Embodiment 1-3

[0047] Embodiment 1-3: Prepare binder

[0048] The cementitious materials were prepared according to the materials and compositions shown in Table 1, and the cementitious materials A1, A2, and A3 were respectively obtained corresponding to Examples 1-3.

[0049] Table 1 Binder composition and formula

[0050]

Embodiment 4-6

[0051] Embodiment 4-6: Preparation of colored cavity ceramic particles

[0052] The pottery clay used in this example is mainly silty clay mainly composed of kaolinite, montmorillonite, quartz, potassium albite feldspar, etc., and the dyes used are iron oxide red, chromium oxide green, chromium titanium yellow, etc.

[0053] Mix sodium bicarbonate powder, pottery clay powder, and dyes according to the ratio shown in Table 2; add an appropriate amount of water and knead through a kneader to make colored pottery clay containing sodium bicarbonate; pass the pottery clay after the previous step kneading through a screw extruder Extrude and make dense colored clay particles; heat the colored clay particles to the corresponding temperature in a two-stage heating method (see Table 3) and keep for a period of time; continue heating and sintering to make multi-cavity colored ceramic particles. Corresponding to Examples 4-6, the colored cavity ceramic particles B1, B2 and B3 were resp...

Embodiment 7-9

[0059] Embodiment 7-9 prepares colored pavement material

[0060] Take the colored cavity ceramic particles B1, B2 and B3 prepared in Examples 4-6, put them into airtight containers respectively, then vacuumize the container and keep it for 5-20 minutes, so that all the cavities in the particles are in a vacuum state , and then spray the PCM phase change material into the container, the injection amount is 10-50% of the aggregate amount, and keep stirring until all the cavities in the particles are filled with the phase change material.

[0061] The colored pavement binders A1, A2, and A3 prepared in Examples 1-3 are mixed with colored ceramic particle aggregates B1, B2, and B3 containing phase change materials respectively to make colored pavement materials C1, C2, and C3. The ratios are: 9 / 100, 10 / 100, 11 / 100. Its road performance is shown in the table below:

Abstract

The invention provides a color pavement material. The color pavement material comprises a cementing material and an aggregate, the ratio of the cementing material to the aggregate is 5-20 / 100, wherein the aggregate is color cavity gap ceramic particles, and a phase transition material is absorbed in the cavity gap of the color cavity gap ceramic particles. According to the invention, a pore forming agent is added during the preparation process of the multi-cavity ceramic particles, general color cavity gap rate can reach 80%, and volume ratio of the effective adsorption phase transition material can reach 40%. The phase transition material is absorbed in the cavity gap of the multi-cavity gap ceramic particles, a phase transition process is carried out in the cavity gap of the multi-cavity gap ceramic particles, the cementing material and the phase transition material are tightly combined, stress concentration phenomenon is not generated due to minimal defect in the cementing material, internal stress generation can be avoided, and color effect of the color aggregate can be fully embodied.

Description

technical field [0001] The invention relates to a pavement material and a preparation method thereof, in particular to a colored pavement material and a preparation method thereof. Background technique [0002] Colored pavement has the functions of beautifying the environment and warning traffic. Colored pavement is widely used in Europe to remind road users which part of the road can be used at which time. Colored pavement is widely used in Europe to provide a separate lane for special road users, such as bus lanes dedicated to public transport, bicycle lanes, small motor lanes, electronic toll booths dedicated to emergency services and VIP card holders Lane. Colored roads are distinguished by color on some speed bumps. This distinction is very useful. It can effectively reduce traffic violations and increase traffic safety. In addition, the popularization of colored pavement can greatly change the image of the city and reflect the characteristics of the city. Not onl...
