Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro
… a laboratory compaction test to determine the maximum dry density of compacted soils, which can be used for specifications of field compaction. The Compaction of soils is influenced by many factors, the most common are the moisture content, the soil type and the applied compaction energy. The …

Factors influencing laboratory vibratory compaction
… tests exist for the determination of the maximum dry density of cohesionless, free-draining soil. The US methods are based on the use of a vibratory table, while the European practice is based on the use of a vibratory tamper. No standard tests appear to exist for soil exhibiting cohesion, …

Strength and Erodability of South Carolina Soils for Embankment Construction
… All of the specimens were remolded to 95% of the maximum dry density with moisture content between -1% to +2% of the optimum moisture content. Based on the results, soils from D2-Anderson-01, B-1 (MH), D2-Abbeville-01, B-1 (SM), D4-York-04, B-2 (SM), D2- Abbeville-01, B-3 (SM), D1-Richland-08, B-2 …

Investigating Use of Aggregate Density to Develop Design Aggregate Structure for Asphalt Concrete Mixtures
… potential causes for the failures, aggregate density within the mix when designed at 80 gyrations was of specific concern to this thesis and was compared to the maximum dry density of the aggregate as measured using ASTM D4253-00. The objective of this research was to determine if the …

Geoenvironmental aspects of coal refuse-fly ash blends
… indicated that, with increasing fly ash, the maximum dry density of these blends marginally decreased. The permeability test results showed that the permeability of the test specimens progressively decreased with the increase in fly ash. The shear strength results demonstrated that the …

Contractor Variability in Construction of Cement Treated Base Layers
… time between mixing and compaction in the field, dry density in the field, 7-day dry density, 7-day moisture content, 28-day dry density, and 28-day moisture content. The factors that were found to be the most variable on both I-84 and US-91 were CBR, cement content, time between mixing and …

Evaluation of the electrical density gauge for in-situ moisture and density determination
… effort. The optimum moisture content and maximum dry density for a particular soil is determined by means of Proctor tests in the laboratory. A relative compaction index is then used to correlate the laboratory values with the field compaction values obtained using in-situ tests. The Sand …

Stabilisation of clay subgrade soils using ground granulated blastfurnace slag
… carried out. Various mixes (up to 10% GGBS by dry weight of the test soil and up to 30% replacement by hydrated lime) were prepared and cured under two representative conditions {20°C with 90-100% relative humidity (CCI) and 35° C with 50-60% relative humidity (CC2)} for up to 12 months. …

Soil stabilization utilising wastepaper sludge ash
… reduced the plasticity index (PI), reduced the maximum dry density (MDD) and increased the optimum moisture content (OMC) of both LOG and Kaolinite. The UCS values of stabilized systems incorporating WSA for both LOG and Kaolinite were higher than those systems stabilized with the traditional …

Cement Stabilization of Aggregate Base Materials Blended with Reclaimed Asphalt Pavement
… materials were between 5.6 and 6.6 percent, and maximum dry density (MDD) values were between 129.7 and 135.5 lb/ft3. In both cases, decreasing values were associated with increasing RAP contents. The results of the ANOVA performed on the UCS data indicate that UCS decreases from 425 to 208 psi …

Development of technology for the construction of low-cost road embankments
… using a static compaction apparatus to achieve Maximum Dry Density (MDD). Depending on the testing regime to be applied to a given specimen, a curing pattern was defined and samples were wrapped in cling film to minimise moisture losses. At the end of each curing period of 7, 14, 28, 56 and 90 …
