An arrestor bed for slowing an aircraft overrunning a runway, including an elongated excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio between 1:1.6 to 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

The present invention relates to a porcelain stoneware element for the construction of driveways.

Embodiments of a dry mix for producing a concrete composition are provided. The dry mix includes aggregate, cement, and bed ash. The bed ash contains the combustion product of a fluidized bed coal combustion reaction. Additionally, embodiments of a method of preparing the dry mix and embodiments of a method of preparing a concrete composition are provided. The dry mix is also suitable for repairing soil slips, and embodiments of a method of repairing a soil slip are also provided.

Embodiments of the present invention may provide encapsulation of waste (2) materials in a first (1), double (5), triple (7), or even quadruple (44) encapsulation. Encapsulation may include waste (2), ash (4), Portland cement (3), water, chemicals, or the like. Agglomerates formed perhaps with high energy mixing may be processed, cured, or the like.

A water-impermeable waterproof asphalt concrete composition having styrene isoprene styrene (SIS). The composition's waterproof performance due to its high cohesion and adhesion. The composition is durable and is not easily rutted, aged and/or stripped. In addition, the composition has a performance grade of PG 82-34, and can prevent water penetration and potholes. Furthermore, the asphalt concrete for prime coating and waterproof asphalt concrete can be applied to form an integrated structure by using a mixing/feeding system and can also be easily placed on site.

The invention provides a whole-granulation steel slag pavement base course material for a heavy-load pavement, which is prepared by uniformly mixing dry materials with water. The dry materials include a binder and a steel slag aggregate. The percentages in total mass of the binder and the steel slag aggregate are as follows: the binder is 3.4% to 5.0%, and the steel slag aggregate is 95.0% to 96.6%. The binder is prepared by mixing cement with steel slag micropowder according to a certain proportion, wherein the mass percentages of the cement and the steel slag micropowder are as follows: the cement is 70% to 90%, and the steel slag micropowder is 10% to 30%. The water accounts for 5% to 6% of the total mass of the dry materials.
