A method, system, and computer program product for repairing cracks in structures by automatically transferring filler materials along a magnetic force pathway inside the structures. The method may include identifying a crack in a structure. The method may include analyzing dimensions and positions of the crack. The method may include identifying an array of magnetic coils near the crack, wherein the array of magnetic coils can create a magnetic path to the crack. The method may include determining an appropriate filler material reservoir connected with the structure based on the array of magnetic coils and the crack in the structure. The method may include transmitting instructions to release a quantity of the filler material mixture from the appropriate filler material reservoir connected with the structure for each of the one or more cracks.

The present disclosure relates to a plant for manufacturing heated asphalt mix. In particular, the disclosure relates to a batch asphalt mix plant for using a microwave heating vessel located in close proximity to a storage silo to heat asphalt mix at the point of storage using a batch production method.

A heat insulation sheet and a sheet material using the heat insulation sheet. The heat insulation sheet is provided with a fixing layer that is arranged between a base material and a carbon sheet. The fixing layer is made of a pressure-sensitive adhesive. The base material has flexibility. The carbon sheet is made by rolling expanded graphite and has a thickness from twenty-five micrometers to one hundred micrometers. In the sheet material, activated carbon is arranged opposite to the fixing layer side of the heat insulation sheet, and a surface material is arranged on a surface of the activated carbon. The fixing layer can be constituted in such a manner that a hot-melt adhesive is arranged in a reticulate manner.

A mobile asphalt plant for producing asphalt includes a heating unit, a container unit, a plurality of augers, and an injector. The heating unit includes one or more heaters to generate heated gas, a tank to hold heat transfer oil, and one or more first plenum tubes extending from the heaters to within the tank. The first plenum tubes transport the heated gas to the tank to heat the heat transfer oil. The container unit includes a hopper to receive the aggregate material and one or more second plenum tubes extending from the one or more first plenum tubes and extending within the hopper. The second plenum tubes transport the heated gas from the first plenum tubes to heat the aggregate material. The augers are arranged as a series of augers, with a first one of the augers receiving the aggregate material from the hopper. Each of the augers conveys the aggregate material to a next one of the augers. Each of the augers heats the aggregate material using the heat transfer oil from the tank. The injector is connected to one of the augers and injects asphalt oil into the aggregate material to produce asphalt.

A portable device for transporting asphalt repair materials for use in repairing potholes in asphalt pavements. The device has a body with a hopper compartment for transporting and dispensing asphalt mix materials. Emulsion oils are held and dispensed from a separate emulsion oil tank. An emulsion pump provides emulsion oils to a spray wand. The emulsion oil tank includes an emulsion rejuvenator apparatus which works to prevent separation of the emulsion oils. A control circuit actuates the rejuvenator any time that the emulsion pump is turned on to supply emulsion oils to a spray wand to spray emulsions onto the road repair site.
