Significance and Use | ||||||||||||
5.1?Friction characteristics of traveled surfaces are monitored by skid measurement systems, and the operating procedure for the use of these systems is Test Method E274/E274M. However, dynamic measurement differences between these systems, that comply with the requirements of Test Method E274/E274M, require that each of these systems be correlated to each other system. The most effective approach to accomplish this correlation is to compare each system to a singular, highly accurate system, or to a very limited number (two or three) of systems, in a controlled environment. The ARSMSs were designed to be such systems. Fig. 1 depicts a skid measurement system and shows the general location of the major components. FIG. 1?Skid Measurement System 5.2?This guide defines the process of ensuring that the ARSMSs continue to accomplish their intended purpose. |

1. Scope | ||||||||||||
1.1?This guide covers validating area reference skid measurement systems (ARSMS) and related equipment. These systems have been used since 1976 to evaluate and correlate Test Method E274/E274M skid measurement systems used primarily as a pavement management tool by state Departments of Transportation. Also, this guide provides guidelines for the revalidation process following the replacement of components within an ARSMS. 1.2?This guide is offered as a process to identify and quantify the variables that affect system performance, to minimize the effect of these variables, and to provide a method of validating a new ARSMS to replace an existing ARSMS that has provided quality correlation data for a very long time. 1.3?The values stated in inch-pound units are to be regarded as the standard since the ARSMS will be compared with state departments of transportation systems that all currently use inch-pound units. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
