Embodiment Construction
[0015] The product raw material and weight ratio are: waste rubber powder 69-75, waste fiber adopts waste tire fiber or waste acrylic fiber 4-8, reinforcing agent adopts light calcium carbonate or carbon black 18-22, polyoctene rubber (dimensional other linking agent) 0.5-1.5, styrene-butadiene-styrene block copolymer 4-6, asphalt 25-31.
[0016] Put the above raw materials into a reaction kettle with a stirring device in proportion by weight, stir at a high speed for 15-20 minutes at a temperature of 170-200°C, then react with each other at a constant temperature of 190°C, and stir after 2 hours to form a loose Waste fiber asphalt mixture.

The invention relates to an asphalt mixing material with the waste fiber in traffic bridge circuit project and its producing method. The product formula comprises: waste rubber powder, waste fiber, reinforced agent 18-22, octane rubber 0.5-1.5, styrene -butadiene -styrene block copolymer 4-6 and asphalt 25-31. The preparing craft is that adding the materials into the pressure pan with the stirring apparatus to highly stir them at 180-220 deg., doing inter-reaction at the constant temperature and stirring them into loosing waste fiber asphalt mixing material.
Description
technical field [0001] The invention relates to a material for paving roads in road and bridge engineering, in particular to an asphalt mixture mixed with waste fibers and a production method thereof. Background technique [0002] With the rapid development of economic construction, modern transportation has put forward higher and higher requirements for the quality of asphalt pavement construction. The cracking of the pavement and the excessive driving noise and other diseases make the traditional asphalt mixture technology sometimes unable to meet the requirements of engineering construction. , more and more new materials are entering the field of asphalt pavement technology. Among them, fiber, as a special additive material, has been widely used in asphalt pavement engineering, and the fibers commonly used are mainly lignin fiber, polyacrylonitrile fiber, polyester fiber, etc. In asphalt concrete, it plays the role of adsorption, stabilization, reinforcement, dispersion ...
