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.”
