Abstract: An asphalt composition has a modified asphalt binder. The modified asphalt binder includes an initial binder, an elemental sulfur, a recycled plastic, and a crumb rubber, the crumb rubber including a recycled material. The recycled plastic and the crumb rubber together define a binder modifier. The binder modifier and the initial binder together define an intermediate binder. The elemental sulfur is in an amount of 30 to 50 weight percent, by weight of the modified asphalt binder. The crumb rubber is in an amount of 10 to 20 weight percent, by weight of the intermediate binder.

Abstract: A modular partition system includes a non-metallic polymer frame assembly. Horizontal members of frame sub-assemblies of the frame assembly are slidably engaged such that a width of a rectangular opening of the frame assembly can be adjusted by sliding the first frame sub-assembly and the second frame sub-assembly together or apart. Front surfaces of the frame sub-assemblies include notches on their front surfaces. The system also includes a non-metallic rectangular polymer panels with non-metallic pegs. If the width of the rectangular opening is adjusted to a specified width, the notches and the pegs align and the pegs can insert into the notches, thereby attaching the panel to the frame assembly.

Abstract: A system for enclosing a utility line under a roadway or footway includes a plurality of modular walls formed from a polymer material, wherein the modular walls combine to form a duct unit defining an interior volume therewithin and having open axial ends. The system further includes a polymer plate overlaying the duct unit, a quantity of granular base material overlaying the polymer plate, and a plurality of interlocking paving blocks overlaying the granular base material, wherein the plurality of paving blocks combine to form a surface for accommodating foot or vehicular traffic. Further, the system includes one or more brackets removably fixed in the duct unit for holding the utility line within the interior volume.
