Numeric road construction processes and their parts are today developed worldwide. This paper describes research in Finland, which is conducted with companies using national technology funding in a research and development project entitled "Intelligent Road Construction Site". In its entirety, four public research projects and two product development projects are today ongoing. One development project has already been completed, producing a Finnish version of an automated 3-D blade control system of road grader. New projects are in design and starting. In total, there are four research units and 16 companies or other infra organizations carrying out these activities. The financial investment into this research and development is EUR 2 million for the years 2001-2005.
The paper examines the economy and benefits of 3-D design method in concrete bridge engineering. New 3-D CAD design tools and 3-D measurement methods were developed and tested in the several real bridge construction projects in Finland during [2001][2002][2003][2004]. The paper describes these observations and suggests some conclusions for future developments as well as more expansive utilization especially in bridge construction in Finland. The next steps to be projected are also described.
This paper describes the first results of an R&D project "Intelligent Bridge" carried out in Finland. The aim of the project is to develop new methods for 3-D design of concrete bridges and further connect and bring the design models to the source information of site measurements. A new design concept for 3-D concrete bridge design was developed and preliminarily tested in a pilot design office. The site tests of the first implementations of real time CAD/CAM measurements using a 3-D robot tachometer, as well as a 3-D laser scanning technique, are presented and evaluated.
Abstract:The paper reports on the research work in the domain of automated road construction. A new method and prototype of automated road grader has been developed in Finland. The working experiments show measurable influence and quality as well as economic profit to be achieved by the new technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
