Cube operates and maintains two assets in the State of Rajasthan (Jaipur – Mahua and Mahua – Bharatpur). These assets experience heavy axle loads, high volume of commercial traffic and extreme temperature conditions (very hot in summers and cold in winters). Because of these conditions, despite using polymer modified bitumen, the pavements of these assets experience high distress and premature failures. To prevent this failure and enhance pavement life, Cube, for the first time for a Highway in India, considered Highly Modified Asphalt (HiMA) for overlaying a part of Jaipur – Mahua section.
Because of extremely high axle loads, Jaipur – Mahua and Mahua – Bharatpur Toll Road sections experience extensive rutting. To prevent this failure and enhance pavement life, Cube considered Stone Matrix Asphalt (SMA) for overlaying a part of Jaipur – Mahua section.
Stone Matrix Asphalt SMA
Conventional Hot Mix Asphalt HMA
LHS Carriageways of Jaipur – Mahua and Mahua – Bharatpur Toll Road sections predominantly carry empty vehicles and therefore low axle loads. Cube considered Fibre-reinforced Micro-surfacing for resurfacing LHS of both Jaipur – Mahua and Mahua – Bharatpur sections.
Functional Elastomeric Polymer (FEP) is a cellulose fiber pellets used for polymer modification of bitumen at site.
