CTB it is recommended to use soilaggregates that provide dense wellgraded blends with a nominal maximum size not to exceed 3 inches 75 mm in order to help minimize segregation and produce a smooth finished surface see Figure 21 Gapgraded soilaggregate mixes that are dominated by two or three sizes are not desirable for most CTB
The resilient modulus values increased with the increase in dry density and compaction level Also coarser LL provided higher M R values compared to finer UL because of increased aggregate interlocks For opengraded base layers permeability can increase due to the increase in angularity of aggregates even in the presence of fines

Jun 27 2017nbsp018332Unit weight is also commonly termed density The total unit weight is a function of the moisture content of the soil Table 58 Distinctions must be maintained between dry d saturated sat and moist or total t unit weights The moisture content should therefore be obtained at the same time as the unit weight to allow
Dense graded aggregate DGA also referred to as wellgraded aggregate or quarry process QP is stone that has been crushed through a series of crushers and screened through a sieve Although some individual stones in the mix are 1 189 in size the product is bound together with smaller sized stones stone particles and stone dust
Jul 30 2012nbsp018332After that weight the aggregate mass that is inside the container and divide it by the volume of container This will give you the bulk density of the loose aggregates Compacted Bulk Density Compacted bulk density can be determined by filling the container in three layers and tamped each layer with a 16mm diameter rounded nosed rod
For mixture proportioning the bulk unit weight aka bulk density is required The bulk density measures the volume that the graded aggregate will occupy in concrete including the solid aggregate particles and the voids between them Since the weight of the aggregate is dependent on the moisture content of the aggregate a constant
The maximum unit weight is sometimes called the solid density This value is based on the asphalt mixtures maximum specific gravity also known as the Rice value or G mm in Superpave The maximum unit weight is determined by multiplying the Rice value by 624 pounds per cubic foot PCF For example 2500 is a typical Rice value 2
