Equipment used to place and compact the coarse gravel shall be not travel <br />directly on the underlying geomembrane. <br />3. The EARTHWORK CONTRACTOR shall use low ground pressure <br />equipment to place the coarse gravel. The following table shall be complied <br />with during construction: <br /> <br />Maximum <br />Equipment Ground Pressure <br />(psi) <br /> <br />Initial Lift Thickness <br />(ft) <br />< 5 0.5 <br />5 1.0 <br />10 1.5 <br />20 2.0 <br />>20 >3.0 <br /> <br /> 3.

If acceptance tests conducted by the QA/QC CONSULTANT <br />indicate that the Coarse Gravel does not meet specified requirements, the <br />EARTHWORK CONTRACTOR shall terminate material placement until <br />corrective measures are taken. <br /> 2. Coarse Gravel Acceptance: Final acceptance of the Coarse Gravel will be <br />based on all tests made on completed Work or on samples of material taken <br />from the completed layer. Testing for final acceptance shall be performed <br />by the QA/QC CONSULTANT in accordance with these Specifications and <br />the CQA Manual. <br /> <br /> D. Protection: <br /> <br /> 1. Do not route construction traffic on top of Coarse Gravel layer once <br />material has been placed. <br /> 2.
