Weight Of Subbase Materials

In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. Subbase is often the main load-bearing layer of the pavement.Its role is to spread the load evenly over the subgrade.

For the first time in my life I am measuring densities of compacted type 1 subbase, we are using type 1 as an import backfill material on the Shetlands gas plant. It’s 4.5kg (method 3.5 BS 1377)dry density compaction is 2.38T/M3, it is a metamorphic rock whose relative density will be between 2.8/2.9T/M3 and we are achieving densities of 2.26 to 2.4T/M3.

05-05-2019· Subbase materials preferably might consist of naturally occurring, coarse-grained soils or blended and processed soils. When possible, avoid using materials which have more than 15 percent fines. Lift thickness is dependent on the type of material, the compaction equipment used, and the method of construction.

The mass of over 300 different 'dry' materials are listed below.

30-11-2018· 4. Subbase for Concrete Slab. Subbase is a layer of gravel, which is fairly cheap material, placed on top of subgrade. The subbase placement is optional and it serves as a work platform for construction of the slab and provide more uniform support for the slab. As the thickness of subbase increases, the ultimate load carrying capacity of slab ...

The sub-base material should be spread out in layers no thicker than 150mm and roughly levelled with spades, rakes or similar. Where a sub-base needs to be greater than 150mm in depth, it should be built-up as a series of layers, each being 150mm or less and thoroughly compacted before placing, levelling and compacting the next.

In the first constructions, granular materials were used in base layers and subbase layers on a large scale. As a consequence, they are no longer so widely available. However, with time and experience, professionals in this field noticed that other materials that were very common in some regions of the country, could be used.

Our Sub Base and Road Base has high specific gravity and is durable and sound. Due to the high CBR value this material has an added advantage in the pavement design and helps reduce the pavement thickness. Our Wet Mix is produced in an automatic controlled mixing plant with total control of moistures.

Hence, where a specified material is not available at the time of construction or within the region, it may be substituted by a higher Traffic Category material, or a Subbase material may be substituted by a Base material. However, higher standard materials can be expected to be more expensive.
