Kvalitetsvurdering av vinterdrift/vedlikehold av fortau og andre gangarealer i Trondheim, med vekt på fremkommelighet og skaderisiko
(Master thesis, 2011)Bakgrunnen for denne masteroppgaven er de vanskelige fotgjengerforholdene som har preget Trondheim de siste vintrene. Værforholdene har vært svært varierende, med store snøfall og store svingninger i temperaturen. Dette ... -
Kvantifisering av mikroplastproduksjon langs E18 Tvedestrand-Arendal
(Master thesis, 2020)Omgivelsene rundt vegbaner har lenge blitt forurenset av partikler og giftstoffer fra vegtrafikken. I de senere år har fokus på makro- og mikroplastforurensning i naturen økt, herunder opptreden av mikroplast fra gummi i ... -
Kø-problematikken på Fv562 Askøybrua - Kø i morgenrushet fra Strusshamnvatnet til rundkjøring ved Storavatnet
(Master thesis, 2015)Det er store avviklingsproblemer rund Askøybrua på Fv562 i morgenrushet. Etter Askøybrua ble nedbetalt i 2006 og bompengeinnkrevingen opphørte økte trafikken betraktelig. Det ble også mer populært å bosette seg på Askøy. ... -
Laboratoriestudie av saltdiffusjon i kvikkleire
(Master thesis, 2012)Denne masteroppgaven er en laboratoriestudie på hvordan tilsetning av salt vil påvirke geotekniske og geokjemiske egenskaper i norske marine leirer (kvikkleirer) fra forskjellige steder. Endringen i leirenes oppførsel vil ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
(Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Laboratory Friction Testing of Cross-Country Skis: Experimental Investigation of Ski Design Parameters’ Effect on Friction
(Doctoral theses at NTNU;2024:331, Doctoral thesis, 2024)Cross-country skiing holds a significant place in Norway's cultural history as the national sport. It plays a crucial role both in public health as a recreational activity and as a highly competitive sport. A decisive ... -
Laboratory investigation of frost susceptibility of crushed rock aggregates and field assessment of frost heave and frost depth
(Doctoral theses at NTNU;2020:335, Doctoral thesis, 2020)In Nordic countries that experience seasonal frost, understanding how it affects the service life of linear transport infrastructures such as roads and railways is essential. Frost action both regroup frost heave and thaw ... -
Laboratory Investigation of Impact of Injection–Abstraction Rate and Groundwater Flow Velocity on Groundwater Heat Pump Performance
(Peer reviewed; Journal article, 2023)Using low-temperature (shallow) groundwater as a heat source or heat sink is a common practice to supply space heating or cooling, especially in the United States, Canada, China, and several European countries. The groundwater ... -
Laboratory investigation of performance of a screen type debris-flow countermeasure
(Journal article; Peer reviewed, 2018)Debris-flows are forms of landslides in mountainous regions that can potentially cause significant damage. Structural countermeasures to mitigate an entire debris-flow may become unrealistically massive and expensive. If ... -
Laboratory Investigation of the Pore Pressure Built-Up in Moving Debris
(Master thesis, 2015)Debris flow poses significant threat to property and human life mainly as a result of its high sediment concentrations and mobility. For the purpose of predicting debris flow mobility and mitigating potential damage, ... -
Laboratory Investigation on Development of Bitumen Exposed to Chemicals
(Doctoral theses at NTNU;2022:186, Doctoral thesis, 2022)As one of the most significant components of asphalt concrete, bitumen is crucial to the durability and lifespan of asphalt pavement. The asphalt pavement is exposed to different external conditions, such as traffic loading, ... -
Laboratory investigation on rejuvenating and self-healing properties of aged asphalt containing Ca-alginate capsules
(Doctoral theses at NTNU;2024:185, Doctoral thesis, 2024)The aging and cracking of asphalt pavement seriously affect the service life of asphalt pavement. Calcium alginate capsules have been shown to release a rejuvenator to repair cracks inside asphalt concrete under traffic ... -
