This invention discloses a room-temperature bio-based asphalt cold patch and its preparation method. The cold patch comprises 96.5-98 wt% recycled asphalt pavement material and 2-3.5 wt% bio-based asphalt cold patch liquid. The cold patch liquid comprises 60-70 wt% base asphalt, 10-20 wt% bio-based diluent, and 20-30 wt% bio-based regenerator. The preparation method includes the following steps: preparing epoxidized soybean oil methyl ester and hydrogenated ricinoleate methyl ester; mixing vegetable oil and its derivatives, fatty acids and their esters, natural small-molecule organic components, and oxalic acid at room temperature to obtain a bio-based diluent; heating the base asphalt to a fluid state and adding the bio-based regenerator, followed by cooling and adding the bio-based diluent to obtain the cold patch liquid; and adding the cold patch liquid to the recycled asphalt pavement material and mixing to obtain the cold patch. The bio-based asphalt cold patch of this invention has high initial strength, high pavement stability after repair, and significantly reduces the rework rate and the probability of recurring defects.

The application provides a data migration method and device and a computer readable storage medium. The method comprises the following steps: receiving a data migration request, wherein the data migration request carries a data copy of to-be-migrated data; in response to the data migration request, configuring distributed storage resources and object storage resources for the data copy; and performing hybrid storage on the to-be-migrated data according to the distributed storage resources and the object storage resources. The distributed storage resources and the object storage resources are reasonably configured by using the method, and the hybrid storage resources can be used to solve the problem that diversified storage requirements cannot be met.
