A system including a first feeder configured to transport asphalt, a second feeder configured to receive the asphalt from the first feeder, and a controller configured to control a speed of the first feeder and the second feeder in response to an input from an operator.

A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.

A high friction surface coating comprising a resin and an aggregate, the aggregate comprising a blend of calcined bauxite and particles of sandstone and/or Tuff. Optionally, the particles of sandstone and/or Tuff in the aggregate may be from the Paleozoic era, including the Carboniferous, Devonian, Silurian, Ordovician and Cambrian periods.

A bridge paving device includes one or more reference receivers to locate the bridge paving device in three-dimensional space. A computer apparatus receives the location of the bridge paving device and associates the location with a bridge paving design profile. The computer apparatus independently actuates a system of hydraulic actuators of the bridge paving device to level and orient the bridge paving device regardless of the travel surface the linear movement elements are running on. Additional hydraulic actuators may adjust the shape of the bridge paving device over time as the bridge paving device travels a linear distance of the bridge to be paved. The shape adjustment alters a crown or inversion applied to the bridge such that run-off characteristics are more variable and controllable along the entire span of the bridge.

A system and method for the construction of a hemp mat having consistent density whereby the hemp fiber mat may be used to strengthen ice or other entities for any number of applications and different types of construction designed such that it may be sturdy enough to stay bonded when it is transported, unrolled, and soaked during ice road construction but loose enough to break apart during spring to reduce blockage and environmental damage to the waterway on which the ice road was constructed.

Systems and methods of imprinting concrete having exposed aggregate. The imprinted concrete system comprises a concrete layer, an imprinted layer disposed on the concrete layer, wherein the imprinted layer comprises a decorative aggregate, and has been imprinted with an imprinting tool. In some embodiments, the decorative aggregate may be at least partially exposed.

A field-assembly dowel basket for concrete construction configured for in-the-field assembly from a small number of component parts, including dowels, dowel jackets, frame wires that are assembled into dowel basket sections. The dowel jackets may support different types of dowels, such as rectangular plate dowels, diamond-shaped plate dowels and rod dowels. The dowel jackets are firmly attached to the frame wires by leg-clip structures with three clips features including two leg clips, which attach to risers of the frame wire, as well as a central clip feature that clips to the crossbar of the frame wire, to securely support the frame wire and dowel to the dowel jacket. Multiple dowel basket sections are joined together by inline connectors connecting adjacent frame wires to fabricate an elongated dowel basket of desired length.
