Uurimistöö hõlmab infrastruktuuriobjektide kogu elutsüklit - nende projekteerimist, ehitamist ning hooldamist, ehitustööde juhtimist, liikluskorraldust ja –ohutust ning teedevõrgu planeerimist. Geodeesia alane uurimistöö tegeleb kaasaegsete lahenduste väljatöötamisega ruumiandmete kogumiseks, analüüsiks ning visualiseerimiseks. Teedeehituslik ning geodeesia alane uurimistöö on tihedasti läbi põimunud ühistes rakenduslikes uurimisprojektides. Uurimisrühma koosseisus on ka Teede ja liikluse teadus- ja katselabor, mille peamiseks tegevusalaks on tee-ehitusmaterjalide katsetamine. Labor on akrediteeritud 2015. aastal Eesti Akrediteerimiskeskuse poolt sooritamaks katseid asfaltsegude, bituumensideainete ning täitematerjalide valdkondades. Katsetegevusega toetatakse Teedeehituse ja geodeesia uurimisrühma teadustööd ning täiendavalt pakutakse teenust teedeehitajatele ning teedeehituse tellijatele kvaliteedikontrolliks.
The main research topics of the Road Engineering and Geodesy research group are as follows: Research on stabilized pavement layers; Development of methodology for elasticpavement design; Research on the road construction materials (bitumen, fillers, asphalt mixes, etc.); Analysis of increase in traffic and itsimpact, traffic safety (road safety auditing and inspection, road network impactanalysis, safety analysis, etc.); Development of the calculation method forsteel tube bridges based on the interactionbetween arc and soil; Development of bridge managing systemsand life cycle calculation for bridges; Specification of the load bearing capacityfor Soviet era standard reinforced concrete bridges according loadings based onEurocode; Geoid modelling research with emphasison the Nordic-Baltic region; Development of geodetic infrastructure(e.g. establishment/validation of gravitydatabases, geoid modelling computations,mean sea surface modelling, studies ofshipborne GNSS to evaluate geoid modelsat sea) for finalizing hydrographic surveysin the Baltic Sea; Development of technological solutions forcombining different spatial data acquisition sensors in a mobile platform and corresponding data processing; Geodetic SAR for Baltic Height SystemUnification and studies for marine processes; Assessment of existing structures based onvisual inspections, non-destructive testingor analytical models. Analysis of optimalintervention and inspection planning; Development of transport planning specifications with enhancement of informationabout infrastructure and heavy equipmenttransportation needs based on validationof load testing results; Investigation of specifications for concretestructures service life beyond 100 years onroad infrastructure with development ofdurability assessment methodology.
