Establishment of Intrinsic Permeability of Coarse Open-Graded Materials: Review and Analysis of Existing Data from Natural Air Convection Tests
Rieksts, Karlis; Hoff, Inge; Scibilia, Elena; Côté, Jean (Peer reviewed; Journal article, 2020)This paper presents a review and analysis of large-scale air convection tests and the establishment of intrinsic permeability in coarse open-graded materials. Natural air convection can make a significant contribution to ... -
Experimental study on the effect of soil moisture content on critical temperature rise for typical cable backfill materials
Rieksts, Karlis; Eberg, Espen (Peer reviewed; Journal article, 2022)The increased utilization of power grid requires operating power cables close to their thermal limit. Buried power cables in such condition experience thermal instability where thermal resistance increases as the moisture ... -
Heat Transfer Characteristics of Crushed Rock and Lightweight Aggregate Materials
Rieksts, Karlis (Doctoral theses at NTNU;2018:228, Doctoral thesis, 2018)Over the last decades there has been a major transition to using crushed rock materials for road and railway construction instead of natural materials such as sand or gravel. In addition, it is common practice to use very ...
