#Flexible pavement design software full
Full – depth asphalt pavements are constructed by placing bituminous layers directly on the soil sub-grade. Two methods of flexible pavement structural design are common today: Empirical design and mechanistic empirical design.Ĭonventional flexible pavements are layered systems with high quality expensive materials are placed in the top where stresses are high, and low quality cheap materials are placed in lower layers. Bentley has developed MX Road and Open Road platform to provide the same services.
#Flexible pavement design software software
Autodesk has developed Civil 3D software as a design tool for highway design. Which is the best software for highway design? CIRCLY is widely used in Australia and overseas and is an integral part of the Austroads Pavement Design Guide. The program can calculate stresses, strains and displacements induced by a variety of surface loads on layered soil systems.
What is Circly?ĬIRCLY is a comprehensive program for analysis and design of pavements. The AASHTO method utilizes an index termed the “structural number” (SN) to indicate the required combined structural capacity of all pavement layers overlying the subgrade. The current AASHTO method is a regression method based on the results of road tests. What is the pavement design?Ī highway pavement is a structure consisting of superimposed layers of processed materials above the natural soil sub-grade, whose primary function is to distribute the applied vehicle loads to the sub-grade. WinPAS (roads, highways based on AASHTO 93 Method): JPCP JPCP Overlays. Which software is used for pavement design?ĪCPA offers a variety of concrete pavement and concrete overlay thickness design software, including: StreetPave (streets, roads, highways): JPCP JPCP Overlays.

Which software is best for road design?.Which software is used for pavement design?.The predictions from calibrated models show that the use of calibrated coefficients improves the accuracy of the pavement ME predictions and the design of flexible pavements in Oklahoma. The locally calibrated coefficients for the distress and IRI models for the Oklahoma pavement system were determined. The nationally calibrated models showed large errors and significant bias values, which asserts the need for local calibration. The predictions from distress and international roughness index (IRI) models were evaluated and compared with the measured distress values, and the accuracy and bias of each model were determined. The material input data were evaluated, and the most accurate available data was selected. This software can be used to process and compile the required pavement ME input data based on the Oklahoma material, traffic, and climate properties gathered from long term pavement performance and Oklahoma and national cooperative highway research program datasets. Also, to facilitate using Pavement ME, an interface software named INput ME was developed. In this study, the Pavement ME design prediction models were calibrated using local inputs and performance data for the state of Oklahoma. The existing performance prediction models utilized in this design guide are nationally calibrated, and it is essential to calibrate these models based on the specific regional materials and environmental conditions and pavement performance information. The AASHTOWare Pavement ME Design software was developed as an advanced pavement design tool based on the mechanistic-empirical pavement design guide (MEPDG).
