Abstract:
Asphalt emulsions, methods of forming asphalt emulsions, and composite pavement structures formed from the asphalt emulsions are provided herein. In an embodiment, an asphalt emulsion includes a base asphalt component, water, and an oxidized high density polyethylene. The base asphalt component is present in an amount of from about 15 to about 70 weight %, the water is present in an amount of at least about 25 weight %, and the oxidized high density polyethylene is present in an amount of from about 1 to about 20 weight %, where all amounts are based on the total weight of the asphalt emulsion. The oxidized high density polyethylene has an acid value of from about 5 to about 50 mgKOH/g. The asphalt emulsion is free of aggregate and other mineral materials.
Abstract:
A system includes a control system and a Remote Terminal Unit (RTU). The control system is configured to communicate data with one or more field devices via the RTU. The RTU includes a motor configured to vibrate the RTU unit. The RTU also includes an acceleration sensor configured to measure an acceleration of the RTU. The RTU also includes an I/O module configured to transmit a displacement computing by the acceleration of the RTU.
Abstract:
Asphalt emulsions and methods of forming an asphalt emulsion are provided. In one example, the asphalt emulsion includes a base asphalt component present in an amount of from about 40 to about 60 wt. % of the asphalt emulsion. Water is present in an amount of from about 40 to about 60 wt. % of the asphalt emulsion. An oxidized high-density polyethylene wax is present in an amount of from about 0.5 to about 5.0 wt. % of the asphalt emulsion. A slow-setting cationic emulsifier is present in an amount of from about 1.0 to about 2.0 wt. % of the asphalt emulsion.
Abstract:
A door access control system associates a unique passive identifier with each one of a plurality of doors for which controlled access is desired. Each of the identifiers can be attached to a location adjacent to each respective door. A smart phone with a predetermined scanning application can scan or read a respective identifier of a door for which access is desired. A representation of the door identifier along with an identifier of the smart phone can be transmitted to an access control unit. A data base of the access control unit can be interrogated to determine if that smart phone identifier is authorized to open the designated door. If authorized, then an access command can be transmitted to a local access control module that can release a locking mechanism for the respective door.
Abstract:
Foamed asphalt compositions, recycled asphalt compositions, asphalt pavement, and methods of forming asphalt pavement using the foamed asphalt compositions are provided herein. An exemplary foamed asphalt composition is in a cellular matrix form and includes a base asphalt component and oxidized high density polyethylene. An exemplary asphalt pavement includes a recycled asphalt layer that includes the foamed asphalt composition and a recycled asphalt component. An exemplary method of forming asphalt pavement includes combining a base asphalt component and an oxidized high density polyethylene to form an asphalt mixture. The asphalt mixture is foamed using water and compressed air to form a foamed asphalt composition. The foamed asphalt composition and a recycled asphalt component are combined to form a recycled asphalt composition. A recycled asphalt layer is formed with the recycled asphalt composition.
