Embodiment Construction

[0023] The following is further described in detail through specific implementation methods:

[0024] The present invention provides examples 1 to 6 of an oily cold-patch asphalt, and the ratio of specific raw materials is shown in Table 1.

[0025] Table 1 is a kind of raw material ratio of oil-based cold-patch asphalt Examples 1-6 ("--" indicates that it does not contain)

[0026]

[0027] Because the freezing point of diesel oil is usually -20~-35 ℃, the freezing point of kerosene is generally lower than-30 ℃, so embodiment 1~3 is summer formulation, and embodiment 4~6 is winter formulation.

[0028] Taking Example 1 as an example, the preparation process and application process of oily cold-patch asphalt are described.

[0029] A preparation process of oily cold-patch asphalt. At room temperature, add 30g of aromatic oil to 1000g of base asphalt and stir evenly, then add 30g of SBR latex or rubber powder and 40g of single-component epoxy resin and stir evenly, and then...

Abstract

The invention relates to the technical field of pavement patching materials, and particularly discloses oily cold patch asphalt and a preparation process thereof. The oily cold patch asphalt comprisesthe raw materials in parts by mass: 100 parts of matrix asphalt, 3-5 parts of aromatic hydrocarbon oil, 4-5 parts of a single-component high-molecular polymer, 5-7 parts of diatomite, 3-4 parts of petroleum resin, 3-5 parts of SBR latex or rubber powder and 18-20 parts of kerosene or diesel oil. The raw materials are uniformly stirred at normal temperature to obtain the cold patch asphalt in a light black flow pattern; by adopting the prepared cold patch asphalt, a user can purchase stones near pavement patching and obtain a required mixture as required, the components of repeated transportation of the stones are saved, the problem of high cost of a traditional cold patch mixture is solved, and meanwhile, the mixture does not need to be heated before patching and is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of road surface repair materials, in particular to an oily cold-patch asphalt and a preparation process thereof. Background technique [0002] As one of the main disease forms of asphalt pavement in my country, potholes will pose a great threat to driving safety, and will rapidly expand due to water intrusion and driving load. Therefore, potholes appear and must be repaired quickly. Traditional pothole repair is divided into two methods: hot repair method and cold repair method. The hot repair method uses hot-mix asphalt mixture, which is suitable for large-area repair and high temperature conditions, and most of the potholes are small and appear. The sudden nature of hot patch pits is extremely restrictive. [0003] The cold patching method has the advantages of simple operation and fast construction speed, but the asphalt cold patching mixture currently on the market is basically supplied to the user by ...
