A construction and/or installation method for using phosphogypsum in embankment improvement includes preparing a phosphogypsum-containing embankment mixture, setting moisture content of an embankment mixture, paving a modified phosphogypsum-containing embankment, and reversely layering anti-seepage cushion layers from two sides of the embankment to the center of the embankment. The preparation of a phosphogypsum-containing embankment mixture can include the following: 90 parts by weight of phosphogypsum and 10 parts by weight of cement are weighted, uniformly mixed and stirred to obtain a base material mixture; and 2-4 parts by weight of sodium silicate is weighted and dissolved in water, and an obtained solution is added to the base material mixture to obtain the phosphogypsum-containing embankment mixture. The construction and/or installation method for using phosphogypsum in an embankment improvement can satisfy embankment strength and rebound modulus requirements, and can be widely applied to a filling-deficient area and an area with a relatively high yield of phosphogypsum solid wastes.

The present invention relates to a composite road module, unit and system. The composite road module comprising a first road and a second road extending substantially in parallel, one of the first road and the second road being configured for vehicles to travel according to a left-hand traffic rule, the other being configured for vehicles to travel according to a right-hand traffic rule, the first road comprising a first lane and a second lane, the second road comprising a third lane and a fourth lane, wherein the first lane and the third lane are in communication with each other, and are provided for vehicles to travel in a first direction, and wherein the second lane and the fourth lane are in communication with each other, and are provided for vehicles to travel in a second direction opposite to the first direction.

A method, system, apparatus, and computer program products provides the ability to dynamically define and generate inlet spacing along a road in a building information model (BIM) computer aided design (CAD) three dimensional (3D) model. A representation of a road is acquired in the BIM CAD 3D model, wherein the representation includes a geometry. An inlet spacing is defined for the road. Inlet locations for inlets are determined based on the inlet spacing. A determination is made regarding whether the inlet spacing and inlets satisfy design rules for the road. When the inlet spacing and/or inlets fail to satisfy the design rules, a different inlet spacing is selected from a group of preset integers, and the process repeats until the design rules are satisfied.

An energy harvesting roadway that includes a plurality of road segments and a power storage device electrically coupled to the plurality of road segments. Each of the plurality of road segments can include a surface asphalt layer, a first conductive asphalt layer located under the surface asphalt layer, a piezoelectric-based asphalt layer located between the first conductive layer and a second conductive layer located above a base asphalt layer. The piezoelectric-based asphalt layer can include a plurality of rigid piezoelectric elements and an insulating filler.

The combination parking structure, roadway and train station is a commuter-based system for relieving traffic congestion. The combination parking structure, roadway and train station includes a parking structure having a plurality of levels, at least one roadway, and a train station within the parking structure. A primary entry ramp branches from the at least one roadway, and a plurality of secondary entry ramps each branch from the primary entry ramp.

A roadway system of sinusoidal one-way roads which surround individual developed areas. A straight bidirectional road intersect the sinusoidal roadways at locations in which the sinusoidal roadways are substantially tangent to one another and orthogonal to the bidirectional road.

An elevated roadway for autonomous vehicles may include a pylon extending vertically from a ground anchor and comprising a metal tube defining a central cavity and a concrete column within the central cavity. The elevated roadway further includes a bracket coupled to the pylon and comprising a mounting plate secured to the pylon and a cantilevered road support member extending from the mounting plate. The elevated roadway may further include a cantilevered road section coupled to the pylon via the cantilevered road support member and comprising a joist structure structurally coupled to the cantilevered road support member, a road member above the joist structure and supported by the joist structure, and first and second side barriers along first and second sides of the road member, respectively. The road member may be adapted to receive a four-wheeled roadway vehicle.

A facility protection cover is disposed on a concrete foundation and covers a facility device disposed between the facility protection cover and the concrete foundation. The facility protection cover includes a cover body including a fiber-reinforced cement composite. The cover body includes two legs that are spaced apart from each other so as to be located on opposite sides of a facility device placement space. The facility device placement space accommodates the facility device. The cover body includes a bridging portion that bridges the two legs so as to extend over the facility device placement space. The cover body transmits a weight of a vehicle loaded on the cover body to the concrete foundation via the two legs, and restricts a separating relative movement of the two legs along a placement surface of the concrete foundation when the weight of the vehicle is loaded on the bridging portion.
