The quality of sub-base is very important for the useful life of the road and can outlive the life of the surface, which can be scrapped off and after checking that the sub-base is still in good condition, a new layer can be applied.
Road Base – Before roads and highways can be paved and be strong enough to withstand traffic, their bases must be filled with a reliable aggregate material. Limestone that has been crushed down to size is ideal as it's affordable, reliable and offers a smooth and easy ride.
2004-12-16· Turns out there is not much difference in price between slag, crushed concrete and limestone. There is a noticable difference in price between delivery methods ~$15/ton delivered with a 25 ton 3 axle but only ~$12 per ton for a double trailer road train that carries 50 tons a trip.
The most common uses for the material to be used without a binder are as a road base or sub-base material, shoreline riprap and railroad track ballast track beds, while it is most often used with a binder for cement and bituminous concrete (asphalt/blacktop) in road construction and repair as well as macadam roads and other general construction projects. Angular stone is the key material for ...
In March 1995, the City of Los Angeles passed a motion requiring that road base in all city projects include "crushed miscellaneous base" (CMB) with 100 percent recycled asphalt, concrete, and other inerts, except when site conditions or standards require another specification."
Recycled Aggregate. In March 1995, the City of Los Angeles passed a motion requiring that road base in all city projects include "crushed miscellaneous base" (CMB) with 100 percent recycled asphalt, concrete, and other inerts, except when site conditions or standards require another specification."

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.
Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in
Graded road base - on its own or blended with other slags and/or with other natural rocks and sands. Crushed and graded - for concrete aggregates, concrete sand, glass insulation wool, filter medium, and use under concrete slabs as a platform
Steel slag can be used as aggregate in granular base applications. It is considered by many specifying agencies to be a conventional aggregate and can normally exceed the aggregate requirements for granular aggregate base. The high bearing capacity of steel slag …
Sub-base – The sub-base is the bottom layer of crushed stone that sits on top of the sub-grade. This layer is comprised of larger crushed stone aggregate and helps to provide structural strength and integrity for the driveway.
Iron and steel slag used in road construction is manufactured by crushing and mechanical stabilization of blast furnace slag and steelmaking slag for use as paving material. These two types of slag are used in base course materials that are produced from them individually or in a mixture, and steelmaking slag is used as an aggregate for asphalt mixtures. Research into the use of iron and steel ...
Road surfacing gravel needs to be able to hold itself together to fight the effects of water and traffic. It requires binder, in the form of particles of silt and clay to fill the voids between the larger aggregates and act as a sort of cement. Surface gravel should not allow water to pass through it into the base. Instead, it should shed water to the ditches because of its shape.

PROPERTIES OF STABILIZED BLAST FURNACE SLAG ROAD BASE … Blast furnace slag, either crushed in situ or as plant crushed graded macadam, has become increasingly important as a base or sub-base on heavily trafficked roads in the Newcastle, Sydney, Wollongong region.
The splitting strength and resilience modulus of steel slag–fly ash–phosphogypsum were equivalent or superior to those of those typical road materials, The engineering of steel slag–fly ash–phosphogypsum solidified material as road base material should be an alternative approach to massively reuse those three solid wastes.
