Natural sand and crushed stone are both used regularly in construction. The use depends on specification standards and economic considerations. In the production of portland cement concrete alluvial gravel is typically preferred. The rounded particles result in a wet mix that is easier to work,
Design of Concrete Pavement for City Streets
a concrete pavement is largely within the concrete itself due to its rigid nature, Because of the remarkable beam strength of concrete, heavy loads are distributed over large areas resulting in very low pressures on the subgrade. This makes it economically impractical to build up subgrade strength with thick layers of crushed stone or gravel.Paver base - Wikipedia,Paver base is a form of aggregate used in the construction of patios and walkways whose topmost layer consists of mortarless (or "dry-laid") pavers.The first layer in the construction of such a surface is called the subgrade-- this is the layer of native material underneath the intended surface.It is usually compacted and stabilized. If the final pavement is to have vehicle traffic, aHOT MIX ASPHALT PAVEMENT DESIGN GUIDE,principal types being crushed stone,sand,gravel,bank run gravel,roofing shingles and recycled asphalt pavement.

The concrete used for pavements can be modified and changed in various ways as per the requirement. Not only does the concrete pavement need to be strong and durable but
» Parking Lot Design
Minimum pavement thickness designs are given for both small parking areas (50 passenger car stalls or less) and larger facilities (over 50 passenger car stalls).

Rev. Stat. § 81-847 (Reissue 1996).Custom Stone Paver Designs & Hardscaping Services |,Concrete pavers resist deterioration from freezing and thawing cycles better than asphalt and ordinary poured in place concrete. De-icing products, such as calcium chloride or salt, will not harm the pavers either, making them a great choice for cold climates.Sub-bases | Pavingexpert,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 two 'ruts' develop in the paving.Aggregates - Portland Cement Association,Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the,Standard Specifications for Roads and Structures,For general questions about this publication, please contact the Contract Standards and Development Unit at [email protected] or (919) 707-6900.
