Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

A system and method for filling pot holes. The system includes transferring aggregate from an aggregate tank. Activator is likewise transferred from an activator tank. The activator is mixed with the aggregate to form a homogenized mixture. A liquid is introduced into a homogenized mixture to form a slurry and then a pot hole filler. The pot hole filler is directed through an exit end of a mixing tube.

Methods and systems for producing warm foam mix asphalt are disclosed. In some embodiments, the methods include the following: injecting an ethanol additive into asphalt binder having a temperature below the auto ignition point of ethanol to form a foamed asphalt stream; adding the foamed asphalt stream to a mixing zone; adding at least one of aggregate and reclaimed asphalt pavement to the mixing zone; adding a foaming agent to the mixing chamber; heating at least one of the mixing zone and the at least one of aggregate and reclaimed asphalt pavement; mixing the foamed asphalt stream and the at least one of aggregate and reclaimed asphalt pavement to form a warm foam mix asphalt; collecting emissions from the mixing zone, the emissions including ethanol vapors; and recycling the emissions to the mixing zone.

This present invention discloses a waterborne polymer modified emulsified asphalt mixture and the preparation method thereof, and particularly relates to a waterborne polyurethane emulsified asphalt concrete, a waterborne acrylic resin emulsified asphalt concrete, and a waterborne epoxy resin emulsified asphalt micro-surfacing mixture, and preparation methods thereof. A mixture containing a waterborne polymer modified emulsified asphalt forms a high-performance composite system having a spatial network structure, and has good performance and simple preparation process.

Disclosed is a glass fiber-reinforced composite material, an asphalt mixture using the same, and a manufacturing method thereof, the method comprising manufacturing, as a mixed structure, a bundle type fiber reinforcing material by coating with a polypropylene resin; a scrap reinforcing material having pellet or particle shaped glass fiber scrap, the glass fiber scrap having economical and outstanding physical properties and several strands of glass fiber; and adding the same to a hot-mix asphalt mixture, thereby capable of being injected at a plant construction site in a simple manner and improving the performance of the asphalt by preventing the phenomenon of the fiber becoming entangled within the produced hot asphalt mixture.

The present invention relates to an asphalt mixture that contains a polyester resin (A), a compound (B), an asphalt, and an aggregate. The aggregate contains an asphalt recycled aggregate. The compound (B) is a compound having 8 or more carbon atoms and having a hydroxy group or an amino group.

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

Reinforcing fibers, such as aromatic polyamide (aramid) fibers, are treated by coating with or embedding in a binder such as a Fischer-Tropsch wax. The treated fibers are divided into suitably-sized units, which are added to bitumen, aggregate and other ingredients in an asphalt cement concrete mix. The units shed fibers into the mix during the manufacturing process so that the fibers are distributed fairly evenly throughout the asphalt mixture. The binder may also impart beneficial qualities to the finished asphalt concrete.
