Infrastructure condition monitoring: Embedded sensors and scanning techniques could monitor and diagnose the condition of pavement, bridges, tunnels, highway overpasses, retaining walls, etc.
Transportation infrastructure life-cycle management deals with maintenance decision making of transportation facilities such as pavement, bridges, and railways under budget constraints.
Secondly, in allusion to five kinds of transportation infrastructure: pavement, bridge, tunnel, side slope and ancillary facility, the existing infrastructure testing indexes were summarized, and the relations between traffic safety and these testing indexes were quantified.
The proposed method estimated the total emission from different steps of construction process (raw material production, material transportation and onsite construction) by different project types (e.g. subgrade, pavement, bridge, and tunnels).
Broken pavement, bridge expansion joints and unevenly matched road surfaces (repaved on half a lane, careworn on the other half) create a cognitive dissonance in the works and you'll often feel as if the wheels have suddenly gone out of alignment.
This paper reviews the latest development of the GPR's primary infrastructure applications, namely buildings, pavements, bridges, tunnel liners, geotechnical and buried utilities.
This technique is currently used in a large number of studies in the field of civil engineering, such as the analysis of state of pavements, bridges, tunnels, buildings, in the detection and location of installations, as well as in the characterization of building materials.
In saline regions, infrastructures (e.g., structures under earthquake, pavement slabs, bridge decks, airfield runways, railway sleepers and railway bridges, even high-speed railways and concrete structures in ocean) are attacked by sulfate compounds (Na2SO4, MgSO4, etc)., coupled with dynamic loading.
IDOT requires a minimum of 24 MPa 14 days compressive strength for concrete used in pavements, structures, & massive structures, 22.1 MPa 14 days compressive strength for concrete used in pavement and bridge deck patching, and 27.5 MPa 14 days compressive strength for concrete in bridge superstructure.
The civil engineer today is concerned with an even larger transportation field e.g., traffic studies, design of systems for road, rail, and air, and construction including pavements, embankments, bridges, and tunnels.
Weigh-in-Motion (WIM) systems are used, among other applications, in pavement and bridge reliability.
