Investigation of the Geotechnical Properties of Municipal Solid Waste as a Function of Placement Conditions
… and presence of compressible solids. Control of moisture content of MSW at the time of waste placement provides opportunity for increased capacity at a given landfill site due to higher compacted unit weight as well as for control of other geotechnical properties. A laboratory experimental test …

Evaluation of the electrical density gauge for in-situ moisture and density determination
… densities normally achieved at specific moisture contents for a given compactive 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 …

The suitability of rammed earth for construction in the Cape Town metropolitan area
… to assess soil grading, organic matter content, plasticity and Optimum Moisture Content (OMC). Grading gave an indication of fines present and plasticity indicated the cohesive nature of the fines. More detailed tests were undertaken to determine type and level of soluble salts and …

Strength and Erodability of South Carolina Soils for Embankment Construction
… 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 (ML) and D1-Richland-08, …

Engineering Performance of Polymer Amended Soils
… types; amendment types and addition rates; and moisture contents to enhance understanding of the engineering significance of polymer amendment. Four soils were manufactured and tested with varying ranges of fines and plasticity. A proprietary elastic copolymer was tested at addition rates of …

Enhanced Biodegradation in Landfills
… properties. These parameters of interest were moisture content, pH, density, temperature, volatile solids, cellulose/lignin ratios, and biological methane potential (BMP). Leachate recirculation increased the dry density 55% faster and decreased the BMP 125% more rapidly. Moisture content was …

Adapting The Modified Cam Clay Constitutive Model To The Computational Analysis Of Dense Granular Soils
… up to 95% of maximum unit weight at the optimum moisture content. Each soil sample was tested using different stress paths. In addition, these data were also used to obtain the soil parameters. These soil parameters are used as input data for the Modified Cam Clay Model. Moreover, a …

Influence of subgrade improvement and non-uniformity on pavement performance
… layer for road construction. The measured moisture-density curves for manufactured sand and limestone screenings are about the same, and the moisture-strength curves show a dramatic decrease in strength beyond the optimum moisture content for strength. Durability testing concluded that CKD …

Durabilidade e módulo de elasticidade de misturas areia - cal - cinza volante
… ash and 4% lime. The second mixture had the same contents of lime, fly ash and dune sand, but having 1% of high initial strength portland cement as additive. The third mixture had 53% dune sand, 30% crushed stone, 4% lime,13% fly ash and 1% of high initial strength portland cement as additive. All …

Evaluation of Moisture, Suction Effects and Durability Performance of Lime Stabilized Clayey Subgrade Soils
… laboratory study is undertaken to evaluate the moisture, suction effects and durability performance on resilient modulus (MR) and unconfined compressive strength (UCS) of lime treated clayey subgrade soils. Two subgrade soils: the AASHTO class A-6 and A-7-6 are collected from US 491 road site in …

Ground improvement using PET bottle waste as a potential reinforcement material for granular columns: an experimental approach
… a local fine silt. A wet silt bed (prepared at optimum moisture content or liquid limit) was created within a steel cylindrical tank. An ordinary granular column (OGC) or reinforced granular column (RGC) was then installed within the tank and a compressive vertical load was applied to the …

Effects of Reclaimed Asphalt Pavement on Mechanical Properties of Base Materials
… Two sources of RAP, two sources of base, and RAP contents of 0, 25, 50, 75, and 100 percent were utilized in a full-factorial experimental design with three replicates of each unique combination. Testing procedures consisted of material classifications, compaction tests, and evaluations of …

Stabilisation of clay subgrade soils using ground granulated blastfurnace slag
… clays suffer volume change due to changes in moisture content which causes heaving, cracking and the break up of the road pavement. Stabilisation of these types of soil is necessary to suppress swelling and increase the strength of the soil and thus partially decrease the thickness of road …
