摘要：	Over the past 8 years, the International Engineering Scanning Program, directed by the Federal Highway Administration's Office of International Programs, has been successful in defining the best highway design, construction, and maintenance practices worldwide. Scanning teams, which are made up of representative from both the public and private sectors, identify state-of-the-art procedures and products that can be adopted and advanced in the United States to improve the quality of the infrastructure. The teams also showcase innovative practices employed in the United States, sharing innovative technology with the host countries. The geotechnical and structural engineers who participated in the most recent geotechnical engineering scan in March 1998--visiting Canada, Denmark, Germany, and France--accomplished their three goals. The first goal was to discuss practices for implementing load and resistance factor design (LRFD) methods with colleagues in Canada and Europe. The second goal was to investigate Canadian and European procedures and experiences with innovative contracting practices for subsurface investigations and for the design and construction of geotechnical features, such as earthworks, structural foundations, and earth-retaining structures. These practices include product warranties, design-build contracting, cost-plus-time bidding, and alternatives to low-bid award contracting. The team's third goal was to identify new or improved mechanically stabilized earth-wall technologies, ground-improvement methods, and in situ testing procedures. A sidebar provides a primer on allowable stress design (ASD) and LRFD design methods.
