Problems solved by technology

[0002] The mixing method of asphalt mixture generally adopts the method of heating the crushed stone to a certain temperature, spraying liquid hot asphalt into the mixing drum, and mixing and stirring to form asphalt mixture. The processing of this traditional asphalt mixture requires heat transfer oil. Equipment such as heating devices, storage tanks, heating pipelines, and heating pumps have high installation costs, large floor space, poor mobility, and high energy consumption, especially for small-scale mobile colored mixing equipment. The processing cost is too high

Embodiment Construction

[0016] See figure 1 , figure 1 It is the structure diagram of the screw extrusion mixing equipment, as shown in the figure, the screw extrusion mixing equipment has a geared motor unit 1, a cooling liquid cavity 2, a cooling liquid inlet 3, a small bag packaging equipment 4, a material liquid extrusion port 5, a single screw or Twin-screw 6, coolant outlet 7, hot melt asphalt inlet, the operation process is as follows: start the geared motor unit 1; turn on the cooling water, the cooling water enters the cooling liquid cavity 2 from the coolant inlet 3 and from the coolant outlet 7 Normally flow out; the hot melted liquid asphalt enters the screw extrusion mixing equipment from the hot melt asphalt inlet 8, and is stirred by a single screw or twin screw 6 and then extrudes the solid asphalt from the material liquid extrusion port 5, and then enters the small bag packaging equipment 4 for processing package. Among them, the temperature of the hot melted liquid asphalt is 160°C, ...

Abstract

The invention discloses a method for directly mixing solid asphalt to prepare an asphalt mixture, comprising the following steps: a. Preparation of solid asphalt, mixing liquid asphalt with pigments, and extruding through a screw extruder with cold water to obtain solid asphalt; b. 1. Heating and mixing the prepared solid asphalt and the aggregate in a mixer to obtain an asphalt mixture, wherein the solid asphalt accounts for 3-6% by weight of the asphalt mixture. The method for directly mixing the asphalt mixture with the solid asphalt provided by the invention not only saves the equipment required by the traditional asphalt mixture preparation method, but also reduces the production cost and saves the site. Moreover, by packing the solid bitumen in bags, it can be transported with high flexibility.

Description

Technical field [0001] The invention relates to a method for preparing asphalt mixtures, in particular to a method for directly mixing asphalt mixtures with solid asphalt. Background technique [0002] The mixing methods of asphalt mixture are generally used to heat the crushed stone to a certain temperature, and then spray the liquid hot asphalt into the mixing drum to mix and stir to form an asphalt mixture. The processing of this traditional asphalt mixture requires heat transfer oil Heating devices, storage tanks, heating delivery pipelines, heating delivery pumps and other equipment have high cost, large floor space, poor mobility, and high energy consumption. The processing cost is particularly high for small and colorful mixing equipment that needs to be moved. Therefore, a processing method of asphalt mixture with low cost, low energy consumption, small floor space, and flexible movement becomes a technical problem that must be solved. Summary of the invention [0003] Th...
