Kapejo company manufactures and supplies various types of lignin fibers and granular fibers for stone mastic asphalt (SMA), open-graded sliding layer (OGFC), asphalt concrete anti-slip layer hang, open-graded structure mixed materials and other high-performance asphalt pavement.

    Kapejo company to carry out road-building materials business for more than 20 years of history, in addition to cellulose material, the company also produces mineral fibers, polyester fibers, nylon fibers and polypropylene fibers and other products. Kapejo company also produces anti-alkaline fiber strengthened to achieve secondary roads, reducing concrete, shotcrete, stucco and mortar plastic shrinkage and cracking. By fiber-reinforced concrete production company after Kapejo higher impact strength and excellent anti-aging, wear tall and seepage performance.

    BoniFibers- road reinforcement material
    Since 1977, Kapejo BoniFibers company has a number of road construction projects in 10,000 is used to replace the asbestos fibers, which can effectively prevent the material pits, cracks and ruts generation, thus making bridges and roads more durable.

    Since 1977, BoniFibers large number of proven for the following areas is a cost-effective measures, such as:
    Asphalt pavement to prevent a "cracking, potholes and ruts."
    Asphalt and concrete pavement cracks filled letters.
    "Pits filled."
    For the deck layer to prevent the influence of water on the structural member.

    For curbs, curbs ensure vertical position, crash and surface reflux.

    BoniFibers B and BoniFibers C is one hundred percent polyester. They are extracted from the polymerization of petroleum products, petroleum products and bitumen component is, therefore, between BoniFibers and it strengthens the asphalt, there is a very nice fit. BoniFibers not shrink at temperatures below 480 ℃ (250 ℉), the deformation or softening, and will not lose their strength, and can retain its flexibility at 40 ℉ (-40 ℃) time.

    Strengthening hot mix asphalt with BoniFiber B
    Hot mix asphalt (HMA) added BoniFibers B can prevent reflective cracking, cracks or pits low production, but also to prevent pavement stripping, pushing, and the formation of ruts.

    Mix of asphalt and BoniFibers
    First, in accordance with the general standards, the mix of aggregate and asphalt binder, adding BoniFibers B, the optimum amount of asphalt will be increased, but not more than 0.3%. Another design should ensure that the porosity of not less than 3%. To ensure that the mix of slip resistance.

    Secondly, for different traffic density, the addition amount BoniFibers B are different. When the traffic density is less than 3,000 vehicles / day ,, and minimum road truck traffic flow, fiber amount of 0.125% (of the total mixed material), road traffic density of more than 8,000 vehicles / day, adding 0.375%, traffic density between 3,000 and about 8,000 vehicles / day on the road, adding 0.25%. In addition, when determining the actual amount BoniFibers B should also consider the life cycle cost factor.

    Preparation of hot mix asphalt
    BoniFibers enhanced with hot mix asphalt (HMA) the mixing temperature with conventional hot mix asphalt mixing temperature of the same (typically 150 ℃). Any mix in the wind when laying will soon cool down, especially for asphalt structural layer thinner. In addition, when the colder nighttime construction, due to radiation sake lose more heat. Therefore, in the above case, the mixture ratio of the factory temperature should ideally the construction temperature is higher. As good temperature stability BoniFibers B, upon BoniFiber strengthened, can produce top quality hot mix asphalt.

    For drum mixer, BoniFibers before adding the asphalt binder, can automatically load transported by the blast added to the mixing vessel and the dry mixing mineral aggregate. For batch mixing machine, you can use the same weighing and conveying systems. If there is no blower, BoniFibers B mixing vessel capacity can be added to the size of fiber bags. The unopened bags of fiber added to the mixing vessel and mineral aggregate dry mix. For batch mixing machine, BoniFibers B and mineral aggregate dry mix time should not be less than 15 seconds, and the wet mix and dry mixing time a total of not more than 60 seconds.

    Kapejo company believes his road enhancement products are world class. Over the years, Kapejo has been a road materials business partner, today and you would like to cooperate sincerely partnering.

    Kapejo BoniFibers production company are widely used in the United States from the desert heat to low temperatures below freezing all kinds of environments. Since 1977, BoniFibers has been used in more than 12,000 projects in the asphalt.
