Demand elasticity of traffic with respect to macro-economic (r) estimated by studying and analyzing the following data:ī. The present day traffic has to be projected for the end of design life at growth rates Guidelines for New Flexible Pavement Design Thickness of GSB and WMM layers are maintained in such a way that in each andĮvery case the thickness adopted are in harmony with the adjacent plates. Pavement thickness plates are prepared assuming the plates given in IRC 37-2012 as theīasis. Given in the IRC: 37-2012 shall be adopted. For these methods, design plates and recommendations Recommends the use of bound sub-base, bound base and Recycled asphalt pavement layersfor economical pavement design. Relevant codes / MORTH specifications shall be referred.ĭesign plates are given for the unbound sub-base and unbound base layers. Involved in the design have been discussed briefly. The guidelines are prepared to make the pavement design easy and simple. Accordingly, design guideline for flexible pavementĭesign, design plates for CBR 3 to 15 and guidelines for overlay design has been prepared. These circumstances, the need for simplified design procedure and design plates for CBR Hence, henceforth, flexible pavement shall only be designed as per IRC: 37 2012.

In IRC: 37-2012, several changes were made in the flexible pavement design parameters. Tentative Guidelines for the design of flexible pavements during January 2013. Indian Roads Congress recently revised the existingįlexible pavement design IRC: 37-2001 and published the new guidelines IRC: 37 2012 In order to attain economical design and better performance, Indian Roads Congress revises Pavements are designed as per guidelines published by Indian Roads Congress, New Delhi.
