46 New Aci concrete pavement design For Trend Written by Paul · 7 min read. On the other hand parking lots differ from other pavements in that most of the area is intended for storage of vehicles and other goods rather than for movement of vehicles. NRMCA Local Paving Senior Director South Central Region 20 Years in Practice. 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. The basic design equation used to estimate the overlay thickness for a flexible pavement is as follows: = {(10 18−)+()+[ (𝑃 −) ]−( 𝐵−)} {[+( 5)]}.

NRMCA Local Paving Senior Director South Central Region 20 Years in Practice. PAVEMENT DESIGN Subbase Effects The current Design does not model the contribution of bases accurately. At the AASHO Road Test, it was found that the concrete pavements with granular bases could carry about 30% more traffic. The current design procedures allows concrete pavements built with granular bases to carry about 5 - 8% more traffic. The basic design equation used to estimate the overlay thickness for a flexible pavement is as follows: = {(10 18−)+()+[ (𝑃 −) ]−( 𝐵−)} {[+( 5)]}.

Additional information on procedures for concrete pavement preservation can also be found in Topic Page 5. Highway Design Manual. 29 ნოე. This Part covers the assessment of input parameters needed for design, design methods for flexible and rigid pavements and gives guidance on the.
