SECTION 401
3.17.2.3 Sublot Size. The quantity represented by each sample will constitute a sublot. The size of each sublot shall be as
listed under the sublot size heading in Table 401-4. If there is insufficient quantity in a lot to make up at least three sublots of
the designated size in Table 401-4, then the lot quantity will be divided into three equal sublots.
If there is less than one half of a sublot remaining at the end, then it shall be combined with the previous sublot. If there is
more than one half sublot remaining at the end, then it shall constitute the last sublot and shall be represented by test results.
3.17.2.4 Test Results. The Engineer may calculate pay factors and pay adjustments at any time while a lot is being
produced. This may be necessary for a partial estimate or to see if quality is falling to a point where immediate attention is
required. Pay factors will be determined from all available acceptance tests for the lot being evaluated.
3.17.3 Acceptance Testing
3.17.3.1 Gradation and Asphalt Binder Content. Samples for gradation and asphalt binder content shall be obtained from
behind the paver in conformance with NHDOT procedure B-7 (sce appendix A) and taken from each pavement layer by the
Contractor in the presence of the Engineer. The sample locations will be established by selecting a random location within each
sublot in accordance with Section 106. Sample locations (center of sample) will not be within 1 foot from an edge of pavement
or within 4 feet from any structure. Sample locations falling within 4 feet from any structure will be relocated 4 feet from the
structure along station at the same offset.
Where samples have been taken, new material shall be placed and compacted to conform to the surrounding area immediately
afier the samples are taken. Samples shall be accompanied by a sample tag containing the following information:
a) Project name and number.
b) Lot and sublot number.
c) Material type.
d) Date placed.
e) Location in station and offset, tonnage
f) Contract Administrator
g) Sampler
h) Item number
When the project exceeds 30 minutes travel time from the testing laboratory location, material samples will be taken and
identified by NHDOT project personnel and shall be transported before cooling by the Contractor and delivered to NHDOT
testing technicians at the testing laboratory location. Samples lost in transit will incur a penalty of 5% of the bid price for the
entire sublot represented by that sample. Sublots with no test results due to a lost sample will not be evaluated and the total
quantity represented by that sublot shall not be included in any positive pay factor.
3.17.3.1.1 Testing. Target values shall be as specified in the job mix formula. All sieve sizes specified in the job mix
formula will be evaluated for gradation. The specification limits in Table 401-5 will be used for calculating pay factors for
gradation and asphalt binder content.
