Asphalt testing pilot project
Transportation and Works Minister Steve Crocker says it’ll be a while longer before serious data starts coming in from the province’s asphalt testing pilot project.
For the project, five areas of the Trans-Canada Highway between Foxtrap and Holyrood were paved using different types of liquid asphalt.
The project, which aims to determine which asphalt specifications best suit Newfoundland and Labrador’s climate and environment, started about a year ago, Crocker said.
“The engineering staff here in the department tell me that they really expect to start seeing differences and structural changes somewhere in the 24month range,” Crocker said.
The lifespan of asphalt varies and can be argued but typically is 12 to 15 years, he said.
“Right now, at one year in, we’ve looked at it a couple of times, but we’re not really getting any significant data from that yet,” Crocker said.
“It’ll be in the next, I guess, twoto three-year range we should really start to see the difference in the different mixes and the compactions that we used.”
