BOSTON (AP) – Logan International Airport will repave one of its runways with a new asphalt mix that is said to require less energy to produce and cuts down on greenhouse gas emissions.

The Massachusetts Port Authority board voted Thursday to approve the $6.3 million project, which will begin in the fall.

Massport officials say the so-called “warm mix” asphalt takes less energy to heat than traditional asphalt, saving some 200,000 gallons of diesel fuel. The new mix is expected to produce about 20 percent fewer greenhouse gases when applied.

The mixture will also contain up to 20 percent of recycled asphalt.
