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.

Asphalt binders and methods for making and using same. In at least one specific embodiment, the asphalt binder can include a bitumen and a glyceride and fatty acid mixture. The glyceride and fatty acid mixture can include one or more triglycerides, at least 1 wt % of one or more diglycerides, and at least 5 wt % of one or more fatty acids, based on the combined weight of the one or more triglycerides, the one or more diglycerides, and the one or more fatty acids. The asphalt binder can be made by combining a bitumen and a glyceride and fatty acid mixture. A paving composition can be made by combining a plurality of solids and the asphalt binder. A road can include a plurality of solids mixed with the asphalt binder.

A composition for sealing and resurfacing a road surface includes a first material having at least a first emulsified asphalt, wherein the first material is applied to the road surface. The composition also includes a second material having a second emulsified asphalt and a driving surface material. The second material is applied to the first material such that the first material and the second material co-cure as a unified material.

This invention relates to asphalt compositions. More specifically, this invention relates to asphalt binder compositions including asphalt, elemental sulfur and polyethylene wax, and methods of making the same. In some aspects, the invention provides a sulfur wax asphalt binder composition that includes a base asphalt having viscoelastic properties, an elemental sulfur, and a polyethylene wax. The polyethylene wax is combined with the base asphalt and the elemental sulfur to create the sulfur wax asphalt binder composition. The polyethylene wax is present in the sulfur wax asphalt binder composition in an amount effective to increase the viscoelastic properties as compared to the viscoelastic properties of the base asphalt.

A method of forming an asphalt mixture can include mixing a bio-source material and a bitumen source to form a bitumen mixture. The bitumen mixture can be mixed with a catalyst to form the asphalt mixture. Particles can be added to the asphalt mixture to form a roofing-grade asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 93 C. and a penetration distance no greater than approximately 25 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104 C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 204 C., or any combination thereof. The asphalt mixture can be applied to a base material to form a roofing product. The asphalt mixture can be applied as a pavement product.
