Prof. Curran/Dr. SaundersFLEXIBLE PAVEMENT DESIGN AND COMPARISION OF ALTERNATIVEPAVEMENTS USING IRC 37-2012Executive SummaryPavement designs are able to happen in many forms considering the pavement uses. Comparingthe different is essential to ensure that the different design parameters are met according topavement use. This project will be able to offer comparison factors of the flexible pavementdesign with other alternative pavements (Jackson, Puccinelli & Mahoney, 2014). This will bedone through the use of Indian Roads Congress 37-2012, which is able to specify the designprocedures for the flexible roads based on the CBR values. The main finding should be able toindicate different CBR values. The use of the roads determines the requirement of the differentdesign parameters where CBR is the main design parameter for the flexible pavements.1.IntroductionPavements are classified in different categories according to the materials used. Major twopavement classifications are Asphalt (flexible) pavement and concrete (rigid) pavement. Theflexible pavements have different layers, which vary in width during the design period.Additionally, other pavement designs also has different layers but not as in the flexiblepavements. There are clear differences, which are attained and experienced when the design ofthese pavements is happening. The major layers include subgrade, sub-base, base and binder and/or surface (Kazda & Caves, 2015). Determining the different CBR values of the different layersis able to offer the main difference in the design of the pavements. The flexible pavements dodeflect upon loading and therefore the name. Each layer of the pavements is able to carry certainload, which they pass to the other below. Moreover, the rigid pavement has little deflect upon

This proposal will beable to define the procedure of analyzing different pavements options ion terms of their designand compare with the flexible pavements design. The IRC 37-2012 will offer the basis of theCBR for the subgrade and the effectiveness of this key experiment. Additionally, the design ofthe pavement will be based on th IIT PAVE.2.State-of-the-art/Literature ReviewThe designs of pavements have been critical to different economies. Different designparameters have to be treated differently to enhance their main aim. The use of the pavements setup the design procedure for the pavements (National research council (U.S.), et al., 2016). Thecombinations of the traffic factors and materials properties have been critical in defining thedifferences of the pavement designs. Treatments of the pavement materials, together with thelayer widths are critical parameters, which are attained in the designs. In India, there are differentclassifications of pavements, which are done by the categories of the pavements and theauthorities who manage them(National research council (U.S.), 2014b). Some of the keyclassification includes national Highways (NH), State Highways (SH),Major District Roads(MDR), Other District Roads (ODR) and Village Roads (VR). The pavements have differentwidths of the layers. Some of these classifications are able to consist of the flexible pavementswhile others may exist as rigid or semi rigid pavements.Moreover, there are different combinations of designs of traffic and material properties in thedesign of the pavements in order to meet the specific requirements of the pavements. Eachcombination is able to lead to different design thickness of the layers (Kazmee & Tutumluer,
