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.
Claims11
An accelerated pavement testing device which comprises
- a carrier;
- and
- an array of at least five actuators carried by the carrier, wherein each actuator is configured to repeatedly apply a discrete force with a downwards component to an upper surface of a test strip of pavement, each actuator being associated with at least one force transfer element or sole configured in use to transfer said discrete force from the actuator to pavement being tested, and the actuators in the array being configured repeatedly to be actuated one actuator after the other actuator in series thereby to simulate a load exerted by a travelling wheel to said test strip of pavement and hence over time to subject the pavement to accelerated testing.
