TREATMENT OF PUMPING PAVEMENTS WITH CEMENT-SLURRY MIXTURES
EXPERIMENTAL TREATMENTS FOR CORRECTION OF PUMPING PAVEMENTS ARE MADE, USING A MIXTURE OF PORTLAND CEMENT AND CALCIUM ALUMINATE CEMENT AS A FILLING MATERIAL. A MECHANICAL PAVEMENT JACK IS USED TO CORRECT FAULTED JOINTS. JOINT PERFORMANCE WAS MEASURED BY COMPARING FAULTING BEFORE AND AFTER TREATMENT. IT WAS CONCLUDED THAT THE USE OF CEMENT SLURRY OF THIS TYPE IS PRACTICAL AND THAT, BASED UPON PERFORMANCE DATA, JOINTS TREATED IN THIS MANNER ARE GIVING SATISFACTORY SERVICE. COSTS WERE CONSIDERED MODERATE AND THE USE OF COMPARATIVELY EXPENSIVE MATERIALS APPEARS TO BE JUSTIFIED. THE USE OF THE PAVEMENT IN RE-ALIGNING FAULTED SLABS, WHEN USED IN CONNECTION WITH THE SLURRY TREATMENT, ALSO IS CONSIDERED TO BE A PRACTICAL METHOD OF CORRECTING JOINTS WHICH HAVE BEEN DAMAGED BY PAVEMENT PUMPING. /AUTHOR/
