QUICK OBSERVATION OF THE BEARING CAPACITY OF PAVEMENTS BY CURVATURE MEASUREMENTS /IN PORTUGUESE/

A METHOD IS BEING DEVELOPED FOR THE QUICK APPRAISAL OF THE BEARING CAPACITY OF PAVEMENT/FOUNDATION SYSTEMS. THE AIM IS TO REDUCE THE NUMBER OF TIRE TESTS NEEDED. BY USING THE DEFLECTOGRAPH DEVELOPED AT THE LNEC FOR PAVEMENT STRENGTHENNG STUDIES. THIS METHOD, WHICH CONSISTS IN MEASURING THE CURVATURE OF THE PAVEMENT SURFACE UNDER A TIRE LOAD, IS SIMPLE, QUICK AND ECONOMICAL. ALTHOUGH INSUFFICIENT BY ITSELF AS A BASIS FOR STRENGTHENING STUDIES, THIS QUICK OBSERVATION METHOD WILL FACILITATE THE CLASSIFICATION OF ROAD SECTIONS ACCORDING TO THEIR PERFORMANCE AND THE SELECTION OF PLACES WHERE OBSERVATIONS SHOULD BE CARRIED OUT WITH A DEFLECTOGRAPH WITH A VIEW TO STRENGTHENING. THE CURVATURE METER THAT WAS CONSTRUCTED IS DESCRIBED AS WELL AS THE RESULTS ACHIEVED AND THE STUDY APPROACHES. /TRRL/
