The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.

The present invention relates to a method for preparing a flexible and tough polymer modified asphalt composition which comprises sparging an oxygen containing gas through a liquid high-vinyl polybutadiene modified asphalt, wherein the liquid high-vinyl polybutadiene modified asphalt contains from about 0.25 weight percent to about 20 weight percent of the liquid high-vinyl polybutadiene, wherein the oxygen containing gas is sparged through the liquid high-vinyl polybutadiene modified asphalt at a temperature within the range of about 400 F. to about 550 F. for a period of time which is sufficient to increase the softening point of the asphalt to a value which is within the range of 185 F. to 250 F. and to attain a penetration value of at least 15 dmm to produce the polymer modified asphalt composition.

The invention discloses a bionic laminated thermal insulation material, which imitates a multi-thin laminated and thin-layer micro-pore structure of Sequoia sempervirens bark with fire resistance, corrosion resistance and excellent thermal insulation performance. A low thermal conductivity microporous powder is used as main raw material, while reinforcing agent, plasticizer and porosity agent are added to form microporous thin-layer units, and each thin-layer unit is bonded and laminated to make a laminated thermal insulation material. The thermal conductivity of the finished products is as low as 0.02?0.05 W/m.Math.k, with good thermal insulation and mechanical properties, which can be used in a temperature range below 1000? C., with better thermal insulation and energy-saving effect and toughness than ordinary thermal insulation materials, significantly reducing the thickness of the insulation layer, and can be widely used in industrial furnaces, thermal engineering devices, insulation pipes and other fields.

A method of slowing an aircraft overrunning a runway, including covering an area adjacent a runway with irregular foamed glass bodies having aspect ratios of about 1:1.9 and diameters of about 10 mm to about 80 mm to define a bed, pouring liquid cement over the foamed glass bodies such that the cement infiltrates at least through the bed, curing the liquid cement to define a composite material of foamed glass bodies in a cementitious matrix, and crushing at least a portion of the composite material with an oncoming aircraft, slowing the aircraft. The composite material is at least 85 volume percent foamed glass bodies. When pouring the cement, the liquid cement flows over and around the foamed glass bodies. The aggregate bodies crush and break up before slip failure occurs when being overrun by an aircraft. The aggregate bodies intersect to define stacking angles of about 35 degrees. The cementitious matrix has a cementitious surface.
