No more limestone to be used on road surfaces
The National Works Agency (NWA) is seeking to assure that limestone aggregate is no longer being used on road surfaces amid renewed concerns that the material could be contributing to road crashes.
Yesterday, the president of the Incorporated Masterbuilders Association of Jamaica, Carvel Stewart, raised concern about the safety of the Montego Bay to Ocho Rios leg of the North Coast Highway after four foreigners died in an accident along the thoroughfare early Sunday morning.
According to Stewart, the limestone aggregate used to construct the road is not hard enough and has resulted in a phenomenon known as polishing.
He says this causes the roadway to become extremely slippery.
However, communication and customer services manager at the NWA, Stephen Shaw, says the roadway met safety specifications at the time it was constructed.
However, he says the NWA has moved away from the use of limestone in asphaltic mix since that highway was completed about 10 years ago:
Meanwhile, head of the police traffic division has conceded that more signs are needed along the roadway to warn motorists.
However, he says the police are still investigating the cause of Sunday morning’s accident.
