... Examples include environmental conditions, emulsion composition and dose, presence of active filler, moisture and density of the compacted material, and the milled surface of the existing pavement. The test methods described in this guide specification assess the raveling potential, penetration resistance, shear resistance, and stiffness of a newly constructed cold recycled pavement and could be used to supplement current agency testing practices for inspection and testing for acceptance of cold recycled materials (for example, in-place density, moisture content)

... 6.4 Test Frequency and Location 6.4.1 The raveling resistance test frequency can be similar to that of mat density measurement for recycled asphalt concrete layers set by the agency. Lot and sublot sizes should be established by the agency and used consistently for each of the test methods referenced in this guide specification.

... Lot and sublot sizes should be established by the agency and used consistently for each of the test methods referenced in this guide specification. The lot and sublot definitions should be established to appropriately balance agency and contractor risk.
