    Abstract: 一种土工格室(100)及其制造方法,该土工格室(100)包括多条筋带,该多条筋带在多个接点处彼此连接而形成多个单元格,其中,在每个接点处,多条筋带中的两条或更多条相邻筋带通过插件而彼此插接在一起,并且每个接点被胶体(5)覆盖。该土工格室(100)能够在施工现场容易地张拉至预设的状态,并且还能够防止切缝的撕裂,防止土体从切缝泄漏,以及防止插件生锈和腐蚀。由于胶体(5)、筋带、插件互相粘接在一起,显著地提高了接点处的剥离强度。优选地,插件的端部被胶体(5)完全覆盖而形成端盖(51,52),胶体(5)与筋带、插件彼此粘接在一起形成柱体,进一步增强了接点的结构稳定性,并且使得整体结构更美观。

    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.

    Abstract: The co-polymer soil subgrade binder relates to compositions utilizing ionic polyampholyte co-polymers in combination with soil to form improved subgrade soil binder compositions for supporting roads and pavement surfaces. The binders were aqueous solutions of three synthetic ionic variations of polyacrylamide: cationic poly(acrylamidopropyl trimethyl ammonium chloride), anionic hydrolyzed poly(acrylamide) and the ampholytic terpolymer poly(acrylamide- co-sodium acrylate-co-(3-acrylamidopropyl) trimethylammonium chloride). Mechanical testing of soil samples showed that a 50% aqueous solution of the ampholytic terpolymer (TPAM) gives the best properties in terms of strength and toughness. Also, the use of this ampholytic terpolymer gave better soil mechanical properties than the traditional standard, Portland cement under equivalent conditions.

    Abstract: A soil structure, for example a roadbed or levy, is made by admixing into soil from the course of the soil structure (a) calcium oxide, (b) at least one of cement kiln dust, lime kiln dust, fly ash, or cement, (c) a polymer binder for soil that is substantially gravelly, or liquid glass if the soil contains substantial quantities of pozzolanic material, and (d) water. The admixed soil is compacted into a roadbed or other soil structure of predetermined dimensions. After a predetermined amount of time, the liquid sodium metasilicate will catalyze hardening of the admixture if the soil contains sands or substantial quantities of pozzolans, otherwise the binder will cause hardening of the soil.

    Abstract: Provided herein are roadways containing polyurethane materials. A roadway includes a base layer of a compacted in situ material and/or a wear layer disposed on the base layer. One or both of these layers may include the polyurethane material to bind other components in the layers and to form more robust and durable roadway structures capable of withstanding operating loads of the roadway. In some embodiments, the polyurethane material is added to the wear layer by mixing in situ soil and/or foreign aggregate with polyurethane material or by dispensing the polyurethane material over the existing partially formed wear layer. The base layer may or may not include a polyurethane material. The type, concentration, distribution, and processing of the polyurethane material in the wear layer may be the same or different than that in the base layer.
