Frost Depth Prediction for Highway Subgrade Soils

Relationships Between Normal Frost-Heaving Forces and Areas of Bearing Plates

Behavior of Expansive Soils in Western Canada

Pore Distribution and Permeability of Silty Clays
This investigation utilizes pore size distribution measurements to examine the relationship between permeability and compactive variables for laboratory compacted clayey silts. Closed-system...

Freezing and Cyclic Triaxial Behavior of Sands
Most analyses of the seismic response of natural sand deposits involve laboratory cyclic triaxial testing of undisturbed samples. However, obtaining undisturbed sand samples, transporting...

River Temperature Variation with Freezing and Storage
Water temperature in the northern part of the United States is significantly affected by the freezing phenomenon. Because of the freezing constraint on the variability of water temperature,...

An Unusual Case of Unsatisfactory Concrete Durability

A Correlation of N-Factors

Winter Concreting at the Sayano-Shushenskaya Hydro Project

Effects of Moisture and Freeze-Thaw on Rigid Thermal Insulations: A Laboratory Investigation

Heave of Silty Sands
Freezing tests were conducted at the University of Washington Periglacial Laboratories on predominantly quartz mineral silty sands at five different gradations, with a degree of fineness...

Stochastic Properties of Daily Temperature in Rivers
Some stochastic properties of the daily range of water temperature variations in rivers, most of which are located in the central part of the United States, were analyzed using data published...

Creep of Sand-Ice System
Unconfined uniaxial creep tests were conducted at —8.5°C on sand-ice samples with an average wet density of 124 pcf (1,986 kg/m³). The samples were 94% water saturated, on the average,...

Durability Tests on Some Aggregates for Concrete
The study examines the durability of Minnekahta limestone and Sioux quartzite used for concrete aggregates in South Dakota due to freezing and thawing. Vacuum saturated and dry specimens...

Turbulent Jets with Reversible Buoyancy
The results of the numerical analysis of turbulent warm water jets discharging into quiescent water at freezing temperature are summarized. Due to the peculiar variation of the density...

Pore Sizes and Strength of Compacted Clay
Pore size distributions, compaction characteristics, and undrained strength and deformation data were related in tests to molding water content and type of laboratory compaction. The soil...

Sediment Transport in Tidal River
Estuarine sedimentation is a subject of significant interest in the field of sedimentation. A sediment transport computation technique is developed for a tidal river with graded bed sediment...

Effect of Seepage Stream on Artificial Soil Freezing
A numerical technique is presented for predicting the two-dimensional transient temperature distribution in freezing or thawing wet soil. The technique is applied in estimating the influence...

Ripples on Underside of River Ice Covers
A mathematical model is developed to predict the occurrence and describe the properties and behavior of ice ripples that form on the underside of river ice-covers. The local rate of freezing...

Concrete-Polymer Composites
Investigations of concrete-polymer composites have indicated that remarkable improvements in the structural and durability properties of concrete can be obtained by monomer impregnation...
