Rock tests for highway

MOST rock aggregates found on Vanua Levu do not meet the specifications of the Australian engineering standards for road sealing purposes.

Speaking during a media tour of China Railway First Group's project site between Dreketi-Nabouwalu yesterday, project engineer Jeff Peng said they had to carry out improvements on rocks so it could be used for the road sealing program.

Mr Peng said since hiring OPUS International consultancy group from New Zealand for advice, they had been informed that most rocks exceeded the standard plastic index specification for road sealing purposes.

"The perfect specified standard liquid limit for rocks in such engineering projects is 25 but most rocks found on the island exceed these levels and they are not perfect for road sealing purposes.

"The liquid limit refers to the amount of moisture found in rocks and those with high levels of liquid are not perfect for road construction.

"But, we have identified some rocks that do not meet the required specifications but could perform with some alterations and this includes rocks and pebbles found in rivers."
