A unit is disclosed for use in transferring fluids between two or more locations. The fluid transfer unit may include a body having a first end and an opposing second end, an inlet fitting connected to the first end of the body, and an outlet fitting connected to the second end of the body. The fluid transfer unit may also include a screen disposed inside the body between the inlet and outlet fittings, and at least one seal disposed at an end of the screen and configured to retain the screen at a desired location inside the body during transportation of the fluid transfer unit.

The present invention provides a method for producing a road making material and a road making material, the road making material comprising more than 10% polyvinylchloride (PVC) by weight and the polyvinylchloride having a glass transition temperature of no more than 180 C.

A compactor for operation on a surface includes: a frame; at least one compacting drum coupled to the frame; a drive system for accelerating and decelerating the compactor at an acceleration rate and a deceleration rate, respectively; and a controller for: controlling the drive system, and based on at least one variable, altering at least one of the acceleration rate and the deceleration rate.

Outdoor paving systems and methods of installing paving systems are described herein. The paving systems have a drainage layer of drainage stones. The drainage layer has a top surface and a bottom surface. The paving systems also have a paving layer abutting the drainage layer and covering the top surface of the drainage layer. The paving layer includes a permeable material. The permeable material includes an aggregate material bonded together by an elastomeric binder. The paving layer forms a containment field surrounding a perimeter of the drainage layer to restrict movement of the drainage stones of the drainage layer outwardly towards the surrounding ground surface.

Described herein are asphaltite-based adducts and polymers and methods of making the same. Asphaltite may be modified with a reagent such as polyphosphoric acid. The reagent may modify the asphaltite or portions or moieties thereof to possess a positive charge. The reagent may also activate the asphaltite or portions thereof to enable epoxy and/or urethane polymerization reactions within the asphaltite or portions thereof, and/or to enable cross-linking of the asphaltite-based polymers or adducts. Products incorporating asphaltite-based polymers and adducts are also described.
