Section 311. — STABILIZED AGGREGATE SURFACE

COURSE

11/12/20– FP-14

Delete the text of this Section and substitute the following:

Description

311.01 This work consists of constructing a stabilized aggregate layer with imported surface course aggregate. The aggregate layer is stabilized by incorporating a solid form of calcium chloride.

Material

311.02 Conform to the following Subsections:

Calcium chloride (flake/pellet) 725.02(b) Imported surface course aggregate 703.05A Water 725.01(c)

Construction Requirements

311.03 Proportioning.

(a) Imported Surface Course Aggregate. Determine the maximum density and optimum moisture content according to AASHTO T 180, method D for the imported surface course aggregate in two ways; first for the aggregate without calcium chloride, and second for the aggregate mixture including calcium chloride at the target percentage. Use the proctor with calcium chloride to monitor yield and final compaction of the mixture.

The target calcium chloride content is 1.85 percent by dry mass of aggregate. The target water content is from 2 percent below the optimum moisture content to optimum moisture content.

(b) Imported Surface Course Aggregate, In-Place Stabilization, H-01 Road. Determine the maximum density and optimum moisture content according to AASHTO T 180, method D for the imported surface course aggregate in two ways; first for the new imported aggregate without additional calcium chloride, and second for the ultimate combination of new and existing aggregate including calcium chloride at the target percentage. Use the proctor with calcium chloride to monitor yield and final compaction of the mixture.

The target calcium chloride content is 1.85 percent by dry mass of aggregate. The target water content is from 2 percent below the optimum moisture content to optimum moisture content.
