Improvement in Properties of Subgrade Soil by Using Moorum and RBI Grade 81 B.M.Patil, K.A.Patil . Abstract- The life of road depends on strength of the subgrade soil and traffic density. The subgrade soil is not uniform throughout the alignment of the road.
and MDD with different percentages of sand and fly ash: Light compaction is done to determine the water content-dry density relation. The salient compaction characteristics such as maximum dry density (MDD) and optimum moisture content (OMC) of different sand-fly ash-lime composite are listed in Fig 1.
Compaction is the process of densification of soil by reducing air voids. The degree of compaction of a given soil is measured in terms of its dry density. The dry density is maximum at the optimum water content. A curve is drawn between the water content and the dry density to obtain the maximum ...
Feb 26, 2009· In India, we placed sand fill in 1000mm lifts and did compaction checks at three different levels in the lift and the compaction was fine (note that this was very clean river sand). I usually test the surface of a sand lift - if passes - then okay but if it is a bit low, I scrape out 75 to 100 mm and retest.

poorly graded sand with non-plastic and incompressible in nature (SP) with C u = 2.07and C c = 1.44. Compaction characteristics of Sand under modified Proctor test have OMC of 6% and MDD 1.82 g/cc. From the compaction curve it can be seen that Sand attains higher densities with less variation in moisture contents.
The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.The test is named in honor of Ralph R. Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil compaction.

Absolutely love this question. There are a few different parts to this question 1. Which soil type has a maximum dry density? Both Coarse grained and Fine grained show will show a peak at maximum dry density. Coarse will show high MDD and low OMC ...
compaction depends on the lift thickness, contact pressure, and soil moisture content. Most contractors get a feel for these figures, based on their local experience. If you are dealing with a contractor who has not previously worked in the area, you should be wary.

Mar 27, 2014· Top layer of sand and gravel remains loose in vibrating compaction. Therefore, in final pass the roller should move smoothly without vibration. Dry densities attained in field trials normally should be around MDD/ specified Relative Density as obtained from laboratory tests and should form the basis for specification and quality control.
MDD, which required only the determination of a soil's dry density at 9%(g/g) water content. Ring et al. (1962), using artificially mixed soils, examined simple relationships between OWC and MDD with plastic limit, liquid limit, fineness average, average particle size, and particles finer than 0.001 mm. They

Aug 27, 2018· The apparatus full of sand is placed on the hole and shutter is opened to fill the hole with sand. When the sand stops from further going in the hole, apparatus is removed. But in this process a heap of sand contained in the funnel would also accumulate on the hole whose weight should be subtracted to get the correct weight of sand in the hole.
Dry sand that has a carefully measured unit weight is allowed to run into the hole from a pre w eighed bottle. After the exact amount that fills the hole has run out, the bottle is re-t u r ned to the labora t o r y for re w eighing the re m a i n i n g sand. The difference in weight is the amount of sand …

fine sand is uniformly graded and pond ash is not well graded, though in particle size distribution they were very much parallel. 5. The standard proctor test indicates that MDD of fine sand increases with lime percentage. It can be due to interlocking of lime particles in voids of fine sand.
medium sand range the MDD values are on the higher side for mixes prepared with. sand in comparison to those of prepared with quarry dust, the reason may be angular.

Optimum moisture content/maximum dry density (OMC/MDD) – when placing soils as fill materials, it is important to achieve suitable compaction, primarily in order to reduce the susceptibility of a soil to settlement.The ability to attain acceptable levels of compaction is reliant on the moisture content of the soil being placed along with the compactive effort achievable from the plant used.
