摘要： An inner drum for use in a dryer/mixer in connection with the production of an aggregate-binder mix includes a plurality of mixing paddles disposed on the outer surface of the inner drum and arranged in a plurality of rows. The mixing paddles are configured to rotate through a mixing chamber as the inner drum rotates within an outer drum of the dryer/mixer to mix aggregate and binder together. Interstitial spaces are formed between rows of mixing paddles and material leads, where aggregate material preferentially travels as the inner drum is rotated, extend along the mixing chamber. At least one interstitial mixing paddle is located on the outer surface of the inner drum and in one of the interstitial spaces at one of the material leads. The interstitial mixing paddle rotates through the mixing chamber as the inner drum rotates to also mix the aggregate and binder together.

摘要： A method for storing and providing pavement data related to a paved road area that includes paved roads formed by paved road portions that are each paved by a separate asphalt lot. The method includes providing a computer-based system that receives and presents pavement data related to pavement used in constructing the road. An as-built model provides a digital map of a location where the paved road area is located and is overlaid by a digital road model overlays that replicates the paved roads and includes user-selectable digital road segments for each of the paved roads. Each digital road segment corresponds to and is based on only one of road portions. A pavement data set is associated with each digital road segment and includes pavement data related to the asphalt lot used in forming the road portion. When a digital road segments is selected, corresponding pavement data is displayed.

摘要： A method for producing an asphalt concrete blend that includes the steps of drying and heating aggregate in a single and only dryer, preferably via direct heating, and without use of a pre-dryer. The aggregate is then combined with asphalt cement, preferably via indirect heating, such that the blend has an asphalt cement components (ACC) percentage of at least 25% percent to form an aggregate mix. Liquid asphalt cement may also be added to the aggregate mix. Preferably, the asphalt cement content of the final asphalt concrete blend is provided by a maximum of 70% ACC. In certain cases, the asphalt cement content of the asphalt concrete blend is comprised of ACC and liquid asphalt cement.

摘要： A system for tracking and presenting pavement data related to a paved road area. The system includes a computer-based mapping system configured to generate a digital map of a real-world location having a paved road area and a digital reconstruction of at least a portion of the paved road area that is overlaid onto the map. The reconstruction includes two or more different user-selectable digital road segments that each corresponds to a different portion of the paved road area and is defined by two or more geographic coordinates. For each digital road segment, a corresponding data set includes pavement composition information and other information, including the geographic coordinates that define the selected digital road segment. When a user selects a digital road segment, at least a portion of the pavement data set corresponding to the selected digital road segment is displayed to the user via a display.

摘要： A stirring blade includes a first member having a first flat surface and a second member having a second flat surface, wherein the stirring blade is rotatable about a rotational axis in a state where the first and second flat surfaces are opposed to each other and spaced by a first distance across the rotational axis. When the stirring blade is rotated about the rotational axis with the first and second flat surfaces at least partially immersed in an object to be stirred, the object to be stirred having entered between the first and second flat surfaces is discharged in a direction away from the rotational axis by a centrifugal force and, simultaneously, the object to be stirred is sucked into and between the first and second flat surfaces from a direction along the rotational axis.

摘要： A storage silo apparatus having a storage silo including a shell wall, a secondary wall spaced radially outwards from the shell wall, and a space having a first width formed between an outer surface of the shell wall and an inner surface of the secondary wall. An insulation layer located in the space is narrower than the space such that an air gap is formed within the space. The air gap is formed radially adjacent the insulation layer and is configured to resist heat transfer between the shell wall and the secondary wall.
