A transition construction for bridging a building joint between two component parts of a building with at least one cover element that at least partially covers the building joint. The cover element is attached to a component part of the building via an anchoring structure, wherein the anchoring structure is configured such that the at least one cover element is selectively supported.

Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

A method of manufacturing a concrete substrate includes placing a first concrete layer on a support base configured to support the concrete substrate, positioning a concrete slab load transfer apparatus on a top surface of the first concrete layer, wherein the top surface of the first concrete layer supports the concrete slab load transfer apparatus, and placing a second concrete layer on the top surface of the first concrete layer such that the second concrete layer covers the concrete slab load apparatus.

A method and system for in situ cross-linking of polymers, Bitumen, and other materials to produce arbitrary functional or ornamental three-dimensional features using electron beams provided by mobile accelerators comprises defining a desired pattern for imparting on a target area, mapping the target area, defining at least one discrete voxel in the target area according to the desired pattern to be imparted on the target area, assigning an irradiation value to each of the at least one discrete voxels, and delivering a dose of irradiation to each of the at least one discrete voxels according to the assigned irradiation value.

This invention is in the field of asphalt construction or pavement applications, compositions and methods of use thereof. The invention also relates to methods of asphalt treatment, such as a step of applying onto an asphalt surface, under treatment conditions, a composition containing a biobased ester, at least one monoterpene, propylene glycol methyl ether acetate, a liquid intermediate made from polystyrene foam, sulfuric acid, D-limonene and soy methyl ester; carbon black pigment and styrene-butadiene complex.

An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.

The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

The present disclosure provides various aspects for mobile and automated processing utilizing additive manufacturing. The present disclosure includes methods for adding line features to a roadway surface. In some examples, the line features may include wires, conduits and electronic components. In some examples, the mobile additive manufacturing apparatus may create communication means into an advanced roadway in line features, which may be used for various communications including communications to and from autonomous vehicles. The communications may involve data related to the operation of systems of autonomous vehicles. In other examples, the line features may be dynamically colored with LED components.
