Florida Administrative Code › 14 - DEPARTMENT OF TRANSPORTATION › 14 - Departmental › Chapter 14-103 - CONSTRUCTION AGGREGATES › Section 14-103.005 - Supplemental Source Requirements for Alternate Open-Graded Friction Course (FC) Aggregate

Current through Reg. 50, No. 138; July 16, 2024
Approval may be sought for coarse aggregate not specifically
				  mentioned by name in the Department's
Standard Specifications for Road
				  and Bridge Construction
use in open-graded Friction Course Asphalt
				  Mix, Type 5 (FC-5). The following approval requirements are in addition to the
				  requirements of Rule 14-103.004, F.A.C., for such
				  alternate materials having characteristics which will result in a friction
				  course providing acceptable long-term frictional characteristics. Once
				  approved, coarse aggregate may be submitted in all Department friction course
				  mixes subject to specification requirements.
(1) A detailed description of the location
				within the overall mining site of the specific deposit proposed for use in an
				FC-5, and a description of the unique characteristics of this deposit which can
				be used to differentiate it from other material occurring at the site. These
				characteristics will include such things as color, texture, hardness, physical
				or chemical properties, and other properties determined in accordance with the
Sampling and Testing Methods
or in accordance with paragraph
				14-103.006(14)(c),
				F.A.C.
(2) An estimate of the
				quantity of material available.
(3)
				A determination of the acid insoluble material retained on the No. 200 mesh
				sieve (FM 5-510) must be submitted on at least five samples.
(4) Submission of any test data which the
				producer considers significant to potential friction characteristics, such as
				wear tests, hardness, crushed faces, angularity, and other relevant
				characteristics.
(5) The
				construction of a trial section of FC-5 pavement from the material will be
				required by the State Materials Office based on history of use and performance.
				The construction of the FC-5 trial section will be the sole responsibility of
				the producer. The State Materials Office will design the mix, monitor
				construction, obtain samples for evaluation, and test the friction
				characteristics of the surface. The trial section will be a minimum of 500 feet
				in length to accommodate friction testing, and shall be constructed on a
				roadway not maintained by the Department. No minimum traffic volume will be
				required for approval of trial sections.
(6) The information supplied by the producer,
				the inspection of the mine, and any test results from a trial section will be
				reviewed by the State Materials Office. If the material indicates a potential
				for use in an FC-5, the producer will be notified and a test section will then
				be selected by the producer for Department evaluation of the wear
				characteristics of the material. The State Materials Office will assist the
				producer in the selection of a test section which meets the following criteria:
(a) Minimum 50 miles per hour speed
				limit.
(b) Minimum 14,000 Average
				Daily Traffic.
(c) No intersection,
				ramps, driveways or curves.
(d)
				Minimum of four lanes.
(e) Minimum
				length of 1,000 feet.
A control section meeting the test section criteria and
				  adjoining the test section will be constructed with a Department approved
				  aggregate.
