Problems solved by technology

[0020] Cold-patched asphalt is a material used for pavement repair, which requires a wide range of adaptability. It can be used to repair both shallow potholes and deep potholes. For this reason, it is best to have two different grains, coarser and finer. diameter of the mixture, but the maintenance department is only willing to use a material of one specification, and at the same time, the coarser particle size is easy to cause particle drop, so the cold paving material should be designed as a finer graded mixture

Abstract

The invention relates to an additive-free cold patch asphalt material and a preparation method thereof. The invention belongs to the technical field of road construction material. The material uses one of kerosene or diesel as solvent.The preparation method comprises the following steps: adding one of No. 90 road asphalt, No. 70 road asphalt and thermoplastic styrene-butadiene rubber (SBS) modified asphalt which are used as binders in one of kerosene or diesel according to a certain ratio to mix and obtain liquid asphalt, using a traditional hot mixture asphalt stirring device to mix the liquid asphalt with aggregate through a certain technology and prepare the cold patch asphalt material, cooling the cold patch asphalt material to the room temperature, and packaging with a sealed container for standby.

Description

1. Technical field [0001] The invention belongs to the category of road construction and belongs to the technical field of road engineering construction materials. 2. Background technology [0002] During the long-term use of asphalt pavement, there will be loose, potholes, peeling and other diseases. Pavement diseases not only reduce the service capacity of the pavement, but also affect the normal traffic of the road, and the potholes on the expressway may even cause traffic accidents. Therefore, the potholes and damages on the road surface need to be repaired in time. [0003] At present, hot-mix asphalt mixture is mostly used for repairing potholes on the road surface. It is feasible for road surface maintenance with concentrated locations and large engineering quantities, but for road surface maintenance with scattered locations and small engineering quantities, it is not only difficult to mix asphalt due to too little quantity. It is difficult for the plant to produce...
