IMPROVEMENT OF THE BEHAVIOUR OF STABILIZED ROADBASES AT THE FOUNDATION/BASE INTERFACE

AMELIORATION DU COMPORTEMENT A L'INTERFACE FONDATION-BASE DES ASSISES TRAITEES

AN ATTEMPT WILL BE MADE TO FIND SOLUTIONS TO THE PROBLEM OF ADHESION BETWEEN THE SUBBASE AND THE ROADBASE OF STABILIZED PAVEMENTS BY MEANS OF LABORATORY SIMULATION STUDIES AND IN-SITU EXPERIMENTS. IN 1979 IT IS PLANNED: TO CONTINUE LABORATORY SIMULATION TESTS ON SAMPLES PREPARED WITH A PLATE COMPACTOR WITH DIFFERENT TYPES OF FOUNDATION/ ROADBASE INTERFACE; TO CONDUCT FULL-SCALE EXPERIMENTS WITH FOLLOW-UP STUDY OF BEHAVIOUR.
