A Laboratory Study on Brick Dust for GSB layer of
Granular Sub-Base (GSB) layer has become a significant current building practise of all national highway projects in India for pavements placed on weak subgrade. One of the issues in the road construction sector is the proposed strict criteria for GSB material and its non-availability owing to limited sources.For two-product crushed base course structures, the lower layer is usually more free-draining and coarser (with a max nominal size of 50mm or 75mm). 3.4.2 Select Granular Sub-Base (SGSB) Select Granular Sub-Base (SGSB) material typically consists of a 75mm-minus sand and/or gravel mixture that is either processed (screened and/or T01-15 Pavement Structure Design Guidelines Gov

stockpiled as 19 mm and 50 mm crusher run aggregates and are used as an alternate to pit run or quarried granular materials such as Granular A and B. No special equipment or procedures are required for the material handling. Crushed concrete replaces granular base, sub-base and backfull material from pits and quarries. Recycled AggregateMechanistically, this configuration provides a stronger reaction platform than unbound subgrades or sub- bases, allowing increased granular base compaction during construction, and it also has the potential to take advantage of the compressive stresses induced in the granular aggregate base owing to the presence of the stiff underlying layer.Chapter Three Granular Base and Subbase Construction

The Granular Sub Base (GSB) layers are used in the flexible pavements to provide a stress-transmitting medium to spread the surface wheel load to a large area so as to prevent the shear and consolidation deformations. The crusher dust used in the study is passing IS 425 micron sieve which is added in proportions till the criteria satisfies12 小时之前The sub-base layer is often the main load-bearing layer of a pavement. It is designed to evenly spread the load of the paving, and any traffic thereon, to the sub-grade below. A well-constructed sub-base will aid drainage and prevent settlement and channelisation the phenomenon common on cheap installations of block paving, where Sub-bases Pavingexpert
