1 Correlate results from the contractor’s and department’s density tests during placement

of test strip. Use the following procedures:

1.The engineer will mark seven randomly selected locations using a table of random

numbers with exclusion of locations within 12 in [300 mm] of the pavement edge.

2.Take one pair of core samples from each sample location, in the presence of the

engineer.

3.The department and the contractor will dry the cores to constant weight [mass]

using a nondestructive method.

4.Test one sample from each of the seven pairs of dry cores for bulk specific gravity

and density; do so independent of the department.

5.The engineer will test the other sample from each of the seven pairs of dry cores

independent of the contractor.

6.The engineer will perform the statistical evaluation after the seven pairs of tests

have been completed. 114.3.4 Resolving Field Testing Discrepancies 1 Resolve discrepancies as follows:

1.Meet with department personnel and review testing procedures, equipment

condition, and equipment calibrations in attempt to solve the problem.

2.When cause of the discrepancy has been identified and corrected, repeat the

correlation procedure.

3.If the second correlation determines that the contractor’s and department’s test

results represent different sample populations, conduct referee testing.

4.The Materials Program will conduct the referee tests using the retained referee

samples for aggregate gradations and the department’s cores for density testing.

5.The Materials Program will make its results available within five working days of

receiving the samples.

6.If the samples represent a quality acceptance lot, the engineer will use test results

correlating with the Materials Program test results for the quality acceptance calculations.

Clearing and Grubbing

201.1DESCRIPTION

1 This section describes the requirements for clearing, grubbing, removing, and disposing

of vegetation and debris.

201.2MATERIALS—Vacant

201.3EQUIPMENT—Vacant

201.4CONSTRUCTION

201.4.1 General 1 The engineer will establish right-of-way and construction lines and designate vegetation

and other objects to remain. Protect from harm or defacement any vegetation and objects designated to remain. 201.4.2 Clearing and Grubbing 1 Clear or grub surface objects, trees, shrubs, plants, stumps, roots, and other protruding

obstructions not specified to remain. 2 Fell and remove timber in a way that minimizes damage to riparian habitat. 3 Except in urban areas, stumps outside slope stake limits may remain in place if cut flush

with the ground. In urban areas, cut stumps flush and grind to below grade. 4 Backfill with suitable material and compact holes left by removed stumps and other

obstructions, in accordance with Subsection 203.4.3, Embankment and Cut Areas with Moisture and Density Control. 5 Unburned refuse and debris become the property of the contractor; remove it from the

right-of-way. 201.4.3 Mulching 1 Incorporate brush and existing vegetation that can be used as mulch into the topsoil in

accordance with Subsection 207.4.1, Topsoil, Construction, General.
