HOT IN-PLACE RECYCLING ADDS 15 YEARS TO ASPHALT'S LIFE

Tampa, Florida, is extending the life of its asphalt streets by hot-recycling worn-out pavements in place. Recycling in place is an economically attractive option where environmental distress is the primary factor in pavement deterioration, i.e., where there are signs of joint reflection cracking, block cracking, or longitudinal and transverse cracking, or where weathering and raveling are apparent. A Cutler R-2000 hot-recycler, purchased in 1986, has become an integral part of the city's street maintenance program. With it the city can recycle asphalt streets in-place for about $1/sq yd. Adding an overlay of 1/2 in. virgin hotmix increases that cost to about $2.31/sq yd and is expected to extend the life of roadways as much as 10 to 15 years. This article provides details of the recycling operation.
