CONSTRUCTION <br /> A . Equipment - Use equipment that will produce the completed base course in -place as <br /> follows : <br /> 1 . Use a single processing unit capable of planing, sizing and mixing all materials <br /> in -place and which are capable of placing the recycled base course in a single <br /> pass lay down . The single unit train must recycle a minimum lane width of ten <br /> feet in one pass . <br /> 2 . Use a multi -unit train capable of planing, sizing and mixing all materials in- <br /> place as specified . Up- cutting machines shall not be permitted unless <br /> secondary crushing is conducted in-place prior to mixing and the introduction <br /> of bituminous material . The multi -unit train must recycle a minimum lane <br /> width of ten feet in one pass . <br /> 3 . Use only bituminous pavers as specified in FDOT Standard Specifications <br /> for Road and Bridge Construction 2000, Section 320- 6 for lay down of <br /> materials . <br /> 4 . Maintain all equipment in a satisfactory operating condition as specified in <br /> FDOT Standard Specifications for Road and Bridge Construction 2000, <br /> Section 320 . <br /> 5 , Recycling Around Utilities - So as to recycle 100 % of the roadway, use a small <br /> milling machine to mill to a minimum depth of 5 " longitudinally around all <br /> manholes , inlets and any other structures not accessible or practical to be <br /> milled by milling/mixing machine . The milled product produced by the small <br /> mill will be the same as the large mill and of equal gradation to produce a <br /> uniform recycled bituminous base course . Remove milled material and replace <br /> with new recycled bituminous base course material or binder. <br /> B . Mixing - Mixing of all reclaimed materials , aggregate and emulsified asphalt <br /> will be conducted in-place . Maintain a proper moisture content to assure <br /> thorough mixing of all materials in-place . <br /> 1 . In-Place Mixing - Spread the required quantity of reclaimed material and <br /> aggregate, if required, on the prepared area in a uniform loose layer to obtain <br /> the specified compacted depth. Adjust the travel speed of the mixer to obtain a <br /> thorough and uniform mixture in a single pass . <br /> 2 . Ensure that positive displacement pumps accurately meter the planned amount <br /> of bituminous material and the milling machine mixes it thoroughly with the <br /> RAP materials . The pump shall be mechanically or electronically interlocked <br /> with the ground speed of the machine . The bituminous metering system and <br /> water metering system shall be capable of continuous monitoring (GPM) flow, <br /> and totaling the quantity of bituminous material applied into the mixing <br /> chamber. <br /> FAPublic Works\Capital Projects\CR 512 & Oslo- Milling, Resurfacing and Shoulder Paving\Bid Document5 . 18 .04.doc <br /> Page 21 of 58 <br />
