A construction and/or installation method for using phosphogypsum in embankment improvement includes preparing a phosphogypsum-containing embankment mixture, setting moisture content of an embankment mixture, paving a modified phosphogypsum-containing embankment, and reversely layering anti-seepage cushion layers from two sides of the embankment to the center of the embankment. The preparation of a phosphogypsum-containing embankment mixture can include the following: 90 parts by weight of phosphogypsum and 10 parts by weight of cement are weighted, uniformly mixed and stirred to obtain a base material mixture; and 2-4 parts by weight of sodium silicate is weighted and dissolved in water, and an obtained solution is added to the base material mixture to obtain the phosphogypsum-containing embankment mixture. The construction and/or installation method for using phosphogypsum in an embankment improvement can satisfy embankment strength and rebound modulus requirements, and can be widely applied to a filling-deficient area and an area with a relatively high yield of phosphogypsum solid wastes.

Systems and methods for a ground water filtration system are described. The ground water filtration system includes paver blocks designed to facilitate liquid seepage between the paver blocks and to route the seepage to a preferred area. The ground water filtration system additionally provides at least one layer of stone to facilitate flow direction of the seepage to an outflow pipe. At least one geogrid fabric is also provided to further enhance ground water filtration.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

A design and construction method for using modified phosphogypsum in a roadbed and slope, where the method includes preparing a phosphogypsum-containing roadbed mixture, setting moisture content of the roadbed mixture, preparing a phosphogypsum-containing slope mixture, and construction of a roadbed and slope. The preparation of the phosphogypsum-containing roadbed mixture includes 90 parts by weight of phosphogypsum and 10 parts by weight of cement, and uniformly mixed and stirred to obtain a base material mixture; and 2-4 parts by weight of sodium silicate is dissolved in water, and the obtained solution is added to the base material mixture to obtain the phosphogypsum-containing roadbed mixture. The design and construction method are simple, can satisfy roadbed strength and rebound modulus requirements, and can be widely applied to filling-deficient areas with a high yield of phosphogypsum solid wastes.

A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire.
