CONSTRUCTION OF A RECYCLED BITUMINOUS PAVEMENT USING FOAMED ASPHALT

This paper discusses the construction of a recycled layer using foamed asphalt with the cold process in Indiana. Foamed asphalt seems to be an acceptable binder in cold recycling. No major equipment changes had to be made during construction to accommodate the foamed asphalt. The construction procedure could also be kept simple and progress maintained at an acceptable rate. The pavement could be opened to traffic soon after construction and it performed well. Even the heavy construction vehicles had no detrimental effect on the recycled layer. The importance of the correct moisture content during compaction and the detrimental effect of water on the recycled material must be kept in mind in design and construction. The initial and short term performance of this foamed asphalt recycled layer seems to be satisfactory. Results from tests show that there is reason to believe that it will behave well in the future, but, as mentioned in the introduction, this can only be verified through monitoring the future and ultimate performance in actual use.
