Abstract: The development of stiffness of stabilized materials with time is critical to the construction process, particularly in the case of recycling, where traffic is often required to return to the recycled road soon after construction. However, little information in this regard is available. A secondary problem is the difference in stiffness gain between different stabilizer types. Small field and laboratory investigations in which three sections of stabilized material using lime, CEM II B-V 32,5R and CEM V A (S-V) 32,5N were constructed, regularly monitored and tested over a period of 22 and 140 days respectively. The in situ stiffness was determined using a Lightweight Deflectometer (LWD) and a Portable Seismic Pavement Analyser (PSPA) on sections that were covered and prevented from drying as well as sections exposed to the air. The investigation thus also included the effects of drying and carbonation.
