STABILIZED SUBGRADE

PART 1 GENERAL

1.1 SCOPE

A. Where it fails to meet the specified Limerock Bearing Ratio (LBR) 40, stabilize the subgrade to the uniformity, density and bearing ratio specified hereinafter. Stabilize parking areas to a minimum depth of 12 inches below the bottom grade of the base material and to a width 6 inches outside each pavement or concrete curb edge. Stabilize roadways and streets to 12 inches unless otherwise indicated on the Drawings.

B. Definitions: Use FDOT Type B stabilization as described hereinafter to obtain the required bearing ratio by the addition and mixing in of suitable stabilizing material.

PART 2 MATERIAL

2.1 GENERAL

A. Use either Commercial Materials or Local Materials as defined hereunder, at the Contractor's option.

B. Commercial Materials: Limerock, limerock overburden or crushed shell meeting the following requirements:

• At least 97 percent by weight of the total material passing a 1 inch screen and at least 50 percent by weight of the total material retained on the No. 4 sieve.

• Not more than 7.5 percent by weight of the total material passing the No. 200 sieve as determined by washing the material over the sieve

• In the event that the shell meets the above requirements without crushing, crushing will not be required. The use of steamed shell will not be permitted.

C. STABILIZATION

• Determine bearing value by the Limerock Bearing Ratio (LBR) Method.

• After grading operations are substantially complete, determine the quantity (if any) of selected stabilizing material to be added for compliance with the bearing value requirements.

• Ensure that the finished subgrade meets the bearing value requirements, regardless of the quantity of stabilizing materials necessary to be added.

STABILIZED SUBGRADE 01240 - 2

PART 3 EXECUTION

3.1 PREPARATION

A. GENERAL

• Prior to the beginning of stabilizing operations, complete the subgrade to the lines, grades and cross section shown in the plans.

• Stabilize the subgrade in one course, unless the equipment and methods being used do not provide the required uniformity, particle size limitation, compaction and other desired results, in which case, perform the processing in more than one course as approved by the Engineer.

3.2 APPLICATION

A. Stabilizing Material: Spread the stabilizing material uniformly over the area to be stabilized by means of mechanical material spreaders, except that where use of such equipment is not practicable other means of spreading may be used, but only upon written approval of the Engineer.

B. Mixing: By means of rotary tillers, or other equipment meeting the approval of the Engineer, thoroughly mix the subgrade throughout the entire depth and width of the area to be stabilized.

C. Maximum Particle Size Of Mixed Materials: At the completion of mixing, check that all particles of material within the limits of the area to be stabilized pass a 3 ½-inch ring.

Remove from the stabilized area any particles not meeting this requirement or break them down so as to meet this requirement.

D. Compaction: After the mixing operations have been completed and requirements for bearing value, uniformity and particle size have been satisfied, compact the stabilized area to a density of not less than 98% of maximum density as determined by AASHTO T 180. Compact the materials at a moisture content permitting the specified compaction. If the moisture content of the material is improper for attaining the specified density, either add water or allow drying until the proper moisture content for the specified compaction is reached.

E. Finish Grading: Grade and shape the completed stabilized subgrade to conform with the finished lines, grades and cross-section indicated in the Drawings.

F. Quality Assurance:

• After the stabilizing and compacting operations have been completed, check that the subgrade is firm and substantially unyielding, to the extent that it will support construction equipment and will have the bearing value required.

STABILIZED SUBGRADE 01240 - 3

• Remove and replace with suitable material all soft and yielding material, and any other portions of the sub-grade which will not compact readily, and bring the whole subgrade to line and grade, with proper allowance for subsequent compaction.

G. Maintenance Of Completed Subgrade: Upon completion, maintain the subgrade free from ruts, depressions and any damage resulting from the hauling or handling of materials, equipment, tools, etc. Maintain the required density until the subsequent base or pavement is in place. Make any repairs, replacement, etc., of curb and gutter, sidewalk, etc., which might become necessary in order to recompact the subgrade in the event of underwash or other damage. Construct and maintain ditches and drains as necessary to protect the completed subgrade from damage by storm water.

3.3 FIELD QUALITY CONTROL
