The screen aperture be selected so that only the minimum quantity of Screen Aperture material is removed from the existing stockpile to satisfy this requirement. Basecourse material having any dimension greater than 50mm shall be deemed oversize and shall not be delivered to the pavement construction area. (NOTE: need for alternative paragraphs 1 to 4, and then delete this note refer Guidance Note 3) – The Particle Size Distribution shall be determined in accordance with Test Particle Size Method WA 115.1. The particle size distribution of the portion passing a Distribution 37.5mm AS sieve shall conform to the grading limits shown in Table 501.07. The grading of material passing the 37.5mm sieve shall vary from coarse to fine in a uniform and consistent manner. The material shall not be gap graded as represented by the grading crossing from the maximum limit for one sieve size to the minimum limit for another sieve size, and shall conform as closely as possible to the specified target grading. The material shall also comply with the limits shown in Table 501.08. The Other Acceptance Secondary Mineral Content in Basic Igneous Rock test is only applicable to Limits basic igneous rock. The Accelerated Soundness Index test is only applicable to basic igneous rock.
