6.5.2 TEST STRIP.<br />
With the coordination of the owner, the contractor shall arrange for a test strip to be constructed<br />
on or near the project site under as reasonable as possible the anticipated placement conditions<br />
of time of day, temperature, and humidity. The test strip shall be 300 to 500 feet (91.4 – 152.4<br />
m) in length and shall be constructed with the job mix proportions, materials, and equipment to<br />
be used on the project. Adjustments to the mix design shall be permitted provided they do not<br />
exceed the values stated in Table 6.4. The test strip shall be evaluated by the owner to<br />
determine if the mix design and placement techniques are acceptable once the mixture has set<br />
and cured. If modifications to the mix design in excess of the values noted in Table 6.4 are<br />
necessary, a new mix design shall be prepared and another test strip constructed. The cost of<br />
the materials and placement of the rejected test strip shall be borne by the contractor including<br />
any removal costs.<br />
6.5.3 PROJECT DOCUMENTATION.<br />
After the project is underway, the contractor shall, on a daily basis, furnish the owner project<br />
documentation that includes the total amount of material delivered to the project and the total<br />
amount placed through the mixing machine from the dial gauges. The owner’s agent shall verify<br />
the dial gauge readings and material weights delivered and this information will be used to<br />
independently verify the mix proportions.<br />
6.6 CONSTRUCTION REQUIREMENTS<br />
6.6.1 WEATHER LIMITATIONS.<br />
Slurry systems shall not be applied if either the pavement temperature or the air temperature is<br />
below 50°F (10°C) and falling. No material shall be applied when there is the eminent possibility<br />
of rain or if the finished product is subject to freezing within 24 hours. The mixture shall not be<br />
applied when weather conditions prolong opening to traffic beyond a reasonable time.<br />
6.6.2 MIXING EQUIPMENT.<br />
The materials shall be mixed in a specifically designed piece of equipment, either truck mounted<br />
for small applications and residential work, or continuous run machine for larger projects such<br />
as highways and airports. The machine must be a continuous-flow mixing unit able to<br />
accurately proportion and deliver the aggregate, emulsified asphalt, mineral filler, additives, and<br />
