An asphalt mix tracking system having a data collection system adapted to determine at least one characteristic of the asphalt mix, a data control system adapted to receive data from the data collection system, a lot tracking system adapted to track a lot of the asphalt mix, a truck tracking system adapted to track a truck, and a pavement injection system adapted to identify the lot of the asphalt mix. The preferred asphalt mix tracking system is adapted to substantially continuously track the asphalt mix from a mixing site to a paving site. A method for tracking an asphalt mix including determining the at least one characteristic of the asphalt mix, communicating the at least one characteristic of the asphalt mix to the data control system, transporting the asphalt mix from the mixing site to the paving site, and injecting an identification means at the paving site.

A material placer includes conveyors on a frame for receiving material from a side dump trailer and conveying the material to a placing location. The conveyors can include a receiving conveyor for receiving material from the side dump trailer through an opening in a side of the placer, a funneling auger for funneling the material so it flows along a narrow flow path, a transfer conveyor for lifting the material after it is dumped from the side dump trailer, and/or a placing conveyor for placing the material at the placing location. The placing conveyor can be movable between a stowed position and a conveying position. A drive system for the conveyor may be located within a conveyor pulley to reduce the envelope of the material placer.

Asphalt composition for road pavement, which is excellent in drying strength, strength after immersion in water, and bending strength, a method for producing the same, and a road paving method. The asphalt composition includes asphalt, a polyester resin, and an aggregate. The polyester resin is a specific polyester, and the amount of the polyester resin ranges from 2 through 30 parts by mass, based on 100 parts by mass of asphalt. The method for producing an asphalt composition for road pavement, includes a step of mixing asphalt, the polyester resin, and an aggregate at 130 C. or higher and 200 C. or lower, wherein the polyester resin is used in an amount ranging from 2 through 30 parts by mass, based on 100 parts by mass of the asphalt. The road paving method including a step of laying the asphalt composition, thereby forming an asphalt paving material layer.

A system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material, alkali-based powder, and sand at a batching and mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material. The method may further include pneumatically applying the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The system may include a batching and mixing device configured to mix blast furnace slag material, geopolymer material, alkali-based powder, and sand to generate a non-Portland cement-based material, the non-Portland cement-based material including 4% to 45% geopolymer material by weight; greater than 0% to 40% blast furnace slag material by weight, 10% to 45% alkali by weight, 20% to 90% sand by weight, less than 1% sulfate by weight, and/or no more than 5% calcium oxide by weight; a conduit configured to transport the non-Portland cement-based material from the batching and mixing device; and a nozzle configured to receive the non-Portland cement-based material and combine the transported non-Portland cement-based material with liquid to generate a partially liquefied non-Portland cement-based material, wherein the nozzle is further configured to pneumatically apply the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The method may include mixing one or more of 4%-45% volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and combining the dry binding agent mixture with water at a nozzle to produce a sprayable concrete compound.

A limiting plate of a road paver is detachably attached to a traverse or to a chassis of the road paver to increase the basic working width. The limiting plate is arranged with variable spacing to a subgrade. In order to prevent a mix from flowing forwards in a direction of travel and at the same time improve the efficiency of a screw conveyor, in which a geometrically defined screw trough is formed, a limiting plate extension is arranged on the limiting plate so that it can be adjusted, particularly in the direction of the subgrade.

A high-grade asphalt composition includes 100 parts by weight of asphalt; 40-80 parts by weight of styrene-isoprene-styrene; 20-60 parts by weight of a polymer resin; 10-50 parts by weight of an anti-rutting agent; 2-15 parts by weight of a filler; 5-30 parts by weight of ceramic nanoparticles; 5-10 parts by weight of a binder; 3-15 parts by weight of an antioxidant; 1-10 parts by weight of a stabilizer; 5-20 parts by weight of a fiber; and 2-20 parts by weight of an adhesion promoter. A construction method is provided using the asphalt composition. The present asphalt composition is not easily rutted, aged and/or stripped. At the same time, the present asphalt can prevent water penetration and potholes, can reduce noise, and enable the roads to be paved at low costs.
