Significance and Use | ||||||||||||||
The procedure in this practice for estimating the percentage of coated particles after varying mixing times is used to establish the least mixing time required to produce satisfactory coating for a given set of conditions. This procedure can also be used to sample cold mixtures from stockpiles to determine that satisfactory coating has been retained in the stockpile. This procedure is used with hot-mixed, hot-laid bituminous paving mixtures such as specified in Specification D 3515 or with cold-mixed, cold-laid bituminous paving mixtures such as specified in Specification D 4215. Note 1—Even when a paving mixture complies with the “percent of coated particles” that may be specified, there is no assurance that the asphalt cement is uniformly distributed throughout the mixture. |

1. Scope | ||||||||||||||
1.1 This practice provides an estimate of the degree of particle coating in a bituminous-aggregate mixture on the basis of the percentage of coarse particles classified as being completely coated. 1.2 The values stated in SI units are regarded as being standard. 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. |
