Thermoplastic composition for sealing roadway joints
Thermoplastic compositions useful for sealing longitudinal joints of substrates, for example, roadways and pavement, are provided herein. Formulations including the composition and methods of using the thermoplastic composition to seal longitudinal joints are also disclosed.
Pot hole filler composition and method of making same
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.
Modified nonvolatile cold asphalt binder and recycled asphalt mixture using thereof
A nonvolatile cold modified asphalt binder and a nonvolatile cold recycled asphalt mixture using the same are manufactured by optimally mixing a petroleum asphalt, a native asphalt, a polymer modifier, process oil, and an adhesive strength enhancer. The nonvolatile cold modified asphalt binder includes at least one petroleum asphalt selected from a straight asphalt or a blown asphalt; at least one native asphalt selected from gilsonite, glance pitch, and grahamite; a rubber-modified-compound (RMC) polymer modifier which is a vinyl aromatic hydrocarbon-conjugated diene block copolymer including at least one of a styrene-butadiene block copolymer (SBS), a styrene-isoprene block copolymer (SIS), and a styrene-ethylene-butylene block copolymer (SEBS); at least one process oil selected from paraffin oil, naphthenic oil, aromatic oil, natural oil, and mineral oil; and at least one adhesive strength enhancer selected from rosin esters, modified acryls, modified silicones, polyvinyl esters, and silicone resins.
Coating system for asphalt and related methods
A coating system and related methods for an airfield surface or a roadway is described. The coating system may include a stable cationic emulsion for application to the airfield surface or the roadway. The stable cationic emulsion may include a) an asphalt blend comprising gilsonite, wherein the gilsonite is modified to possess a positive charge, b) one or more polymers, and c) one or more surfactants not including a cationic surfactant. The coating system may also include a fine aggregate material for application to the stable cationic emulsion applied to the airfield surface or the roadway.
Hybrid composition and method for the repair and maintenance of asphalt and concrete surfaceways
A sealant material composition for sealing asphalt includes a non-fiber asphalt emulsion between about 20.0 wt. % and about 60.0 wt. %, carbon black between about 0.5 wt. % and about 5.0 wt. %, an aggregate between about 1.0 wt. % and about 10.0 wt. %, wherein the aggregate is amorphous aluminum silicate, and a hydrophobic additive between about 0.1 wt. % and about 1.0 wt. %.
Poly(acrylated polyol) and method for making and using thereof as asphalt rubber modifiers, adhesives, fracking additives, or fracking fluids
The present invention relates to a thermoplastic copolymer, block copolymer, and statistical copolymer comprising plural acrylated polyol monomeric units having different degrees of acrylation of hydroxyl groups. The acrylated polyol monomeric units have an average degree of acrylation greater than 1 and less than the number of the hydroxyl groups of the polyol. The present invention also relates to a method of making the thermoplastic copolymer, block copolymer, and statistical copolymer, and using them in various applications, such as asphalt rubber modifiers, adhesives, or an additive in a fracking fluid for oil fracking.
