Aashto Flexible Pavement Design Calculator

Higher SN means stronger pavement thus the impact of traffic on pavement deteriorations is less. 040 to 050 3.

Pavement Calculator Pavement Design Calculator Software

The AASHTO flexible pavement design spreadsheet automatically calculates the Structural Number of each layer and adds them together to get the total Structural Number of the pavement.

. Runs on the Windows NET platform. Please note that the structural coefficient of the base layer 034 is a function of its position within the pavement structure and not necessarily material properties. General The AASHO road test completed in the 1950s and subsequent AASHTO Guide for the Design of Pavement Structures AASHTO Design Guide provide the basis for current pavement design practices.

This tool calculates the total number of ESALs that have or will traverse a pavement for the purposes of pavement analysis or design. PaveXpress a web-based pavement scoping tool that simplifies the design of flexible and rigid pavements is also based on AASHTO 93. Flexible Pavement Several layers of composition.

Material properties for structural design a. 030 to 040 Flexible Pavements. Is the 18000 lb 80 kN equivalent single axle load ESAL.

The Provided SN depends on whether this is new construction or a rehabilitation. Using E 2as the M R value determine from Figure 1125 the structural number SN 1required to protect the base and compute the thickness of. Ad Search and Buy AASHTO Specs.

Pavement Interactive was developed by the Pavement Tools Consortium a partnership between several state DOTs the FHWA and the University of Washington as part of their effort to further develop and use computer-based pavement tools. So we must check if the final SN 3 is similar to the assumed SN. Topic 7 AASHTO Flexible Pavement Design 266 General Procedure 1.

The lower the overall deviation the better the equations model the data. Please note that the structural coefficient of the base layer 034 is a function of its position within the pavement structure and not necessarily material properties. Free online knowledge for the paving industry.

Solve the design equation for SN. Please see the AASHTO 1993 Pavement Design Guide for guidance on rehabilitation design as well as calculations for ESALs. Road Test data fits the AASHTO Design Equations.

The equivalent load most commonly used in pavement design in the US. 4872 Pavement Calculator Description Stand alone software version of the pavement design portion of the CE CALC website. Determine and gather flexible pavement design inputs Z R S o Δ PSI and M R.

There are some calculators online too. Required Equivalent 18 kip. Equivalent single axle load ESAL Design period ESALs.

The designer can instantly see the contribution of each layer making it easy to optimise the design by adjusting the thicknesses of each layer. CLICK HERE You may be interested in other topic HERE.

5F-1 Design Manual Chapter 5 - Roadway Design 5F - Pavement Thickness Design Pavement Thickness Design 1 Revised. The pavements which flexes and deflects under loading is known as flexible pavement it is made of several layers of material use this free engineering calculator to calculate exact measurements of flexible pavements. UFC design method - Calculate the maximum length of steel reinforced rigidconcrete pavement.

Designing Flexible pavements have many methods First of all you have to know that there are pavement design equations for both new and overlaid pavements based. Performs civil engineering calculations for trafficroad geometry surveyingearthwork pavement concrete floors and unit conversions. The standard method in the 1993 AASHTO Guide for Design of Pavement Structures involves calculating a weighted average subgrade resilient modulus based on the relative pavement damage.

Company-Wide AASHTO Codes Subscription Available. Because lower values of subgrade resilient modulus result in more pavement damage lower values of subgrade resilient modulus are weighted more heavily. The following ranges are recommended.

Estimate the traffic count for each load type for the entire design life of the pavement and multiply it by the calculated LEF to obtain the total number of ESALs expected over the design life of the pavement. However the coefficient can be changed in Step 4 of the design of a flexible pavement to match a recalibrated layer coefficient. In the AASHTO flexible pavement design traffic is considered in terms of ESAL for the terminal PSI Table 2013 for p t 25 We must assume the structural number of the pavement.
