The results from this test method are used to calibrate aggregate spreaders and verify the uniformity of distribution transversely prior to construction of the surface treatment by determining the average quantity of aggregate spread per unit area.
The test method is useful for quality control during construction to monitor the spread rate.
The samples obtained during construction by this test method are useful for determination of moisture content and grading when such information is required.
1.1 This test method details the procedure for determining the aggregate spread rates in approximately 0.33-m (1-ft) transverse increments.
1.2 The values stated in SI units are to be regarded as standard. The inch-pound units shown in parentheses are for information only.
1.3 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.
