Embodiment 1

[0026] Add 8 parts of active compatibilizer at room temperature into the reactor, and then add 100 parts of No. 90 road asphalt (brand: Shell) into the reactor; place the reactor in an oil bath at 130-150°C for heating, Use electromagnetic stirrer for stirring and dispersion, stirring speed 60r / min. Gradually add 10 parts of ammonia-free natural concentrated rubber latex (origin: Yunnan Hekou) (quality, the same below). The amount added should ensure that there is no overflow during the mixing process. After all the ammonia-free natural concentrated rubber latex is added, if the bubbles are reduced, it should be increased appropriately Stir the speed and stir until the mixture is uniform and without bubbles; prepare the B component for use.

[0027] Mix 100 parts of curing agent (Jiangsu) and 1.5 parts of curing accelerator at room temperature, and then place them in an oil bath at 120-140°C to heat to a constant temperature. After stirring, the component C is prepared at a const...

Embodiment 2

[0031] Add 10 parts of active compatibilizer at room temperature into the reactor, and then add 100 parts of No. 70 road asphalt (brand: Shell) into the reactor; place the reactor in an oil bath at 130-160°C for heating, Use electromagnetic stirrer for stirring and dispersion, stirring speed 60r / min. Then gradually add 5 parts of ammonia-free natural concentrated rubber latex (origin: Yunnan Hekou) (quality, the same below). The amount added should ensure that there is no overflow during the mixing process. After all the ammonia-free natural concentrated rubber latex is added, if the bubbles are reduced, it should be increased appropriately Stir the speed and stir until the mixture is uniform and without bubbles; prepare the B component for use.

[0032] Mix 100 parts of curing agent (Jiangsu) and 1.0 part of curing accelerator at room temperature, and then place them in an oil bath at 120-150℃ to heat to a constant temperature. After stirring, the component C is prepared at a co...

Embodiment 3

[0036] Add 8 parts of active compatibilizer at room temperature into the reactor, and then add 100 parts of No.110 road petroleum pitch (brand: Shell) into the reactor; place the reactor in an oil bath at 130-140℃ for heating, Use electromagnetic stirrer for stirring and dispersion, stirring speed 60r / min. Gradually add 20 parts of ammonia-free natural concentrated rubber latex (origin: Yunnan Hekou) (quality, the same below). The amount added should ensure that there is no overflow during the mixing process. After all the ammonia-free natural concentrated rubber latex is added, if the bubbles are reduced, it should be increased appropriately Stir the speed and stir until the mixture is uniform and without bubbles; prepare the B component for use.

[0037] Mix 100 parts of curing agent (Jiangsu) and 2.0 parts of curing accelerator at room temperature, and then place them in an oil bath at 120-130°C to heat to a constant temperature. After stirring, the component C is prepared at ...

Abstract

The invention discloses high-strength toughened rapid-curing chemically modified resin asphalt for permeable pavements and a preparation method of the asphalt. The asphalt is composed of three components A, B and C. The component A is epoxy resin; the component B consists of 100 parts of road petroleum asphalt, 3 to 20 parts of natural rubber and 3 to 15 parts of an active compatibilizer; and thecomponent C consists of 100 parts of a curing agent and 0.5 to 2.5 parts of a curing accelerator, wherein the mass ratio of the component A to the component B is (10-30):100, and the mass ratio of thecomponent A to the component C is 100:(50-200). The resin asphalt disclosed by the invention has the advantages of high strength, good toughness and flexibility, high curing speed, long service life,good durability and the like; the component A and the component B are separately stored and are good in stability; and construction and application are convenient. The resin asphalt is suitable for various pavements as a binder of a water-permeable anti-skid surface layer, not only can improve skid resistance of pavements, reduce noise, prolong the service life of the pavements and the like, butalso can play a role in constructing a sponge city, and thus has wide application prospects.

Description

Technical field [0001] The invention relates to the technical field of asphalt and a preparation method thereof, in particular to a high-strength toughening fast-curing chemically modified resin asphalt for permeable pavement and a preparation method thereof. Background technique [0002] With economic development and increasing demands for driving safety and comfort, the requirements for road anti-skid and reduction of driving noise are becoming more and more urgent. As a solution for the sponge city, permeable pavement has the functions of reducing noise, improving anti-skid performance, reducing water fog and water drift in rainy days, and can greatly improve driving safety. However, even if the high-viscosity physically modified asphalt is used, the water damage caused by insufficient cohesive force during use and the early diseases such as shifting are more prominent. [0003] Epoxy asphalt changes from thermoplasticity to thermosetting properties after curing. It has irrever...
