“…Therefore, the new national standard [7] provides measuring the adhesion coefficient not by a portable control device PPC-MADI, but by the roughmeter method while measuring by a device to control the evenness and slipperiness of road surfaces PCRS-2 at the recommended measurement speed of 50 km / h or by the method [8] which is difficult to implement in the megapolises traffic congestion. Neither method is able to take into account all these factors when measuring on the surface, only modern mobile road scanners can cope with it, for example a car road scanner ADS-MADI® or 3D scanners are tested for texture evaluation, mainly the ZScanner®800 (Slovakia) [11]. There studies showed that more than two accelerometers are required [12] for detecting defects which is achieved on these scanners.…”

Researching results and monitoring urban highways with an upper layer of stone mastic asphalts on blastfurnace slag aggregates with a cuboid-shaped grain are presented in the paper. Crushed stone with such shape of grains is obtained after 3 stages of crushing on a modern domestic and imported crushing and sorting equipment. Relatively high properties of asphalt concretes on the basis of such aggregates have been confirmed by the tests' results. The optimality criterion and the MathCad software module have been used for the selection of well-graded aggregates. The exploitation of city road surfaces in Lipetsk, used without any intermediate repairs and defects for 13-14 years, has been a practical confirmation of such properties Keywords-stone mastic asphalt, cast slag crushed stone, evenness of road surfaces, surface roughness.

“…Furthermore, the reconstructed vector map presents many discontinuities due to the missed road boundaries. Such a result may be utilized to diagnose the pavements and curbs in road engineering [48]. However, for mapping, many of these cases can be deduced and fixed by an experienced human mapper, which, at present, cannot be interpreted by the proposed algorithm.…”

The high-definition map (HD-map) of road structures is crucial for the safe planning and control of autonomous vehicles. However, generating and updating such maps requires intensive manual work. Simultaneous localization and mapping (SLAM) is able to automatically build and update a map of the environment. Nevertheless, there is still a lack of SLAM method for generating vector-based road structure maps. In this paper, we propose a vector-based SLAM method for the road structure mapping using vehicle-mounted multibeam LiDAR. We propose using polylines as the primary mapping element instead of grid maps or point clouds because the vector-based representation is lightweight and precise. We explored the following: (1) the extraction and vectorization of road structures based on multiframe probabilistic fusion; (2) the efficient vector-based matching between frames of road structures; (3) the loop closure and optimization based on the pose-graph; and (4) the global reconstruction of the vector map. One specific road structure, the road boundary, is taken as an example. We applied the proposed mapping method to three road scenes, ranging from hundreds of meters to over ten kilometers and the results are automatically generated vector-based road boundary maps. The average absolute pose error of the trajectory in the mapping is 1.83 m without the aid of high-precision GPS.

“…The format of the STL file, which is an abbreviation of the 3D printing technology called stereolithography, was developed by the company 3D Systems. This file describes three-dimensional surface geometry of the model and is most commonly used to export data to 3D printers from CAD software or other programmatic 3D modelers [7].…”
