项目摘要

Titan Environmental Containment (TITAN), established in 2006, is a leader in the geosynthetics field in Canada. TITAN conducted a few in-situ evaluations of geogrid-reinforced pavement in Canada and showed that geogrids can mitigate crack propagation. TITAN also developed and deployed composite products of geogrids and geotextiles that has great potential to improve the nation's roadways in Canada's unique geography and environment. Considering there is strong demand for these emerging products, TITAN has partnered with the Center for Pavement and Transportation Technology (CPATT) at the University of Waterloo (UW) in this project toward the development of high-performance pavement geosynthetics. The objectives of the projects include: (1)develop advanced numerical models to investigate the effectiveness of geosynthetics as a reinforcement of pavement; (2) conduct field instrumentation to measure pavement responses and quantify the impact of geosynthetics; (3) predict the long-term performance of geosynthetic-reinforced pavement; (4) develop the design and construction guidelines of geosynthetic-reinforced pavement with updated information on thermal, hydraulic, and mechanical properties of materials. By completion of this research project, the improved geosynthetics for pavement structure will be developed for TITAN. These products are expected to have great potential to reduce compressive and tensile strains caused by traffic loading from above and frost heave from the bottom, leading to the reduction of pavement layer thickness or extension of pavement service life. The project will accelerate deployment of these new technologies in Canada and improve competitiveness of the partner company but also the broader Canadian market for these products. The essential outcome of this research project will benefit Canada in validating and quantifying the benefits of geosynthetic - reinforced pavement, especially in cold regions, when incorporated into the pavement design method and used as the guidance for construction.
Titan Environmental Containment(TITAN)成立于2006年,是加拿大土工合成材料领域的领导者。TITAN在加拿大对土工格栅加固路面进行了一些现场评估,结果表明土工格栅可以减缓裂缝扩展。TITAN还开发和部署了土工格栅和土工织物的复合产品,这些产品在改善加拿大独特的地理和环境中的国家道路方面具有巨大的潜力。 考虑到对这些新兴产品的强劲需求,TITAN与滑铁卢大学(UW)的路面和运输技术中心(CPATT)合作,共同开发高性能路面土工合成材料。这些项目的目标包括:(1)开发先进的数值模型,以研究土工合成材料作为路面加固材料的有效性;(2)进行现场测试,以测量路面响应并量化土工合成材料的影响;(3)预测土工合成材料加固路面的长期性能;(4)制定土工合成材料加筋路面的设计和施工指南,并更新材料的热、水力和机械性能信息。 通过本研究项目的完成,将为TITAN开发用于路面结构的改进型土工合成材料。预计这些产品具有很大的潜力,以减少由交通负荷从上方和从底部的冻胀引起的压缩和拉伸应变,从而减少路面层厚度或延长路面使用寿命。 该项目将加快这些新技术在加拿大的部署,提高合作伙伴公司的竞争力,并扩大这些产品在加拿大的市场。该研究项目的主要成果将有助于加拿大验证和量化土工合成材料加固路面的好处,特别是在寒冷地区,当纳入路面设计方法并用作施工指南时。
