Extra widening of National Highway –Studies on Materials Testing

Abstract

The Government of India has decided to upgrade 6500 km length of existing 4- lane divided highways into Six-Lane divided carriageway under Phase-V of National Highway Development project (NHDP). The Project of " Six lane of Chilakaluripet - Nellore section of NH-5 from km 1182.802 to 1366.547 (length 183.620) in the state of Andhra Pradesh under NHDP Phase V has been executed as BOT (Toll) under phase V through Public Private Partnership (PPP) on Design-Build-Finance-Operate (DBFO) pattern. The Project Highway shall be widened/ developed to have 6-Lane dual carriageway with 1.5 m wide paved and 2.0 m earthen shoulders facilities for each carriageway having median width up to 4.5m. All the Major Bridges, Minor Bridges and Culverts in the corridor are also widened to match the new road and shall be conforming to 6-Lane road configuration. The proposed construction of road work will involve use of modern innovative techniques and modern construction practices based on trained and intuitive experience. All the Major and Minor Bridges and Culverts en route are also proposed to be widened. The engineering properties of the materials are studied and results are discussed.
