The 200 damaged pavers, to be paid for by Launceston City Council and a private operator, were part of an initial trial of materials for the council's City Heart project.

Launceston City Council general manager Robert Dobrzynski said the infrastructure was damaged by heavy garbage trucks, and they were now "seeking the operation of more appropriate vehicles for the CBD".

Mr Dobrzynski said the council intended to use trafficable pavers in its Quadrant Mall facelift, to prevent damage in any instance where emergency vehicles were required to enter the area.

He said the Centreway Lane repaving, and subsequent outcomes of the project, allowed the council to plan for larger scale initiatives as part of the Launceston City Heart Project.

"We used different bases in the construction, including mortar bases, which are commonly used in Europe, and a more traditional sand base," Mr Dobrzynski said.

"We have also conducted multi-week technical trials of different pavers and bases under regular heavy vehicle loads at the Council's Remount Road depot."

He said trials provided the council with knowledge about the effectiveness of paver patterns, choices, bases and other technical details.
