U.S. 40, INDIANA'S FIRST HOT MIX RECYCLE PROJECT

This presentation reviews some of the findings of the project so far. Recycling offers a means to restructure asphalt pavements, correct for aggregate gradation and strength deficiencies, eliminate reflective cracking by removing the old material, and restore curb height eliminating drainage problems. Proper selection of asphalt rejuvenators can restore the properties of aged asphalt. Use of asphalt emulsion rejuvenators can reduce heat related problems in hot mix production, both in the dryer damage and heating effects on the bitumen. The use of RAP in recycling is economical, on this contract the contractor paid the Department of Highways $8.06 per ton for the RAP, when recycling is done at 50/50 this is a savings of $4.03 per ton of mixture.
