摘要： A composition is described comprising a resin matrix reinforced with nonamphibole asbestos fiber or other inorganic fibers having similar aspect ratios, fiber diameters and hydrophilic surfaces, in a concentration of 5 to 85 phr, the fiber being coated with a glycol in a concentration of 3 to 75% by weight of fiber. The glycol will have the following properties:(a) liquid and stable up to and at the processing temperature of the resin;(b) liquid at temperatures of less than 50.degree. C. (122.degree. F.);(c) chemically unreactive with the resin;(d) low hygroscopicity; and(e) generally immiscible with the resin at ambient temperatures.Preferably the glycol will be ethylene glycol, propolyene glycol or a polyethylene glycol having a molecular weight not greater than 1500. An internal lubricant may also be used in the composition. Both thermosetting and thermoplastic resins may be used; good results have been obtained with polyvinyl, polyolefin and phenolic resins. The invention comprises the composition itself, the process for its formation, the coated asbestos fiber used for reinforcing the composition and shaped articles, such as pipe, made from the composition.

摘要： Diatomite-modified membrane and slurry seal mixes having improved properties. An impermeable membrane suitable for protecting cement bridge decks and roadways has from 9 to 14% by weight asphalt, 0.5 to 3.0% diatomite with a preferred diatomite/asphalt ratio in the range of 0.08 to 0.30, with the balance being fine aggregate (sand). This membrane can be placed by conventional paving equipment, can withstand temporary traffic loading prior to installation of a wearing course, can be preformulated in sheets, and is a crack resistant (i.e., self-healing) under normal traffic loads. Also disclosed is a slurry seal cold mix with improved abrasion resistance, adhesion/cohesion, and tensile strength. With these improved characteristics, slurry seals can be useful as bridge deck and roadway membranes in addition to its standard overlay uses.
摘要翻译：具有改进性能的硅藻土改性膜和浆料密封混合物。适用于保护水泥桥面和路面的不透水膜具有9至14重量％的沥青，0.5-3.0％硅藻土，硅藻土/沥青比例优选为0.08至0.30，余量为细骨料（砂）。该膜可以通过常规的铺路设备放置，可以在安装磨损过程之前承受临时的交通负载，可以预成型为片材，并且在正常的交通负荷下是抗裂的（即自修复）。还公开了具有改进的耐磨性，粘附/内聚性和拉伸强度的浆料密封冷混合物。通过这些改进的特性，浆料密封件除了其标准覆盖用途之外，还可用作桥面和道路膜。
