxy Asphalt Pavement)

What is EPO-AS?
