Sealing compositions and application methods for sealing and protecting asphalt roof shingles or other porous roofing and construction materials are described for eliminating algae, mold and mildew, increasing granular adhesion, providing additional UV protection and significantly increasing the wind resistance of the roof or other construction material. The sealing composition includes an acrylic polymer that has been modified by a silicone surfactant to alter its wetting properties so as to promote wicking of the sealer under asphalt shingles and at open edges to prevent curling and water infiltration. The method of applying the sealing composition promotes uniform distribution of the product on the surface of installed roofs as well as enhances bonding between individual shingles by improved penetration on and between shingle layers to increase adhesion area.

The asphalt roofing material is delivered into a treatment chamber of a processor. Hot oil is passed through a jacket surrounding the treatment chamber. Heated asphalt forms a hot solid and/or a liquefied slurry. The hot solid and/or the liquefied slurry is then removed from the treatment chamber. The asphalt roofing material in the treatment chamber can be agitated to promote mixing. The asphalt is heated to a temperature in the range from 200 degrees Fahrenheit to 650 degrees Fahrenheit within the treatment chamber. The solid and/or liquefied slurry is milled after it has been removed from the treatment chamber. The solid and/or the liquefied slurry is cooled after it exits the treatment chamber, preferably to a temperature in the range of approximately 90 degrees Fahrenheit to 110 degrees Fahrenheit. The hot solid and/or the liquefied slurry is passed through a hammer mill after the hot solid and/or the liquefied slurry exits the treatment chamber to reduce the particle size of the solid particles.

A shingle includes a reinforcing mat layer, an asphalt layer and an exterior layer. The asphalt layer is on top of the mat layer. The exterior layer includes structural-grade lightweight aggregate granules that are disposed on top of the asphalt layer. In making a roofing shingle, a mineral composition is heated to cause the mineral composition to fuse. The fused and expanded mineral composition is milled to form lightweight structural-grade aggregate granules. An asphalt layer is deposited onto a top surface of a reinforcing mat layer. A layer of structural-grade lightweight aggregate granules is applied onto the top layer. An adhesive asphalt strip is applied onto the layer of structural-grade lightweight aggregate granules. A lightweight aggregate pulverized dust is applied to a bottom surface of the mat layer.

Used and manufacturing scrap asphalt shingle material processed into a fine material comprising smaller sized pieces of shingle material with a relatively high aggregate content is finish processed into shaped products by grinding and heating the aggregate and smaller sized pieces of asphalt shingle material into a homogenous mixture, extruding the homogenous mixture, and forming the shaped products via molding or cutting the extruded mixture. A surface treatment material may be embedded into a softened surface of the shaped products.

An asphalt roofing material recycling system and method is used to recycle new and used (post consumer) asphalt materials, such as asphalt shingles, rolled roofing and tar paper that may include granules, fibers or other particles. The asphalt material, which may be in bundles, is broken up and separated and then provided to a cooled recycling vessel. Dry ice is added along with the asphalt material to be recycled. The dry ice removes any moisture present and super-cools the material making it brittle and easier to chip and break up. The recycle vessel includes a number of high speed shippers having tulip hear chipping teeth as well as one horizontal mixer element which stirs the material and makes sure all material is ground. The resulting course to fine powder can be separated by screening and stored as power or compressed into bricks or briquettes.

An asphalt paving mixtures suitable for roadway paving is formulated by mixing very soft penetration asphalt having a penetration value on the order of 300 to 400 and a melt point of 110° F. with recycled or reclaimed asphalt roofing shingles and/or recycled or reclaimed asphalt pavement granule material having a much higher melt point and a much lower penetration value. 10% to 30% of the recycled or reclaimed asphalt material in the final mixture will bring the formulation into compliance with PG grade paving asphalt. The asphalt paving mixture may utilize recycled asphalt shingle granules of approximately 50 mesh in size and preferably between 10 and 50 mesh while a powder may be utilized that is sized below 50 mesh.

The present invention comprises an asphalt roofing shingle with integrated thin film solar cells that is easy to install and scalable to each particular application. The system of the present invention comprises a standard asphalt roofing shingle manufactured with an integrated thin film solar cell connected to two electrodes configured on opposing sides of the shingle. The shingle is dimensioned to that of a standard asphalt shingle. Roofing nails, which are used to install the shingle to the roof, physically attach the shingle to the roof, may also establish an electrical connection between the electrodes of the respective shingles creating a unified electrical circuit amongst the attached solar shingles.

A method is disclosed for recycling asphalt roofing shingles and incorporating them into hot mix asphalt for use in applications such as asphalt pavement construction. Unlike previous methods, the asphalt from ground shingles is mixed with and becomes an integral component of the asphalt binder, instead of acting primarily as part of the aggregate. The asphalt content of the shingles mixes with heated asphalt binder to produce a single asphalt phase, and the asphalt from the shingles acts as asphalt in the final composite.

The invention discloses a data-based method for estimating loss of roof sheathings by considering wind load correlativity. The method is used for estimating the wind-induced loss of the roof sheathings adopting wood structures. In a calculation process, a probability density function of wind loads on the roof sheathings is estimated first and then extreme value distribution of the wind loads is obtained according to a conversion process method; extreme states of the roof sheathings are expressed by using relationships between extreme values of the wind loads on the roof sheathings and a resistance force, and then a destruction probability of the roof sheathings is calculated; and finally the loss of a whole roof is estimated. The method has the characteristics that a joint probability density function of the wind loads is obtained through Nataf change, so that the correlativity existent between the wind loads is considered and the influence of the wind load correlativity on wind-induced loss assessment of the roof sheathings is quantified. Meanwhile, the method can be expanded to the wind-induced loss estimation of other roof members such as asphalt shingles.
