Use of spike roller on an exposed concrete surface
According to examples, a method may include pouring a fluid ultra-high performance concrete (UHPC) mixture into a cavity, thereby providing a UHPC having at least one exposed surface. The method may include applying a liquid polymer onto the exposed surface of the UHPC, thereby providing a layer of liquid polymer onto the at least one exposed surface. According to examples, the method may include rolling the layer of the liquid polymer layer on the at least one exposed surface of the UHPC with a spike roller having a plurality of extended spikes. In some examples, the rolling may be applied with a predefined amount of pressure to cause the extended spikes to pierce the exposed surface of the UHPC, to incorporate the liquid polymer into the UHPC.
Integrated form for embedding a waterstop in a keyed concrete joint
Disclosed herein is an article of manufacture that increases the efficiency of forming a building material having a keyed joint with a waterstop imbedded within the building material. The article allows the easy formation of a keyed joint between formed solid slabs (typically concrete) with a waterstop properly imbedded between the slabs.
Paving machine membrane dispenser
An asphalt paving system comprising an asphalt paving machine, a plurality of dispensing shafts, and a plurality of rolls of pavement reinforcing membrane. The paving machine comprises a hopper is configured to store hot asphalt material. The plurality of dispensing shafts are mounted on the asphalt paving machine, where at least a portion of at least one dispensing shaft extends from at least one side of the paving machine, and at least a portion of at least one dispensing shaft extends to a front of the paving machine. Each roll of pavement reinforcing membrane is supported by one of the plurality of dispensing shafts. As the asphalt paving machine moves, the plurality of dispensing shafts dispense the pavement reinforcing membrane continuously beneath the asphalt paving machine and the hot asphalt material is dispensed from the hopper on top of the pavement reinforcing membrane beneath the asphalt paving machine.

AUTOMATICALLY ADJUSTING SWING LEGS FOR MOUNTING AND ALIGNING AND REORIENTING CRAWLERS
A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

Machine, system and method for resurfacing existing roads using premixed stress absorbing membrane interlayer (SAMI) material
Various implementations include a machine for resurface existing roads. The machine may include a premixed stress absorbing membrane interlayer (SAMI) material distribution component configured to distribute a premixed SAMI material on an existing road. The distributed premixed SAMI material may include a mixture and/or combination of binding material and pre-cut fiber material. The machine may also include a channel positioned adjacent and downstream of the premixed SAMI material distribution component. The channel may be configured to supply an asphalt mixture directly over the premixed SAMI material. Additionally, the machine may include a screed positioned adjacent the channel. The screed may be positioned to contact the asphalt mixture.
