Damage to concrete and bridge expansion joints;Buckling, fissuring of asphalt pavementRutting

Fewercolderdaysandshorterwinters

Reduced snow removal but increased freeze-thaw degradation of asphalt

Intermittent or permanent floodingSurface damagedWeakening of key infrastructure support (bridge pilings)Damage to critical drainage infrastructureIncreased costal erosion – road collapseExacerbate salinity (corrosive effect)

Extremeprecipitations May overwhelm drainage infrastructureErosion, scouring, slop failure, flooding

Extremewindsandstorms

Wind damages bridges, gantries, signs, electricity networks, lightningStorm surge means damage from increased wave height and strength

Increasing Climate Resiliance ofRoads

1.Understandvulnerabilities ofthenetwork;2.Howlevelofrisk changesovertime;3.Identifyingpotentialadaptationresponses;4.Actions toreducerisk;5.Strategicplanningdecisionsontheground(materials,design,maintenanceprocedures)



Identify vulnerabilities andfuturerisks

1. Highqualityassetdata(incompleteornotadequate,difficulttoaccess)

ASSESSRISK:- Generalassetinformation(location,design,materials)- Geology,topography,hydrologyanduseofadjacentland- Climatethresholdsofassets- Assetcharacteristicswhichincreasevulnerability- Climatechangeprojections,futuredevelopmentsofthearea

TWOPARTS:A. ComputermethodsB. Fieldinspectionsandaction



Barriers1.Counterproductive policies

eg.EUWaterFrameworkDirective:limit totheamountofwaterthat can be discarded from asite.

2.Lack offunding (reduced budgetformaintenance)Barrier tointroductionofnewapproaches

3.Challengesindeveloping general guidelines (localinfo)



Adjusting standards:TheFrenchexample

• 2015Systematicreviewofstandardsandguidelinesfordesign,maintenanceandoperationsoftransportinfrastructure;

• Revisionof800standardsforroads;• 3groups:

a) Noneed forrevision (eg.Noise,landscaping design)b) Need revision (eg.Pavementdesign)c) Need forfurther climate parameters (maintenanceofurban

roads)



Standards for design, maintenance and operation are based on specific values of climate-related variables, whereas climate projections are often

given as ranges of values.



Prioritising AdaptationAction

1. LevelofriskBudgetconstraints(monitoringasset/doingnothing)

2. Identifymostcost-effectivetimeforaction

3. Decideonlevelofacceptanceofrisk(typeofroad,trafficvolumes,strategicvalue,…)
