  • Open-Textured Soil Or Granular Material Surface Preparation - Pavement InteractiveSurface preparation generally takes one of two forms:Preparing the subgrade and granular base course for new pavement. This can involve such activities as subgrade stabilization, over-excavation of poor subgrade, applying a prime coat or compacting the subgrade. Porous surfacing options - SusdrainPorous surfacing options Open-textured soil or granular material. Gravel or similar surface on a sub-base. Typically used in locations where very low volumes of light weight traffic, such as cars, will be present and a low cost solution is required.

    SOME ASPECTS OF UPSIDE-DOWN PAVEMENT DESIGN

    The upside-down design, consisting of a thin bituminous surfacing and an untreated granular base overlying a cement-treated sub-base, is discussed in this paper. The inter-dependence between the thicknesses of the three materials and the response to overloaded wheels were analysed with a computer program capable of stress-modulus iteration, PSAD2A. Section 6F-1 - Pavement Subbase Design and ConstructionMar 06, 2020 · section will deal with the proper design and construction of subbases. The subbase is the layer of aggregate material that lies immediately below the pavement and usually consists of crushed aggregate or gravel or recycled materials (see Section 6C-1 - Pavement Systems for more information).

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 two 'ruts' develop in the paving.
