Use of reclaimed asphalt pavement (RAP) in warm mix

Apr 10,  · The limit in the use of reclaimed asphalt pavement material (RAP) proportion is restricted due to stiffness and workability issues related to RAP. This problem is addressed with the help of warm mix asphalt (WMA) which increases the proportion of RAP used by producing mixes having same/better properties viz., better workability, reduced viscosity than hot mix asphalt (HMA) at lower

PDF Laboratory Determination of Thermal Properties of Asphalt

thin-slab transient heat conduction procedure developed by the authors to determine the thermal conductivity (k) and diffusivity (a) of asphalt mixtures is described. By means of the heat conduction theory for plane walls, the time history of temperature at the midpoint of a thin slab is first derived. Next, this theoretical temperature-time history is matched with experimental measurements to arrive at a pair of k and a values that provide the best fit
