Influence of test specimen compaction and curing condition for pavement cold recycled mixtures

Popis výsledku v původním jazyce

Presently in most European countries the quality of cold recycling mixtures is proven by achieving required strength values (indirect tensile strength or compressive strength) and eventually by values of stiffness modulus (IT-CY test method). This empirical approach of quality assessment is quite simple, relatively fast in performance and set in the long term, but on the other hand it has some distinctive weaknesses. Foremost strong dependence of magnitude of received strength values on various factors,whereas one of the most important is the way how test specimens are prepared and compacted. Technical specifications in various European countries specify specimen preparation by using different laboratory equipment, which compact the test specimen by static pressure, dynamic hits or gyratory motion. Parameters of specimen compacting influence the resulting mix voids content as well as the resulting strength and stiffness modulus. Second important parameter is influence of test specimen
