preparation example Construction

[0031] The present invention also provides a method for preparing the aforementioned emulsified transparent binder, which includes:

[0032] Step 1, heat the transparent binder to 100°C to 145°C, and store it for later use;

[0033] Step 2, soap solution preparation: add the required amount of emulsifier into the water and stir evenly, then add acid while testing the pH of the soap solution, and control the pH value of the soap solution between 1.5 and 4;

[0034] Step 3, heating the prepared soap liquid to 40°C to 65°C for later use;

[0035] Step 4, mixing the transparent binder and the soap solution to obtain the emulsified transparent binder.

[0036] Further, in step 1, the heated transparent binder is stored in the asphalt or modified asphalt tank of the emulsified asphalt production equipment for future use.

[0037] Further, in step 3, add the prepared soap liquid into the soap liquid tank of the emulsified asphalt production equipment, and heat it to 40°C to 65°C fo...

Embodiment 1

[0040] This specific embodiment discloses an emulsified transparent binder, its raw material components and weight percentages are as follows: the proportion of transparent binder is 40.5%, the proportion of water is 57.6%, the proportion of emulsifier is 1.1%, and the proportion of acid is 0.8%. The water in this embodiment is tap water, the emulsifier is a fatty alcohol and ethylene oxide condensate emulsifier, and the acid is dilute hydrochloric acid.

[0041] The preparation method of the luminous pavement of this embodiment, the steps are:

[0042] 1) Heat the transparent binder to 115°C and store it in the asphalt tank of the emulsified asphalt equipment for standby;

[0043] 2) Add the required amount of emulsifier into the required amount of water, stir evenly, and add dilute hydrochloric acid while testing the pH value. When all the required hydrochloric acid is added, the pH value is 2.9;

[0044] 3) Add the prepared soap liquid into the soap liquid tank of the emu...

Abstract

The invention discloses an emulsified transparent binder. The binder comprises the following components: a transparent binder, water, an emulsifier, an acid; the mixing amount of the transparent binder is 40.0-65. 0% of the total mixing amount, the mixing amount of the water is 31.0-59.45% of the total mixing amount, the mixing amount of the emulsifier is 0.25-2.0% of the total mixing amount, andthe mixing amount of the acid is 0.3-2.0% of the total mixing amount. Another object is to provide a preparation of the emulsified transparent binder. The emulsified transparent binder can be used forconstructing a natural color road surface under the condition of cold mixing and cold construction, and at the same time the road surface flexibility, natural color and various road surface performance are maintained.

Description

technical field [0001] The invention belongs to the technical field of road construction functional pavement, and in particular relates to an emulsified transparent binder and a preparation method thereof. Background technique [0002] In recent years, with the construction boom of BRT, trails, parks and scenic spots in my country, the construction of various functional pavements is in a period of rapid development, among which the research and construction of natural color pavements is an important aspect. [0003] The natural color of the pavement can be realized by using epoxy resin as the binder, but the pavement is rigid after the natural color pavement of epoxy resin is formed, and the pavement comfort is low. The current natural color pavement mainly adopts transparent asphalt binder and adopts the method of hot mixing and hot construction. However, the way of hot mixing and hot construction needs to consider the equipment cleaning and heating during the production a...
