IRC:SP:73-2015 42 SECTION - 5 PAVEMENT DESIGN 5.1 General 5.1.1 The design and construction of new pavement sections, and of strengthening measures (overlay) for the existing pavement shall be carried out in accordance with the criteria, standards and specifications given in this section. Where alternative specifications or materials are proposed to bring in innovation in design etc., provisions of paras 1.9 and 1.11 of this Manual shall apply. 5.1.2 Design of new pavement sections or widening and strengthening of existing pavements shall take in to account all relevant factors for assuring reliable performance that satisfies the specified minimum performance requirements. 5.1.3 The Concessionaire shall undertake the necessary soil, material and pavement investigations and traffic volume and axle load studies in accordance with the good industry practice for preparing detailed designs. 5.1.4 The materials, mixes and construction practice shall meet the requirements prescribed herein and MOSRTH Specifications/IRC Specifications. 5.1.5 Where problematic conditions such as expansive soils, swamps or marshes, flooding, poor drainage, frost susceptible areas etc. are found to exist, adequate measures shall be adopted to deal with such site conditions. 5.2 Type of Pavement 5.2.1 The type of pavement to be provided shall be specified in Schedule ‘B’. If nothing is specified the Concessionaire may adopt any type (flexible/rigid) of pavement structure for new construction and/or widening of existing carriageway. 5.2.2 Strengthening of the existing flexible pavement will be carried out by providing appropriate bituminous overlay, unless specified otherwise in Schedule 'B' of the Concession Agreement. 5.3 Method of Design - New Pavements 5.3.1 Method of Design of Flexible Pavement The new pavement shall be designed in accordance with the IRC:37. “Guidelines for the Design of Flexible Pavements”. 5.3.2 Method of Design of Rigid Pavement Rigid pavement shall be designed in accordance with the method prescribed in IRC:58. “Guidelines for the Design of Plain Jointed Rigid Pavements for Highways” or IRC:101 “Guidelines for design of Continuously reinforced Concrete Pavement”.
