Abstract: This disclosure relates to pavement systems and methods for paving that are suitable for locations containing a generally weak subgrade with a California Bearing Ratio of four (4) or lower. The pavement system includes a first geogrid layer placed directly on the subgrade; a first granular layer upon the first geogrid layer, the first granular layer having a thickness of from 0.5 times to 20 times the aperture distance of the geogrid layer; a first geocell layer upon the first granular layer comprising a geocell and an infill material; and a capping layer over the geocell layer. A second geocell/geogrid layer can be placed beneath the capping layer, if desired. An optional surface layer may be applied upon the capping layer if desired. The resulting pavement system provides long-term support for pavements applied over the pavement system.

The method includes impregnating the pores with a polymerizable gas and polymerizing the gas. In some embodiments, the gas is derived from a paracyclophane, typically heated at low pressure.

Abstract: Geocells are disclosed herein that are made from polymeric strips having improved compaction and deformation resistance. The compaction resistance refers to the deformation of the geocell during installation, when the geocell is being infilled. The deformation resistance refers to the deformation of the geocell during service, which is simulated using procedures described herein.

Abstract: A process is provided for producing a compatibilized polymeric blend. A first thermoplastic polymer and a reactive moiety are provided to a progressive melt kneading apparatus. The reactive moiety comprises a first reactive group capable of reacting with the first thermoplastic polymer but not a second polymer and a second reactive group capable of reacting with the second polymer but not the first polymer. The first thermoplastic polymer and the reactive moiety are then melt kneaded so that the first reactive group reacts with the first thermoplastic polymer and the second reactive group is grafted to the first thermoplastic polymer, forming a molten self-compatibilizer. A molten second polymer is then provided. The molten self-compatibilizer is melt kneaded with the molten second polymer so that the second reactive group reacts with the second polymer to form a compatibilized polymeric blend. Also provided are articles formed from the compatibilized polymer blend.
