All Aggegate shall be of uniform quality, hard, durable,crushed stone or gravel, free from clay balls, vegetable matter, or other deleterious substances, meeting the requmments in the following
sections.
Paving Aggregate shall meet CDOT grading S, SE, or SX requirements for Superpave Hot Mix Asphalt (HMA) mix designs. Aggregates meeting the requirements in the properties table shall be used
to deviop the Job Mix formula for the HMA misturo. The eggegate should be composed of angular, coarse textured, tube shaped particles. - Natural fine material ( t" minus) shall be screerred out and
discarded before crushing. Sand may be used to obtain gradation of the blended aggegate mixture but should not exceed more than fifteen percent (15 %. If the percent of aggregate passing the #4
sieve is greater than ten percent (10 %) by weight of the indidual aggregate sample, plasticity will be determined in accordance with ASSHTO T 90. The gradation of the aggregates used in the mixture
shall meet the criteria shown in the Aggegale Master Range Table, and shall be will graded from course to fine. The nominal size aggegate used in the HMA mixture shall not be more than one-third ( §)
of the thickness of the HMA lift being constructed.
Base Course Gravel (Class 61 shall be t' minus crushed gravel or rock conforming to CDOT Class 6 gradation requirements, with an R value of seventy-eight (78) or greater. At least fdty percent (50
%) of the 114 plus fraction of the aggregate shell have at least two (2) fractured faces. Aggregate must meet a minimum hardness requirement defined by the L.A. Abrasion Test Material loss during
the lest shall not exceed forty-five percent (45 %) at five hundred (500) revolutions ( AASHTO T 96). COOT Class 6 base course gravel shall be compacted to ninety-five percent (95 %) "Modified
proctor' density, AASHTO T 180, between minus two percent ( -2 %) and plus three percent ( +3 %) of optimum moisture.
°i bas^, Gravel iC1ass2) shall be crused gravel or rock - conforming to CDOT Class 1 or Class 2 gradation requirements, with an R value of sixty­nine(69) or greater. Al least fifty percent (50 %) of the
#4 plus fraction of the aggregate shall have at least one (1) fractured face. Aggregate must meet a minimum hardness requrrement defined by the L.A. Abrasion Test: Material loss during the test shall
not exceed forty -five (45 %) at five- hundred (500) revolutions ( AASHTO T 96). Subbase gravel shall be compacted to ninety-three percent (93) "modified proctor' density. AASHTHO 180, between
minuslwnyeroent (2 %)and -plus three perecent( +3 %) of optimum moisture.
Class 3 (Pit Run, river Run, Hank Run) Gravel may be substituted for crushed Class 2 gravel when recommended by the Geotechnical Engineer based upon laboratory testing on the proposed
source. Thicker structural sections will be required when pit run is substituted for crushed Class 2 base course gravel. Pit run sources are subject to the approval of the Engineer. CDOT Class 3 pit run
gravel whall be compacted to mrity4hree percent (93 %) "modified proctor' derrsity, AASTTO T 180, between minus Iwo percent ( -2 %) and plus three percent ( +3 %) of optimum moisture.,
