Airplane braking friction on dry snow, wet snow or slush contaminated runways
Klein-Paste, Alex (Journal article; Peer reviewed, 2018)Airplanes need tire-pavement friction during taxiing, take-off and landing. The presence of snow reduces the friction and therefore there is need to understand how much friction can be expected on the different types of ... -
Bicycle rolling resistance under winter conditions
Fenre, Mathis Dahl; Klein-Paste, Alex (Peer reviewed; Journal article, 2021)In many cold regions of the world, the percentage of trips made by bicycle drops drastically during the winter months. To facilitate increased bicycle usage during the winter, we studied the effect of typical winter ... -
Bruk av drone (RPAS) til vurdering av snøskred og steinsprang på veg
Hjellen, Odd Einar (Master thesis, 2016)For å bruke drone i Norge kreves det at man sender melding, eventuelt en søknad til Luftfartstilsynet og følger gjeldende regelverk tilknyttet til dette. I første del av oppgaven vil jeg ta for meg hvilket regelverk som ... -
Bruksverdien til frysepunktsensorer benyttet til vinterdrift på flyplass

Can calorimetry be used to measure the melting rate of deicers
Kulyakhtin, Sergey; Klein-Paste, Alex (Peer reviewed; Journal article, 2020)Chemical deicers are used in winter maintenance of roads and runways to melt ice and restore a bare pavement. The melting rate of these deicers is a fundamental performance factor, but good test methods to quantify the ... -
Can Sugar-Based Additives Increase the Longevity of a Salt Application for Anti-Compaction of Snow? Development of an Experimental Procedure
Vik, Therese Sæbø (Master thesis, 2020)I vintersesongen påføres det store mengder salt på vegbanen for å sikre trafikksikkerhet og god fremkommelighet på veiene. Salt blir påført på veien for å forhindre at vann fryser til is (anti-ising), forhindre snø fra å ... -
Challenges of integrated multi-infrastructure asset management: a review of pavement, sewer, and water distribution networks
Daulat, Shamsuddin; Rokstad, Marius Møller; Klein-Paste, Alex; Langeveld, Jeroen G.; Tscheikner-Gratl, Franz (Journal article; Peer reviewed, 2022)The prosperity of urban life is dependent on its infrastructure. Urban underground infrastructure components (assets) are aging and need regular monitoring, maintenance and rehabilitation. These assets are often placed ... -
Chemical Frost Protection of Road Surfaces: A Laboratory Investigation
Fjærestad, Janne Siren; Klein-Paste, Alex; Wåhlin, Johan (Peer reviewed; Journal article, 2020)Anti-icing chemicals are commonly used to protect against hoar frost formation on roadways and bridges. Because of their negative impact on both environment and infrastructure, their use should be optimized. During conditions ... -
Confronting the Challenges of Integrated Multi-infrastructure Asset Management
Daulat, Shamsuddin (Doctoral theses at NTNU;2024:232, Doctoral thesis, 2024)The well-being and economic prosperity of urban areas are tied to the effectiveness and reliability of their infrastructure systems. These systems are interdependent, influencing each other across various dimensions. ... -
Cycling Comfort on Different Winter Road Conditions
Kristensen, Håvard Eggen (Master thesis, 2019)Sykkeltransport har en rekke fordeler for samfunnet, men andelen sykkelreiser om vinteren synker i kalde regioner. Vinterføre på veiene fører til en rekke problemer for syklister, blant annet redusert sykkelkomfort. På ... -
Development of a Laboratory Abrasive Wear Test for Snowplow Cutter Blades
Rø, Ole Eftang (Master thesis, 2021)Prediksjon av slitasje som forekommer på slitestål montert på brøytebiler under snørydding gjøres per dags dato ved å måle mengden stål som slites bort mens brøytebilen er i drift. Eksisterende forskning har prøvd å ... -
Development of a Linear Tribometer
Fenre, Mathis Dahl (Master thesis, 2016)A mobile, linear tribometer for studying frictional characteristics on various materials gliding on snow and ice has been developed. The tribometer has the ability to adjust the normal force on the specimen to simulate ... -
Do We Need a Change in Road Winter Maintenance to Accommodate for Automated Vehicles? A State-of-the-Art Literature Review Considering Automated Vehicle Technology’s Usage of Road Infrastructure During Winter
Ødegård, Ingvild; Klein-Paste, Alex (Peer reviewed; Journal article, 2021)For automated vehicles to be allowed to join the modern car fleet, and, in the future, replace human drivers, they must be able to handle adverse weather, including snowy conditions. This literature review focuses on how ... -
Driftens betydning for synshemmedes mobilitet på vinterføre
