Abstract
A method of testing pavement includes repeatedly simulating wheel loading on the pavement by repeatedly applying a plurality of discrete forces with a downwards component, in series and one after the other, to an upper surface of a test strip of the pavement thereby to simulate a load exerted by a travelling wheel and hence subjecting the pavement to accelerated testing. The discrete forces are provided by repeatedly actuating a series of actuators, one after the other, each to exert a force with a downwards component to the upper surface of the test strip of pavement, or to a portion thereof.
