One year performance evaluation of low volume road with cold recycled base course on the basis of FWD and Dynamic Modulus tests

Article presents results of assessment of performance of trial section of flexible pavement with cold recycled base constructed on low volume road within typical contract conditions. Performance evaluation was made based on Falling Weight Deflectometer (FWD) test performed during construction stage – 2 times on the top of cold recycled base course – 28 and 180 days after compaction of base course and 2 times on the top of the wearing course – 270 and 360 days after compaction of base course. Deflections and back calculated moduli were analyzed. Additionally, performance of the cold recycled base was determined on the basis of Dynamic Modulus test conducted on the material col-lected during trial section construction. Moduli were determined for 7, 14, 28, 90, 180 and 360 days after the specimen compaction. Performed analysis showed that the development of rheological properties shows similar trends for both field and laboratory tests and proved high bearing capacity of pavements with cold recycled bases.
