Definitions

  • the present invention relates in general to crack sealant and mastic packaging.
  • the present invention relates to meltable crack sealant and mastic packaging.
  • U.S. Patent No. 9,248,588, to Findley, et al. is said to disclose a meltable crack sealant package that includes a polymeric container and a crack sealant material contained therein, wherein the polymeric container includes a bottom portion including a rigid base and an upwardly extending rigid sidewall that terminates in and define an opening; wherein the rigid base and upwardly extending rigid sidewall cooperate to define a reservoir; wherein the rigid lid portion operatively engages with the bottom portion to close off the opening and thereby seal the crack sealant material within the reservoir in a watertight manner; and wherein methods of making and using the meltable crack sealant package are also disclosed.
  • U.S. Patent No. 8,017,681 to Guymon, et al. is said to disclose systems and methods for providing a thermoplastic product that includes packaging therefor, wherein implementation takes place in association with packaging of one or more ingredients of a thermoplastic product, wherein the packaging is used to contain the ingredients during storage and/or transportation, and wherein at least a portion of the packaging itself is an ingredient for inclusion into the thermoplastic product.
  • the entire packaging is said to be incorporated into the thermoplastic product for utilization thereof.
  • U.S. Patent No. 6,966,723, to Zentner is said to disclose a road repair kit and/or bridge joint repair kit that is comprised of an outer container, a measured amount of binder material and a separate and distinct measured amount of aggregate material, wherein in one preferred embodiment, the binder material is in a first consumable container (meltable bag) and the aggregate material is, likewise, in a second consumable container (meltable bag) inside the first consumable container, and wherein in another preferred embodiment, both the binder and the aggregate are contained in the same consumable container (meltable bag).
  • Mastic packaging generally shares the same disadvantages as crack sealant packaging.
  • Polypropylene bags e.g., TYVEK® bags, can easily tear, allowing liquid contents to spill.
  • Such bags allow mastic or crack sealant contained within to flow or deform and require a cooling process before being stacked on a pallet; further, they may require the use of cardboard gaylords to keep them fully contained on a pallet.
  • polypropylene bags degrade when exposed to the elements, exposing the mastic or crack sealant contained within.
  • rigid polypropylene containers also have disadvantages: they require long melting times to ensure that they are fully melted prior to application. Otherwise, the melted mastic or crack sealant containing a partially melted container will be non-homogenous, causing inconsistent product performance and perhaps clogging application wands. Blown polystyrene foam containers are fragile with regard to impacts and easily flake, contributing to litter and pollution of the environment.
  • an aspect of the present disclosure relates to a meltable mastic or crack sealant package including: a container including polypropylene, polyethylene, or both; the mastic or crack sealant disposed within the container; and a lid including polypropylene, polyethylene, or both, attached to or formed integrally with the container to enclose the the mastic or crack sealant within the container.
  • the mastic or crack sealant is not mixed within the container.
  • the aggregate and the binder are mixed within the container.
  • the the mastic or crack sealant is mixed before being disposed within the container.
  • the container is a corrugated container.
  • the container is waterproof.
  • the container and the mastic or crack sealant melt concurrently.
  • oil has been added to the mastic or crack sealant to the modify the viscosity thereof.
  • an aspect of the present disclosure relates to a method of forming a meltable mastic or crack sealant package including: providing a container including polypropylene, polyethylene, or both; disposing the mastic or crack sealant within the container; and attaching a lid comprising polypropylene, polyethylene, or both, to the container or forming the lid integrally with the container to enclose the mastic or crack sealant in the container.

  • FIG. 1 shows a polypropylene container with an aggregate and a binder disposed within.
  • FIGS. 2A and 2B show meltable mastic or crack sealant packages stacked on pallets.
  • crack sealant formulations vary widely depending upon manufacturer and depending upon the particular end use application for which they are intended.
  • crack sealants are composed of base asphalt (bitumen), polymer or rubber copolymers (e.g., styrenebutadiene- styrene copolymers), extenders and reinforcing fillers.
  • base asphalt bitumen
  • polymer or rubber copolymers e.g., styrenebutadiene- styrene copolymers
  • extenders and reinforcing fillers At most ambient storage and transportation temperatures, crack sealant compositions tend to be in solid form.
  • crack sealants are heated to temperatures whereby they become a molten liquid and are then applied in a heated liquid form by pouring and/or pumping. The molten liquid seeps into and fills the cracks and joints and then, upon cooling, re-solidifies within the cracks and joints thereby sealing or filling same.
  • crack sealant material is supplied to end users in poly bag-lined, rectangular corrugated cardboard boxes.
  • the corrugated cardboard box is lined with the poly bag.
  • Molten crack sealant material is poured into the poly bag-lined corrugated cardboard box.
  • the desired amount of crack sealant e.g., 20-60 lbs.
  • the crack sealant composition is permitted to cool, whereupon it solidifies and takes the rectangular shape defined by the interior space of the corrugated cardboard box.
  • the rectangular corrugated cardboard packages can be stacked on pallets and shipped to job sites.
  • the corrugated cardboard packages provide a flat surface, which can bear identification information.
  • the poly bags containing the crack sealant can be withdrawn from the corrugated cardboard box and inserted into the melting equipment together with the crack sealant material, with the poly bag melting and becoming part of the molten end use material.
  • the corrugated cardboard boxes can be recycled.
  • the corrugated cardboard boxes must be collected at the job site for recycling. In blustery conditions, the empty cardboard corrugated boxes can be blown away from their intended staging location.
  • the corrugated cardboard boxes can break down before or after the crack sealant has been used. And the corrugated cardboard boxes are susceptible to damage (e.g., deformation) due to compression (e.g., from the weight of the material itself, when stacked).
  • the term “mastic” is a general term that refers to a composite material used for roads, parking lots, and the like and consists of a mineral aggregate and a binder of one or more asphalts or one or more resins that include modifiers such as, e.g., a polymer- modified asphalt. Mastic is used to fill larger cracks and potholes and to pave surfaces, including load bearing surfaces.
  • crack sealant is general term that refers to materials that are used to fill and thereby seal cracks and joints in asphalt and cement pavement surfaces. Crack sealant is widely used to fill and thereby seal cracks and joints in highways, streets, parking lots and driveways from water penetration. The use of crack sealants prolongs the service life of such pavement surfaces.
  • Crack sealant materials are sometimes also referred to in the art by terms such as, for example: hot pour; crack seal; crack sealer; crack sealant; crack fill; crack filler; joint seal; joint sealer; joint sealant; joint fill; joint filler; rubberized asphalt; tar; polymer-modified asphalt; thermoplastic-modified asphalt; para-plastic materials; rubber-modified asphalt; traffic loop detector sealant; waterproofing membrane asphalt; modified asphalt; roofing asphalt; cold joint adhesives; marker adhesives; and other asphalt/resin/polymer compositions.
  • the terms “mastic” and “crack sealant” will be used, but each term should be understood to encompass all materials having the same general composition, use, or properties.
  • FIG. 1 shows a polypropylene container with an aggregate and a binder disposed within.
  • FIGS. 2A and 2B show meltable mastic packages stacked on pallets.
  • a meltable mastic package includes a container including polypropylene, polyethylene, or both, an aggregate and a binder disposed within the container, and a lid including polypropylene, polyethylene, or both attached to (e.g., by strapping or welding) or formed integrally with the container to enclose the aggregate and the binder.
