Abstract

The embodiment of the invention discloses pouring type granulated asphalt and a preparing method thereof. The asphalt comprises an outer shell material, an inner core material, an accelerant, a delaying agent, a plasticizer and an adhesive. The pouring type granulated asphalt can be directly added into a mixing vat, asphalt granules are smashed and molten through high shearing force and heat of collected materials, an asphalt mixture is mixed, and the defect that liquid asphalt needs to be transported by heat insulation vehicles and needs to be stored at a high temperature after reaching the site is avoided; the liquid asphalt can be stored and transported at a normal temperature, energy is saved, the circular economy is developed, and the environment harmonious development is protected.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of asphalt granulation manufacturing, in particular to a pouring granulated asphalt and a preparation method thereof. Background technique [0002] Crude oil undergoes deep processing in petrochemical refineries, and light components go downstream to produce high value-added products. Heavy component bitumen raw materials also play a vital role in the infrastructure construction process. Asphalt raw materials require high temperatures during storage and transportation. Components such as polycyclic aromatic hydrocarbons that are volatile for a long time are harmful to health. The development of a kind of asphalt that can be stored and transported at room temperature is an important measure for the coordinated development of energy conservation, development of circular economy, and environmental protection. [0003] In the process of asphalt road construction, heavy traffic asphalt a...
