EVALUATION OF STONE/RAP INTERLAYERS UNDER ACCELERATED LOADING - CONSTRUCTION REPORT

Three test lanes were constructed at the Louisiana Pavement Research Facility to study the performance of Reclaimed Asphalt Pavement (RAP) as a stress relieving layer between the cement treated base and asphalt concrete layers in lieu of crushed stone. The first test lane consisted of a RAP base over 10 in. of cement treated subgrade with 5% cement. The second test lane consisted of a RAP base over 6 in. of soil cement treated subgrade with 10% cement. The third test lane (control section) consisted of a stone base over 6 in. of soil cement treated subgrade with 10% cement. A 4-in. perforated drain pipe system was also constructed in the embankment. This interim report documents the construction of the three test lanes, including the drainage system. Properties of the drainage system, base materials, and hot mix asphalt used for this construction are included along with a detailed instrumentation plan. All sections were constructed utilizing current Louisiana Department of Transportation and Development standard specifications and special provisions.
