Embodiment 1

[0048] Example 1, a colored permeable asphalt, the raw material components are shown in Table 1 by mass percentage. The colored permeable asphalt is prepared through the following steps:

[0049] Step 1, heat the coarse and fine aggregates to 190°C and add them into the mixing tank, then put in the anti-rutting agent (KZD-I-K) and polyester fiber (Yancheng Baosilong Engineering Fiber Technology Co., Ltd., 6mm) , stirring for 10s, each material is evenly mixed in the mixing tank and the mixing tank is preheated;

[0050] Step 2: Add high-viscosity agent (Shenzhen Haichuan New Material Technology Co., Ltd., SINOTPS) and decolorized asphalt (Foshan Fangxiang Chemical Co., Ltd., 0# hydrogenated petroleum resin) heated to 175°C in the mixing tank, and continue mixing 70s;

[0051] Step 3, add cement (42.5R Portland cement) and red iron oxide into the mixing tank, and mix for 130s;

[0052] Step 4, discharge.

[0053] Among them, the coarse aggregate is clean, dry, and rough-sur...

Embodiment 2

[0055] Embodiment 2 is different from Embodiment 1 in that, by mass percentage, the raw material components are as shown in Table 1.

Embodiment 3

[0056] Embodiment 3 differs from Embodiment 1 in that, by mass percentage, the raw material components are as shown in Table 1.

Abstract

The invention discloses colored porous asphalt, and belongs to the field of municipal roads. Raw materials of the colored porous asphalt comprise the following components of, in percentage by mass, 4.5-6% of discolored asphalt, 80-82% of coarse aggregate, 8-9% of fine aggregate, 1.5-2% of inorganic toner, 0.8-1.1% of cement, and the balance auxiliaries. The colored porous asphalt has the followingadvantages that through cooperation of the coarse aggregate and the fine aggregate which are used as aggregate of asphalt, gaps among the coarse aggregate are filled by the fine aggregate, so that the stability of the asphalt is effectively improved; meanwhile, gaps among the fine aggregate can be filled by the inorganic toner, so that the stability of the asphalt is further improved; after wateris added, cement can be subjected to hardening, and can firmly cement the asphalt, the coarse aggregate, the fine aggregate, the inorganic toner and the auxiliaries, so that the stability of an asphalt system is further improved; in a mixing stage, in a stirring process, the cement can diffuse into gaps among the coarse aggregate and the fine aggregate, and plays a part in filling, and in a laying process, the cement can be subjected to cementation and hardening during watering maintenance, so that the stability and the anti-rut capability of the asphalt system are improved.

Description

technical field [0001] The invention relates to the field of municipal roads, in particular to a colored permeable asphalt and a preparation method thereof. Background technique [0002] Colored asphalt mainly refers to the asphalt mixture with added pigments, which is the asphalt that uses petroleum resin and adds pigments to the mixture. Colored asphalt uses light-colored or colorless cementing material, which is currently the most widely used variety. Modern petrochemical products such as aromatic oils, polymers, resins, etc. are used to prepare a mixture with the same performance as ordinary asphalt, and then add A certain kind of paint makes it appear a certain color. The types of colored asphalt pavement mainly include: asphalt mixture coloring, practical color aggregate coloring, colored asphalt mixture, colorless asphalt mixture, surface coating coloring materials, etc. [0003] The Chinese patent whose notification number is CN100410326C discloses a kind of colore...
