BEARING CAPACITY ACROSS THE TRANSVERSE PROFILE OF OLD GRAVEL ROADS

BAERIGHETSPROFIL TVAERS VAEGKROPPEN HOS GAMMAL GRUSVAEG

A measure of the bearing capacity of a road is the deflection obtained under a standardized load, for instance that of a falling weight deflectometer. The load pulse from such an apparatus simulates the load under a moving truck wheel. The deflection caused by load pulse is recorded by means of a special device designed for the purpose. In the present work, the measurements of the bearing capacity were made at points aligned across the road in order to facilitate the recording of the bearing capacity across the transverse profile. The results show that the deflection varies across the road and according to the categories of road materials. The deflection also has a different variation pattern along the edges. The low bearing capacity part of the cross section is about 10% of the width of the road. The deflection within 90% of the road width is moderate and shows moderate variation in the roads studied. The work also deals with the most advantageous location of the measurement points along the road and analyses particular strengthening jobs. (Author/TRRL)
