20240026616 · 2024-01-25 ·

A method and apparatus for deploying a tubular body onto a surface. The apparatus includes a main body movable in an advancing direction. The apparatus includes a deployment mechanism that deploys a tubular body directly onto a surface. The apparatus includes at least one container that stores an uncured protectant. The container is mounted on the main body. The apparatus may include a second container that stores a second protectant. The second protectant is different than the uncured protectant. The apparatus includes at least one curing device, which can cure the uncured protectant after the uncured protectant is applied to surface.

Infrastructure-scale additive manufacturing using mobile electron accelerators

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.

Road paver with heating element for a screed

A road paver comprises a generator, a control device and a screed, the screed comprising a basic screed and being suited to be modified, by selectively attaching or detaching broadening parts, from a first to at least a second, different screed configuration. The basic screed and the broadening parts each comprise one compacting unit and one electric heating element to be supplied with power from the generator for heating the compacting unit to prevent the laying material from adhering to the compacting unit and to finish a high-quality road pavement. The control device is configured to individually switch on or off each one of the two resistance wire windings of the heating element of the basic screed depending on the screed configuration determined by the control device to distribute electrical power generated by the generator to the individual resistance wire windings.

METHOD OF REPAIRING BITUMEN SURFACES AND DEVICE FOR CARRYING OUT THIS METHOD
20240093440 · 2024-03-21 ·

A device and method for using microwave heating to repair defects in bitumen surfaces. The device identifies a defect in a bitumen layer and divides a region around the defect into a primary heating zone and a secondary heating zone. Microwaves transmitted through waveguides arranged over the primary and secondary heating zones heat the bitumen layer in each zone such that the temperature of the primary heating zone is always 20? C. higher than the temperature of the secondary heating zone. After heating the bitumen layer around the defect, the defect is filled with a pre-heated bitumen mixture compacted until a top surface of the pre-heated bitumen mixture is level with an original surface of the bitumen layer.

RETROREFLECTIVE MARKING SYSTEM

Embodiments relate to a retroreflective marking system. A retroreflective marking system comprises a colorless binder, colored glass elements, and colored retroreflective elements, wherein the colored glass elements and colored retroreflective elements are positioned on top of the colorless binder such that color and retroreflectivity comes from the top of the system. This system also leads to improved skid resistance.
