Pavement deflection measurement at traffic speed.
Application of laser in highway engineering journals.
In this era of technology lasers have a very vast application in highway engineering.
It results in rapid measurement and quick data collection.
It is the fastest and most accurate measuring method that can analyze objects to know how it works or to know its dimensions.
It doesn t require any setup or break down.
Application of lasers in highway engineering laser based road profile measuring system are non contact type system capable of measuring road profile and road deflection at normal traffic speeds.
Both laboratory and field applications are given.
Three laser scans two in the sitka spruce and one in structured mixture were collected using a reigl inc.
These measurements were then compared with those derived from the scanner.
In this study the laser scan data was used to create block models of the rockmass which improved the excavation of the tunnel by showing the undercut and overcut.
Most of the laboratory tests with the instrument have occurred at the ndevc which is located at the turner fairbank highway research center in mclean.
Application of laser scanning technology for civil engineering projects in serbian 3864 fig congress 2010 facing the challenges building the capacity sydney australia 11 16 april 2010 5 11 picture 1.
Application of lasers in highway engineering.
Optics and lasers in engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering emphasis is placed on contributions targeted at the practical use of methods and devices the development and enhancement of solutions and new theoretical concepts for experimental methods.
Lpm 300vhs high speed laser scanner.
The laser based system can measure the road profile and deflection accurately while traveling at an average speed.
Proposed another application of the laser scanning for stability analysis of tunnels in blocky rockmass.
Jla reflects the state of r d in photonic production sensing and measurement as well as laser safety.
These techniques have eased human work by making it simple and easy to use.
Several projects conducted with this laser system are then presented as examples of the capabilities of the instrumentation.
It is used various purposes like road profiling pavement surface deflection bridge deflection speed checkers etc.
This application is such an amazing application of laser in engineering fields.
In 2010 fekete et al.
Laser scanning of the corridor from the town of leskovac to fyrm border 2007 aircraft.
Field measurements were recorded at the same time and included tree diameter at breast height dbh and tree height.
Multiple locations can be measured from a single instrument position.
Also it saves effort and money.
