The invention relates to a suspension bridge type self-supporting aerial metal structure, in which the main platform is designed having three levels. The upper level is intended for the passage of motor vehicles. The intermediate level is intended for the transportation, transmission and distribution of all existing public services, and other possible services. The lower level is intended for an urban public transport system. Thanks to its self-supported aerial design, the structure of the present invention can be built within cities following the same layout as existing roads.

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.

Disclosed are asphalt and asphalt binders and methods for making such compositions with sterols. The sterols improve various rheological properties. Also disclosed are methods of determining the changes or improvements of various rheoloical properties.

The Interpass: Uninterrupted, Grade-Level Interchange having One-way Approach and Departure Legs is a geometric design for an at-grade interchange of one-way roadways that has no conflict points and which allows uninterrupted, uniform-velocity traffic flow. The subject invention is neither an overpass, nor an underpass, nor an at-grade intersection, nor a grade-separated interchange, and it has comparatively few of the negative qualities associated with those types of roadway junctions. Uninterrupted, grade-level interchanges of the subject design, when connected into a directed transportation network having one-way roadway segments, can constitute the nodes of an intrinsically-safe, grade-level, arterial or collector transportation facility with superior controllability, efficiency and safety, compared to those of traditional facilities.

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.

Provided is a faucet fixture to which antifouling functionality is imparted without causing localized corrosion. The present invention is a faucet fixture comprising a metal base material and a plating layer partially formed on the surface of the metal base material. The metal base material contains at least one metal element species selected from the group consisting of copper, zinc, and tin. The plating layer contains at least one metal element species selected from the group consisting of chromium and nickel. An organic layer is further provided on the plating layer, with a passive layer present on the surface of the plating layer being interposed therebetween. The organic layer is bonded to the passive layer via the bonding of a metal element (M), which constitutes the passive layer, and a phosphorus atom (P) in at least one type of group (X) selected from the group consisting of phosphonate groups, phosphate groups, and phosphinate groups, with an oxygen atom (O) interposed therebetween (M-O—P bond). Group X is bonded to a group R (wherein R is a hydrocarbon group, or a group comprising an atom other than carbon at one or two locations within a hydrocarbon group). The phosphorus atom concentration in the portion of the surface of the metal base material on which the plating layer is not formed is lower than the phosphorus atom concentration in the organic layer provided on the plating layer.
