§ 11-160. Corrective actions.

The following provides for corrective actions to be taken and/or provisions for accepting a street or road into the County System when test results indicate non-specification materials or workmanship have been incorporated into the project. Any penalties which are assessed shall be paid to the Washington County Road Department Fund by the owner/developer before a street or road will be accepted by Washington County. The penalties paid into the Washington County Road Department Fund shall be used at the discretion of the County Judge to maintain and/or construct roads and streets in Washington County.

(1)

Density for embankment, subgrade, pipe backfill, and crushed stone base course: Recompact until the minimum density is obtained.

(2)

Depth of lime treated subgrade: The depth of the lime treated subbase shall be at least five and one-half (5½) inches. If the depth is less than five and one-half (5½) inches, additional lime shall be added to the section represented by the test and the section reprocessed.

(3)

Depth of crushed stone base course: The depth of the crushed stone base shall be within ½ inch of the required depth. If the deficient depth is greater than one-half inch of the required depth, the existing material represented by the test(s) will be ripped up, new added and recompacted to the proper density. The average of all depth measurements shall not be less than the required depth shown in Table 2, Appendix A, and any depth in excess of + ½ inch will not be used in computing the average depth. If not, the deficient depth will be added to the required depth of the surface course or concrete pavement.

(4)

Density for asphalt treated base or cement treated base: When any individual density is below ninety-five (95) percent, the section represented by this test will be removed and replaced. The average of all densities shall be ninety-eight (98) percent or greater. If the average density of the project is below ninety-eight (98) percent the following penalties shall be assessed:

97.5 percent to 97.9 percent— 3 percent of the cost of the in-place material.

97.0 percent to 97.4 percent— 5 percent of the cost of the in-place material.

96.0 percent to 96.9 percent—10 percent of the cost of the in-place material.

95.0 percent to 95.9 percent—25 percent of the cost of the in-place material.

Below 95 percent—Remove and replace.

(5)

Depth of asphalt treated base or cement treated base: The depth of the asphalt treated base or the cement treated base shall be within ½ inch of the required depth. The average of all depth measurements shall not be less than the depth shown in Table 2, Appendix A, and any depth in excess of + ½ inch will not be used in computing the average depth. If not, the deficient depth will be added to the required depth of the surface course or concrete pavement.

(6)

Density of ACHM binder and surface: No individual density shall be lower than ninety (90) percent of maximum theoretical density. Any section with a density below that value shall be removed and replaced. The average of all densities for the project shall be not less than ninety-two (92) percent of maximum theoretical density. If this average is less than ninety-two (92) percent, the following penalties shall be assessed:

91.5 percent to 91.9 percent— 3 percent of the cost of the in-place material.

91.0 percent to 91.4 percent— 5 percent of the cost of the in-place material.

90.5 percent to 90.9 percent—15 percent of the cost of the in-place material.

90.0 percent to 90.4 percent—30 percent of the cost of the in-place material.

Below 90.0 percent—Remove and replace.

(7)

Depth of ACHM binder: The depth of the binder shall be within 3/8 inch of the required depth. The average of all depth measurements shall not be less than the depth shown in Table 2, Appendix A, and any depth in excess of + 3/8 inch will not be used in computing the average depth. If not, the deficient depth will be added to the required depth of the surface course or concrete pavement.

(8)

Depth of ACHM surface: The depth of the asphalt hot mix surface course shall be within ¼ inch of the required depth plus any additional depth(s) required due to deficient depths in the base and binder courses. The average of all depth measurements shall not be less than the required depth, and any depth in excess of + ¼ inch will not be used in computing the average depth. If the average depth is less, it will be corrected by overlaying with additional ACHM surface, or as directed by the County Road Superintendent.

(9)

Surface tolerance of ACHM surface: If the surface deviation is greater than + or - ¼ inch when checked with a ten-foot straight edge, the surface smoothness will be corrected as directed by the County Road Superintendent.

(10)

Class A structural concrete strength: The average twenty-eight-day compressive strength of the two (2) cylinders of a set shall be at least three thousand (3,000) psi. If the average strength is lower, the following penalties shall be assessed:

2,750 to 2,999 psi— 5 percent of the cost of the in-place material.

2,500 to 2,749 psi—10 percent of the cost of the in-place material.

2,250 to 2,499 psi—20 percent of the cost of the in-place material.

2,000 to 2,249 psi—40 percent of the cost of the in-place material.

Below 2,000 psi—Remove and replace.

(11)

Class S (AE) air entrained structural concrete strength: The average twenty-eight-day compressive strength of the two (2) cylinders of a set shall be at least four thousand (4,000) psi. If the average strength is lower, the following penalties shall be assessed:

3,750 to 3,999 psi— 5 percent of the cost of the in-place material.

3,500 to 3,749 psi—10 percent of the cost of the in-place material.

3,250 to 3,499 psi—20 percent of the cost of the in-place material.

3,000 to 3,249 psi—40 percent of the cost of the in-place material.

Below 3,000 psi—Remove and replace.

(12)

Concrete pavement strength: The average twenty-eight-day compressive strength of the two (2) cylinders of a set shall be at least four thousand (4,000) psi. If the average strength is lower, the following penalties shall be assessed:

3,750 to 3,999 psi— 3 percent of the cost of the in-place material.

3,500 to 3,749 psi— 7 percent of the cost of the in-place material.

3,250 to 3,499 psi—15 percent of the cost of the in-place material.

3,000 to 3,249 psi—25 percent of the cost of the in-place material.

2,500 to 2,999 psi—40 percent of the cost of the in-place material.

Below 2,500 psi—Remove and replace.

(13)

Concrete pavement depth: The concrete pavement depths shall be within ¼ inch of the required depth plus any additional depth required as a result of deficient subbase depth. The average of all depth measurements shall not be less than the required depth, and any depth in excess of + ¼ inch will not be used in computing the average depth. If the average depth is less, the following penalties shall be assessed:

Required depth to - 1/8 inch— 1 percent of the cost of the in-place material.

Minus 1/8 to -¼ inch— 3 percent of the cost of the in-place material.

Minus ¼ to - 3/8 inch— 7 percent of the cost of the in-place material.

Minus 3/8 to -½ inch —15 percent of the cost of the in-place material.

Minus ½ to - 5/8 inch —25 percent of the cost of the in-place material.

(14)

Any deviation greater than this shall be corrected by grinding, removing and replacing, or as directed by the County Road Superintendent.
