Roads

Building on its long track record and rich experience in evaluating road projects, CTIEngineering supports you in calculating the effect of a road improvement project or otherproject evaluation.

CTI quantitatively evaluates the effects ofroad development projects in line with thecharacteristics and purposes of theproject.

For some of the items to be evaluated inroad development projects, we convertthem into benefits (monetary values) soyou can use them in a cost-benefitanalysis.

As to the method of calculating thebenefits, we clarify theoretical groundsciting overseas and precedent cases, and,taking experts’ opinions into account,summarize the method of calculation in amanual.

Road Project Evaluation (New projects, reevaluation, post-evaluation)

Examples of benefits can be estimated: Holiday traffic Winter traffic Lifting of traffic regulations Elimination of disaster risk Elimination of risk of isolated areas Improved reliability of traveling time Improved driving experience Improved emergency life-saving rate Improvement of local medical care Increased number of tourists visiting the

area Improved amenity of urban space Reduced division within a neighborhood Improved functions along roads Improved environment

Roads

By a 2.5 D FEM analysis that simulates the lay of the land, soil, road structure, pavementstructure, mitigation works, etc., we quantitatively identify the effects of various types ofmitigation works and propose measures designed to deliver the maximum effects.

Measures against Road Vibrations

Step 1: Select the mitigation measure based on quantitative analysisof mitigation effects.Step 2: Determine the specifications, scale, and layout of the mitigationwork based on the results of FEM analysis.Step 3: Support the client in ordering the works based on detaileddrawings, execution plans, estimates and calculation, etc.

3 steps for considering

measures against road vibration

STEP1 Select the mitigation measure based on quantitative analysis of mitigation effects

InputGenerating conditions: Where vehicles run,the speeds, weights, shapes, predominantvibration frequency of the groundTransmission paths: Density of each type ofsoil and structure, Poisson’s ratio, dampingconstant, elastic wave velocity, etc.

OutputA table of comparison of various types ofmitigation works that comprehensivelyexamines all factors such as the effect of eachtype of works on reduction of vibration,workability, reliability, and approximate cost ofexecution, and selects the one that is bestsuited to the site.

45

Measures against Road Vibrations (cont.)

STEP2 Determine the specifications, scale, and layout of the mitigation work based on the results of the analysis

In examining the specifications, scale, and layout of the mitigationworks to be selected, we determine the optimal ones by conductingmultiple FEM analyses while varying their physical values, layout, etc.

STEP3 Support the client in ordering the works based on detailed drawings, execution plans, estimates and calculation, etc.

In vibration mitigation works projects, which are conducted lessoften than noise mitigation works, it is necessary to order theconstruction works in an optimal way considering the executionmethod based on the type of mitigation works. CTI Engineeringprovides the client with optimal support from various divisionson the environment, design, execution, etc. working incoordination, who compile calculation sheets based on detaileddrawings, execution plans, etc., and provide general instructionsand warnings for execution of works.

Examples of checklist when ordering construction works Does the candidate have

a prescribed productionrate?

Does he have specialmachines?

Does he give grounds forthe calculation of thenumber of daysnecessary for execution?

Is his proposal consistentwith similar works?

Bridges

Regarding the performance of bridges with severe deterioration, the conventionalmaintenance and management methods centered on visual inspection were limited to stop-gap measures to repair only the damage concerned.To meet clients’ requests to know the level of load bearing, durability, etc. of suchdeteriorated bridges, we propose non-destructive inspection approaches that can easilymeasure the shape and vibration of those structures and assess their health level.

In-depth bridge survey technologies - Vibration and shape measurement for performance diagnosis -

● When measuring the vibrations at many points of bridgegirders, we can efficiently conduct the survey by using alaser Doppler velocimeter that is easily movable.

● We can measure damaged parts in 3D by scanning theshape of seriously damaged bridge girders, etc.

● By directly analyzing the 3D shape data, we canaccurately assess the effect of deterioration.

Results of measurement of the numberof passing vehicles by vehicle weight

Features1. Can assess changes in the state of a structure quantitatively by measuring continuous vibration

and distortion and analyzing characteristic values.2. Can calculate the vehicle weights and traffic volume of passing vehicles from the results of

measuring the vibrations and distortion of bridges, and determine the actual status of traffic load.3. Based on vehicle weights and traffic volume, we can check for fatigue of the floor slabs and

main beams of bridges in a way suited to the actual situation.

In-depth bridge survey technologies (cont.)◆ Structure performance identified by our 3D shape measurement method

Features1. The 3D shape measurement method enables high-precision measurement in a short time with a

laser scanner, high-precision photographic measurement system (3D photogrammetry system), etc.2. By accurately measuring the forms of deformation, cracks, deteriorated sections due to collision and

other external forces, progress of corrosion and fatigue, etc. and conducting non-linear analysis, wecan accurately assess the effects of deterioration on structures.

3. By placing reinforcing members fitted to actually measured shapes and analyzing them, we canidentify and propose effective reinforcing solutions.

[Step 4: Mid- and long term cost forecastd]

[Step 5: Direction of maintenance and management, upgrading]

[Step 6: Developing follow-up plans]

Survey all social infrastructures you are in charge and identify facilities to be selected for action plans.

Based on the repair and renewal cycles of each facility, set an appropriate plan period (e.g. 60 years).

Based on the facility register, results of inspection, the realities of maintenance and management, summarize the current status and issues to be addressed of each facility.

Based on the plans for individual facilities, add up the mid- and long term cost forecasts.

To equalize the mid- and long-term costs, examine the method for defining the priority among facilities.

Propose solutions to implement maintenance cycles focused on individual facility plans.

Examples of facilities concerned: Bridges, tunnels, banks and shore protection, drainage pump station, sand-control dams, sewage plants, playground equipment, etc.
