StreetPave Online utilizes new engineering analyses to provide recommendations for existing concrete pavements and new concrete pavement designs for city, municipal, county, and state roadways.

For both an existing and new pavement design, StreetPave will analyze your design constraints/requirements, pavement properties, and traffic characteristics. For existing concrete pavements, StreetPave will output the theoretical year in which the pavement will fail, along with the total erosion and fatigue that will occur over the user-specified design life. For a new concrete pavement analysis, StreetPave will output a design recommendation for concrete thickness, dowel bar use, and maximum transverse joint spacing.

Step 3: Input traffic characteristics


Traffic Category




Note: Based on your traffic category selection, StreetPave will automatically determine the likely axle load distribution scenario. If the actual axle load distribution differs, choose the user-defined option and fill-in the table below.

Step 4: Input pavement properties

Resilient Modulus

NOTE: Always use the Resilient Modulus of the untreated subgrade soil. If the subgrade soil is to be treated (or stabilized), include the treated soil as a separate subbase layer in the pavement structure. It is inappropriate to start with a treated or stabilized soil as the pavement subgrade.

You may either directly enter the MRSG value below, or use correlations to California Bearing Ratio (CBR) or Resistance Value (R-value) to estimate MRSG. StreetPave will calculate MRSG using your input.
