§ 11-151. Testing.

(a)

The Developer shall, with the approval of the County Road Superintendent, retain the services of a testing laboratory or registered professional engineer, practicing in the materials and testing field, hereafter referred to as the lab engineer, to perform all sampling and testing. The Developer will be responsible for the costs of all sampling and testing performed on the project, including any additional sampling and testing as a result of failing tests and/or poor workmanship.

(b)

The lab engineer will report all test results to the County Road Superintendent.

(c)

In the case of failing tests or poor workmanship, the County Road Superintendent may direct the lab engineer to perform additional sampling and testing. The Developer will be responsible for the costs of any additional sampling and testing resulting from failing tests and/or poor workmanship.

(d)

The following is the minimum sampling and testing frequency:

(1)

Cross drain backfill: Minimum of one (1) density test per pipe or box culvert location.

(2)

Storm drain backfill: Minimum of one (1) density test per five hundred (500) lineal feet of pipe when the storm drain is located in the street or under the curb and gutter.

(3)

Embankment: Minimum of one (1) density test per layer per five hundred (500) lineal feet or roadway.

(4)

Subgrade: Minimum of one (1) density test, one (1) LL and one (1) PI per five hundred (500) lineal feet of roadway with a minimum of three (3) density tests and three (3) depth measurements per project. Also, there will be a minimum of one (1) gradation test and one (1) PI test per project.

(5)

Lime treated subgrade: Minimum of one (1) density test, one (1) depth measurement, one (1) LL and one (1) PI per five hundred (500) lineal feet of roadway with a minimum of three (3) density and three (3) depth measurements per project.

(6)

Base course: Minimum of one (1) density test and one (1) depth measurement (depth sounding) per five hundred (500) lineal feet of roadway, with a minimum of three (3) density tests and three (3) depth measurements per project. Also, there will be a minimum of one (1) gradation test and one (1) PI test per project.

(7)

Asphalt stabilized base (black base), ACHM binder, and ACHM surface courses: For each material, a minimum of one (1) density test and one (1) depth measurement per five hundred (500) lineal feet of roadway, with a minimum of three (3) density tests and three (3) depth measurements per project. Also, there will be a minimum of one (1) extraction to determine the asphalt content and aggregate gradation for each material for the project.

(8)

Structural concrete for drainage structures: A minimum of one (1) set of three (3) concrete cylinders per fifty (50) cubic yards of concrete or portion thereof. One (1) cylinder will be broken at seven (7) days and the other two (2) will be broken at twenty-eight (28) days.

(9)

Structural concrete for curb and gutter: A minimum of one (1) set of three (3) concrete cylinders per one thousand (1,000) lineal feet of curb and gutter. One (1) cylinder will be broken at seven (7) days and the other two (2) will be broken at twenty-eight (28) days.

(10)

Concrete pavement: A minimum of one (1) set of three (3) concrete cylinders per five hundred (500) lineal feet of pavement, with a minimum of one (1) set per project. The set shall be broken in seven (7) and twenty-eight (28) days as described above. Also, one (1) core and depth measurement per five hundred (500) feet of completed pavement with a minimum of one (1) per project.
