Concrete Pavement Design Example

design of concrete pavement for city streets,following are the factors involved in the design process for concrete streets: 1. subgrades and subbases 2. concrete quality 3. street classification and traffic 4. geometric design 5. thickness design 6, jointing 7. construction specifications sub!wades and subbases unlike o~er paving materials, the structural strength of a concrete pavement is largely within the concrete itself.concrete pavement design basics: considerations, site,three common pavement designs are used for pavement construction: jointed plain concrete pavements (jpcp): the logical design for concrete pavement since it is a reliable method and a cost-effective way to complete the job. the majority of concrete pavements are designed to be jointed without reinforcements..
