Mixing Efficiency of Recycled Asphalt Paving Mixtures
This report covers an extensive evaluation of a range of ideas for measuring the degree of mixing during the recycling of old asphalt pavements. The practice of using small amounts of rejuvenating or recycling agents is coupled with the problem of quality control. No suitable method exists that permits detecting how well the recycling agent (or, in some cases, virgin asphalt) mixes with the aged pavement materials. Usual quality control tests such as extracting and measuring the binder content and properties are not appropriate since these tests made the presence of recycling agents and extent of mixing. The project was aimed at development of a test method that could be conducted in the field with a minimum of equipment and training. Among the more traditional tests, the resilient modulus (MR) was found to be most suitable for physical testing of the recycled mixtures. The method might be used to determine the relative quantity of recycling agent used, since it is sensitive to small changes. However, a quick test for measuring the efficiency of mixing, it shows little promise.
