Embodiment 1

[0016] A new type of asphalt for water seepage pavement, which is composed of the following components in parts by weight: 6 parts of granular SBS modifier, 3 parts of resin, 3 parts of antiaging agent, 0.15 part of sulfur, and the balance is added with matrix leach to 100 parts.

[0017] The preparation method of above-mentioned novel asphalt of water seepage pavement: comprise the following steps:

[0018] 1) Add granular SBS modifier and resin to the base bitum at 170-185 degrees Celsius;

[0019] 2) Put it into a high-speed shear colloid mill for 30 minutes to obtain substance A;

[0020] 3) Put substance A into a transition tank, add anti-aging agent and stabilizer, stir for 2.5 hours, keep warm at 175-185 degrees Celsius for 1-3 hours, and you get it;

[0021] 4) Detect the indicators of high viscosity modified asphalt.

Embodiment 2

[0023] A new type of asphalt for water seepage pavement, which is composed of the following components in parts by weight: 8 parts of granular SBS modifier, 5 parts of resin, 5 parts of anti-aging agent, 0.2 part of stabilizer, and the balance added with base leaching to 100 parts .

[0024] The preparation method of above-mentioned novel asphalt of water seepage pavement: comprise the following steps:

[0025] 1) Add granular SBS modifier and resin to the base bitum at 170-185 degrees Celsius;

[0026] 2) Put it into a high-speed shear colloid mill for 30 minutes to obtain substance A;

[0027] 3) Put substance A into a transition tank, add anti-aging agent and stabilizer, stir for 2.5 hours, keep warm at 175-185 degrees Celsius for 1-3 hours, and you get it;

[0028] 4) Detect the indicators of high viscosity modified asphalt.

[0029] In the present invention, specifically, the stabilizer is sulfur.

Embodiment 3

[0031] A new type of asphalt for water seepage pavement, which is composed of the following components in parts by weight: 7 parts of granular SBS modifier, 4 parts of resin, 4 parts of anti-aging agent, 0.2 part of stabilizer, and the balance added with base leaching to 100 parts .

[0032] The preparation method of above-mentioned novel asphalt of water seepage pavement: comprise the following steps:

[0033] 1) Add granular SBS modifier and resin to the base bitum at 170-185 degrees Celsius;

[0034] 2) Put it into a high-speed shear colloid mill for 30 minutes to obtain substance A;

[0035] 3) Put substance A into a transition tank, add anti-aging agent and sulfur, stir for 2.5 hours, keep warm at 175-185 degrees Celsius for 1-3 hours, and you get it;

[0036] 4) Detect the indicators of high viscosity modified asphalt.

Abstract

The invention discloses novel asphalt for a water penetrating pavement and a preparation method thereof. The asphalt is composed of the following components in parts by weight: 6-8 parts of a granular SBS modifier, 3-5 parts of resin, 3-5 parts of an anti-ageing agent, 0.1-2 parts of a stabilizer and the balance of matrix asphalt, totaling 100 parts. The high-viscosity modified asphalt disclosed by the invention is low in cost of material. Compared with an existing high-viscosity modified material, the compound material is low in price, can achieve the same effect, and has relatively high market competitiveness. The detecting index result of the high-viscosity modified asphalt fully meets the standards of the Ministry of Communications and the Ministry of Housing and Urban-Rural Development.

Description

technical field [0001] The invention relates to the field of chemical product preparation, in particular to a new type of asphalt for water seepage pavement. Background technique [0002] In order to adapt to the development of sponge cities, it is necessary to use high-viscosity modified asphalt, a new type of asphalt. Relatively large, and some of the index margins are not large. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a new type of asphalt with high viscosity and water seepage pavement. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a new type of asphalt for water seepage pavement, which is composed of the following components in parts by weight: 6-8 parts of granular SBS modifier, 3-5 parts of resin, anti-aging 3-5 parts of the agent, 0.15-0.2 parts of the stabilizer, and the balance is added to 100 parts of matrix leach. [0005] The preparatio...
