IRC:SP:73-2015 42SECTION - 5PAVEMENT DESIGN5.1 General5.1.1The design and construction of new pavement sections, and of strengthening measures (overlay) for the existing pavement shall be carried out in accordance with thecriteria, standards and specifications given in this section. Where alternative specifications ormaterials are proposed to bring in innovation in design etc., provisions of paras 1.9 and 1.11 of this Manual shall apply.5.1.2Design 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.5.1.3The Concessionaire shall undertake the necessary soil, material and pavement investigations and traffic volume and axle load studies in accordance with the good industrypractice for preparing detailed designs.5.1.4The materials, mixes and construction practice shall meet the requirements prescribed herein and MOSRTH Specifications/IRC Specifications.5.1.5Where problematic conditions such as expansive soils, swamps or marshes, flooding, poor drainage, frost susceptible areas etc. are found to exist, adequate measuresshall be adopted to deal with such site conditions.5.2 Type of Pavement5.2.1The type of pavement to be provided shall be specified in Schedule ‘B’. If nothingis specified the Concessionaire may adopt any type (flexible/rigid) of pavement structure fornew construction and/or widening of existing carriageway. 5.2.2Strengthening of the existing flexible pavement will be carried out by providingappropriate bituminous overlay, unless specified otherwise in Schedule 'B' of the ConcessionAgreement.5.3 Method of Design - New Pavements5.3.1Method of Design of Flexible PavementThe new pavement shall be designed in accordance with the IRC:37. “Guidelines for the Design of Flexible Pavements”.5.3.2Method of Design of Rigid PavementRigid 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”.
IRC:SP:73-2015435.4 Design Requirements for New Pavement Sections5.4.1Flexible Pavement - Design Period and Strategyi)Flexible pavement shall be designed for a minimum design period of 15years, subject to the condition that design traffic shall not be less than 20msa. . ii)Stage construction shall not be permitted.5.4.2Rigid Pavement-Design Period and StrategyRigid pavement shall be designed for a minimum design period of 30 years. The stage construction shall not be permitted.5.4.3Pavement performance requirements for main carriageway, service roads, entry/exit ramps and acceleration/deceleration lanes shall be follows :i)The pavement structure shall be capable of giving the specified performanceover the entire operation period.
