A sub base is the layer of aggregate which however for firm written quotations you are much better to fill Recycled subUsed mainly as a sub-base or drainage layer this is a cost effective alternative to primary limestone or granite when laying down haul roads building paths or patio sub-bases or drainage layers Recycled track ballast can be used to fill voids in the ground and is a great sub-base material For path construction it should be covered by

Subbase (pavement)

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 Type 1 Subbase – Materials ManIn comparative terms when capping is necessary it has a moisture content discipline why doesn't type 1? why is density not measured as in some of the special 6's fills Why can sources of type 1 be mixed? Does type 1 protect capping or subgrade from rain? This material breaks rules as you build a pavement it is a teenager getting away CHAPTER 6 ROAD CONSTRUCTION TECHNIQUESThis material can serve as a sediment filter strip and catch wall (see Section 6 3 1) however care should be taken that this material is not incorporated into the base of the fill Past road failures show that fill slope failures have been much more frequent than cut slope failures (70

Subbases and Subgrades for Concrete Foundations

A concrete surface is only as stable and level as its subgrade and subbase Weak subgrade and subbase layers can settle differently across the surface and cause cracks in the concrete Any concrete project needs at least a compacted soil subgrade layer A thick gravel subbase and base may also be required and are usually worth the effort Subgrades and Subbases for SlabsNov 22 2017The subbase according to ACI 302 1 "Guide to Concrete Floor and Slab Construction " is a layer on top of the subgrade of "compactible easy to trim granular fill that will remain stable and support construction traffic " In some cases a base layer is placed on top of the subbase A strong base for the upper road structure A strong base for the upper road structure When compacted these layers of frost-resistant materials conduct water away from the upper pavement layers reducing tensions very effectively at the same time Compacting a gravel base layer using a single-drum compactor from HAMM Typical Road Structure Cross Section It acts as a separating layer b/w subgrade and road base By this it prevent the two layers from mixing up b Characteristics of materials used in Sub Base The subgrade material should be clean and free from organic matter and should be able to be compacted by roller to form stable sub-base The material should have following characteristic
