Abstract: A telescopic bar for load transmission which, if anchored in concrete slabs, creates a support between them, forming semi-rigid joints, and prevents differential settlement of the slabs, by enabling rotation in the vertical direction about a joint axis. The telescopic bar transmits a load from one slab to an adjacent slab, ensures perfect leveling of the slab surfaces, and enables removal and reuse of the slab at a later time. The telescopic bar may be used for constructing floors of easily manufactured prefabricated materials, and creates a new paradigm for the construction of roads, seaports, airports, railways, industrial areas, etc.

Abstract: Methods, systems and devices for detectable warnings are disclosed.

Abstract: A screed assembly for a paving machine is disclosed. The screed assembly includes a screed plate having a front edge, a first plate positioned in front of the front edge of the screed plate. The first plate defining having a first thickness. A temperature sensor is coupled to the first plate. The temperature sensor is configured to determine a temperature of a paving material, whereby the temperature of the paving material is measured before the paving material comes into contact with the screed plate.

Abstract: A multifunctional and multi-story crossroad for intensive land use relates to urban road construction engineering and solves technical problems of urban traffic jams through space division and streamlined design, without occupying the land outside the road. It achieves: operating smoothly without red lights, large vehicle-free intersection space on the ground, large parking areas, long “side of the road” border between the parking area and roads, bicycle exclusive system. Technical elements include: learning from building design, multi-story crossroad, “Turning Right and Looping Back technique”, “exclusive bikeway interlayer”, “adding a lane”, and “large steps above ramp of a tunnel.” It is a combination of a smoothly flowing crossroad technique, viaduct and the tunnel. The main purposes are: for new construction and renovation of crossroad in congested cities, and development of city fast lanes, elevated roads and tunnels.

Abstract: A field-assembly dowel basket for concrete construction configured for in-the-field assembly from standardized components. This allows a number of standard components, including clips, connectors and wire frame components, to be conveniently transported and stored on construction sites to facilitate on-site assembly of dowel baskets on an as-needed, where-needed basis. Since the dowel basket components are much smaller than assembled baskets, they can be shipped and stored much more cost effectively. Standardization of components allows mass production, consolidates inventory management, and avoids the need for ad hoc fabrication for each construction site. On-site fabrication largely eliminates welding from the dowel basket fabrication process (wire frame clips may involve welding), avoids shipping of fabricated dowel baskets, and allows assembly of dowel basket by construction workers as opposed to highly skilled welding shops.
