In a crack detection device (10), an image acquisition unit (21) acquires image data acquired by taking an image of a road surface from an oblique direction with respect to the road surface, An image classification unit (22) classifies image data acquired into an acceptable range with a resolution higher than a standard value, and an unacceptable range with a resolution equal to or less than the standard value. A data output unit (23) outputs acceptable data being image data of a part classified into the acceptable range as data to detect a crack on the road surface. An image display unit (24) displays data output.

A control device may obtain sensing data related to a paving material mat region laid by a screed assembly of a road paver. The control device may determine, based on the sensing data, a respective texture value and/or a respective height value associated with each portion of two or more portions of the paving material mat region. The control device may determine, based on the respective texture values and/or the respective height values of the paving material mat region, a finish value associated with the paving material mat region. The control device may cause, based on the finish value of the paving material mat region, one or more actions to be performed.

Methods and systems for distributed detection of road conditions and damage are described. In one embodiment, a method for distributed detection of road conditions and damage is provided. The method includes receiving, from one or more mobile devices, a plurality of reports of anomalies associated with roads in a geographic area. The method also includes storing the received reports of anomalies in a database and comparing each report of an anomaly to stored reports of previous anomalies in the database. The method further includes determining whether each report of an anomaly indicates road damage or a temporary problem. The method includes generating a prioritized list of locations of anomalies associated with one or more roads that have been determined to have road damage that needs maintenance and/or repair.

The invention relates to a milling machine (100) comprising a bottom side (11) on which at least two milling heads (1a-1f) are individually movable and controllable in at least one translational movement (15a-15f) in one transverse rail (13a-13f) each, the rails running parallel to one another.

A paving machine includes an implement, an elongated structure, a sensor arrangement, and one or more breakaway couplers. The implement modifies a surface during a movement of the paving machine. The elongated structure is coupled to a side portion of the paving machine and extends along a direction of the movement. The sensor arrangement includes sensor units arranged sequentially along the elongated structure. The breakaway couplers correspondingly normally retain the sensor units to the elongated structure. Each breakaway coupler includes a mounting structure and a retainer unit. The mounting structure is secured to one of the elongated structure or a corresponding sensor unit, while the retainer unit retains the other of the elongated structure or the corresponding sensor unit to the mounting structure by a retention force, which is adjustable.
