Assessment of the Tube Suction Test for Identifying Non-Frost-Susceptible Soils Stabilized with Cement
… used to mitigate the effects of frost heave. The tube suction test (TST) is one possible method for determining the frost susceptibility of soils in the laboratory. The purpose of this research was to assess the utility of the TST for identifying non-frost-susceptible (NFS) materials stabilized …

Evaluation of Laboratory Durability Tests for Stabilized Aggregate Base Materials
… test, the vacuum saturation test, and the tube suction test. Analyses of the test results indicated that the unconfined compressive strength (UCS) and retained UCS were higher for specimens tested in freeze-thaw cycling than the corresponding values associated with vacuum saturation …

Evaluation of Laboratory Durability Tests for Stabilized Subgrade Soils
… test, the vacuum saturation test, and the tube suction test. On average, to achieve the same 7-day unconfined compressive strength (UCS) values, the sand required 4.4 times more Class C fly ash than cement, 3.6 times more lime-fly ash than cement, and 6.0 times more lime than cement. …

Laboratory Comparison of Full Depth Reclamation Stabilization Techniques Using Arkansas Field Materials
… cement stabilized samples were tested using the tube suction test and the semi-circular bend test. Results indicated dynamic modulus is a viable testing indicator for rutting and low temperature cracking, while creep compliance may not be suitable for FDR materials. The semi-circular bend test …

Characterization of Recycled Concrete for use as Pavement Base Material
… a moisture susceptibility rating of good in the tube suction test, while the haul-back material was rated as marginal. Both materials exhibited self-cementing effects that led to approximately 180 percent increases in UCS over a 7-day curing period. Seven-day UCS values were 1260 kPa and 1820 kPa …

Effects of Reclaimed Asphalt Pavement on Mechanical Properties of Base Materials
… test was used to measure stiffness, and the tube suction test (TST) was used to measure moisture susceptibility. Once all the testing was completed, a fixed effects analysis of variance (ANOVA) was performed on each of the test results, or dependent variables. The independent variables were …

Identification and Stabilization of Problematic Silts
Silty soils are a common occurrence and can exhibit low strengths, and minimal bearing capacity, causing widespread construction and performance problems. These soils are highly moisture-sensitive and their stability is greatly influenced by the degree of densification achieved during compaction. …

Cement Stabilization of Aggregate Base Materials Blended with Reclaimed Asphalt Pavement
… strength (UCS) and final dielectric value in the Tube Suction Test (TST) were measured in a full-factorial experimental design including five RAP contents, five cement contents, and three replicate specimens of each possible treatment. Specimen mixtures consisted of 0, 25, 50, 75, or 100 percent …

Development of a Frost Heave Test Apparatus
Frost heave damage to roadways costs millions of dollars every year. The need for an improved understanding of the fundamental mechanisms associated with frost heave and methods for efficiently improving frost-susceptible materials prompted the Department of Civil and Environmental Engineering at …
