Abstract
A rut testing apparatus for testing the susceptibility of a pavement specimen to rutting has a specimen holder for supporting the specimen to be tested, a wheel, and a sensor. The specimen holder is arranged to support the specimen from below and to support two opposite ends of the specimen. The specimen holder is arranged to allow the specimen to deform in a lateral direction LD that is transverse to a direction that extends between the opposite ends. The wheel is arranged to move along at least part of the specimen in the direction that extends between the opposite ends. The sensor determines deformation of the specimen in the lateral direction LD.

A rut testing apparatus for testing the susceptibility of a pavement specimen to rutting, the apparatus comprising:
- a specimen holder for supporting the specimen to be tested, the specimen holder arranged to support the specimen from below and to support two opposite ends of the specimen, the specimen holder arranged so that one or more lateral sides of the specimen are substantially unsupported or supported by a moveable support member to allow the specimen to deform in a lateral direction that is transverse to a direction that extends between the opposite ends for substantially an entire test;
- a wheel that is arranged to move along at least part of the specimen in the direction that extends between the opposite ends;
- and
- a sensor to determine deformation of the specimen in the lateral direction.
A method of testing the susceptibility of a pavement specimen to rutting, the method comprising:
- supporting a pavement specimen in a specimen holder, the specimen holder arranged to support the specimen from below and to support two opposite ends of the specimen, the specimen holder arranged so that one or more lateral sides of the specimen are substantially unsupported or supported by a moveable support member to allow the specimen to deform in a lateral direction that is transverse to a direction that extends between the opposite ends for substantially an entire test;
- moving a wheel along at least part of the specimen in the direction that extends between the opposite ends;
- and
- measuring deformation of the specimen in the lateral direction.
