Rock <br />346 embankment material shall be placed in layers in accordance with the requirements of subsection <br />347 203.06. <br />348 <br />349 Each layer of rock embankment material shall be compacted by routing construction equipment, <br />350 compactors, or both, uniformly over the entire surface of each layer before the next layer is <br />351 placed. At least one compactor shall be in simultaneous operation with each separate rock <br />352 embankment placement operation. Specific types of compactors shall be furnished and used <br />353 when required by the Contract. <br />354 <br />355 Each layer of rock embankment shall not be covered by another layer until the Engineer is <br />356 satisfied that adequate compaction has been obtained. If the Engineer determines that the <br />357 compactive effort is unsatisfactory, the Engineer may order the Contractor to compact the <br />358 unsatisfactory area by two additional passes using approved compaction equipment. <br />359 <br />360 203.09 Proof Rolling. Proof rolling with pneumatic fire equipment shall be performed using a <br />361 minimum axle load of 18 kips per axle. A weigh ticket from an approved scale shall be fumished <br />362 by the Contractor to substantiate this weight. <br />363 <br />364 The subgrade shall be proof rolled after the required compaction has been obtained and the <br />365 subgrade has been shaped to the required cross section. <br />366 <br />367 The proof roller shall be operated in a systematic manner so that a record may be readily kept of <br />368 the area tested and the working time required for the testing. Areas that aze observed to have soft <br />369 spots in the subgrade, where deflection is not uniform or is excessive as determined by the <br />370 Engineer, shall be ripped, scazified, dried or wetted as necessary and recompacted to the <br />371 requirements for density and moisture at the Contractor's expense. After recompaction, these <br />372 azeas shall be proof rolled again and all failures again corrected at the Contractor's expense. <br />373 <br />374 Upon approval of the proof rolling, the sub base, base course, or initial pavement course shall be <br />375 placed within 48 hours. If the Contractor fails to place the sub base, base course, or initial <br />376 pavement course within 48 hours or the condition of the subgrade changes due to weather or <br />377 other conditions, proof rolling and correction shall be performed again at the Contractor's <br />378 expense. <br />379 <br />3-9 <br />G:1101\00100.02\Hlgeports\KP1TeNniral Sperifralions.EOC February 3,1006 <br />
