Historical Standard: Standard Practice for Calibration of Systems Used for Measuring Vehicular Response to Pavement Roughness<\/h4>\n
\n

ASTM E1448<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This practice describes equipment and procedures for the calibration of systems used for measuring vehicular response to pavement roughness. Such systems are referred to as response-type systems. (See Test Method E 1082.)<\/p>\n

1.2 The response-type system includes the driven vehicle, the driver and contents of the vehicle, the towed trailer (if one is used with the system), and a device called a road meter that measures the vehicle response to pavement roughness. The road meter may be mounted in an automobile, van, or in a towed trailer. Response-type (road meter) devices covered in this practice include: devices measuring the relative axle-body motion of a vehicle, devices measuring the vertical acceleration of the vehicle body, and devices measuring the vertical acceleration of the vehicle axle.<\/p>\n

1.3 The calibration procedures described in this practice are limited to the use of the simulations described in Practice E 1170.<\/p>\n

1.4 This practice is not intended to apply to pavement roughness measuring equipment whose output is not influenced by the response of the host vehicle.<\/p>\n

1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses may be approximate and are for informational purposes only.<\/p>\n

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/p>\n
