  • Patent number: 10437217
    Abstract: A modular irrigation controller has a robust ground path with high conductivity that can accommodate lightning induced power surges on field valve wires and common wires that are connected to a plurality of station modules. Sensitive electronic components in the station modules are thereby protected from damage. The robust ground path extends from conductors on circuit boards within the station modules through captive mounting screws to a metallic backplane and then through metallic grounding brackets within a pedestal enclosing the modules and the backplane. The grounding brackets are in turn grounded to both an earth ground stake and to a ground wire associated with the incoming one hundred and ten volt AC power.

  • Patent number: 9528000
    Abstract: A hot-mix asphalt paving mixture includes the use of a hard, angular, non-carbonate ½? minus igneous crushed rock, washed rounded No. 100 sieve silica sand particles, ½? minus recycled asphalt pavement particles, and a performance-graded bituminous liquid asphalt binder, thereby to produce an environmentally-friendly hot asphalt mixture that is laid with minimal compaction effort, and without the use of conventional compaction-aiding additives that chemically alter the viscosity of the liquid asphalt binder. During compaction, the rounded silica sand particles react with the igneous rock particles as a mechanical compaction aid, thereby allowing the angular particles to achieve proper aggregate interlock with minimal compactive effort. The aggregate composition comprises about 75% igneous crushed rock, about 5% processed round silica sand particles, about 20% recycled asphalt pavement, and about 5% binder. The resultant pavement is skid-resistant, resists rutting, and has a permanent dark color.

  • Patent number: 8536255
    Abstract: An acid modified asphalt binder is combined with an emulsifier solution to produce an emulsified asphalt binder. The acid modified asphalt binder may be formed by combining an asphalt binder, a phosphorous-based acid, and, optionally, a polymer modifier. The emulsifier solution may be produced by forming an aqueous solution of an amine and a phosphorous-based acid, which forms an aqueous solution comprising an amine phosphate. The emulsified asphalt binder may be combined with an aggregate to form a paving material. In other examples, the emulsified asphalt binder may be used alone, for example in a chip seal application, or in a diluted form, for example in a fog seal application.

    Abstract: A bituminous composition comprising a bitumen emulsion in an amount from about 2% to about 10% by total weight of the bituminous composition, and aggregate in an amount from about 90% to about 99% by total weight of the bituminous composition, wherein the bituminous composition is at a temperature range of about 50° C. to about 140° C. The bitumen emulsion comprises hard bitumen in an amount from about 50% to about 75% by total weight of the bitumen emulsion, the hard bitumen being characterized by a penetration number of about 100 dmm or less at 25° C. as determined according to the AASHTO Method T49, and an emulsifier in an amount from about 0.05% to about 2% by total weight of the bitumen emulsion, the emulsifier having a Hildebrand solubility parameter of at least of about 19 (MPa)½. Also disclosed are the methods of producing and using such bituminous compositions.

  • Patent number: 8454741
    Abstract: The invention provides a bituminous composition, a process for preparing a bituminous paving composition and process for bituminous paving having lower mixing, paving, and compaction temperatures than for conventional hot-mix paving while retaining sufficient performance characteristics of conventional hot-mix paving. The inventive paving process comprises the steps of injecting an aqueous solution comprising a lubricating substance into a heated, asphalt binder to provide a heated, foamed mixture; adding the heated, foamed mixture to a suitable, heated aggregate; further mixing the heated, foamed mixture and heated aggregate to coat the heated aggregate with the heated, foamed, asphalt binder to form a heated paving material; supplying the heated paving material to a paving machine; applying the heated paving material by the paving machine to a surface to be paved; and compacting the applied paving material to form a paved surface.

  • Patent number: 8444760
    Abstract: This disclosure relates to bituminous compositions and methods of producing the same. More particularly, the disclosure relates to the production of bituminous compositions formulated with performance-graded bitumen-containing solvent-free bitumen emulsions which exhibit controllable, temperature-dependent interfacial rheology. When employed in paving applications, these bituminous compositions develop adhesive strength and load-bearing strength properties at rates comparable to traditional hot mix paving compositions and at rates faster than traditional cold mix paving compositions.

  • Publication number: 20130104772
    Abstract: At least one embodiment of the inventive technology may involve the intentional changing of the stability of an emulsion from a first stability to a more desired, second stability upon the addition of a more aromatic asphaltene subfraction (perhaps even a most aromatic asphaltene subfraction), or a less aromatic asphaltene subfraction (perhaps even a least aromatic asphatene subfraction) to a emulsion hydrocarbon of an oil emulsion, thereby increasing emulsion stability or decreasing emulsion stability, respectively. Precipitation and redis solution or sorbent-based techniques may be used to isolate a selected asphaltene subfraction before its addition to an emulsion hydrocarbon when that hydrocarbon is part of an emulsion or an ingredient of a yet-to-be-formed emulsion.
