TECHNICAL REPORT STANDARD PAGE

OGFC (open graded friction course) is a porous, gap graded asphaltic concrete mixture that contains a high percentage of interconnected air voids These types of mixtures are also referred to as Permeable Friction Course (PFC) and primarily designed as a thin wearing.

Four ways open graded friction courses can reduceProper design, selection and construction of open graded friction course (OGFC) pavements will and have reduced hydroplaning OGFC is an asphalt mixture comprised of a high percentage of coarse aggregates that are almost uniform in size, higher than normal amounts of performance graded asphalts that are normally polymer modified, and a small.Improving Durability of Open Graded Friction Coursesmum binder content was determined by using the open graded friction course mix design procedure described by FHWA Results of this study indicate that optimum asphalt content of open graded friction course mixtures varies depending on the asphalt, anti­ stripping agent type, and.Hot Mix Asphalts 101• Dense Graded (DGA) Size evenly distributed from smallest to largest size (well graded) • Open Graded (or Uniformly Graded) Friction Course (OGFC) Primarily coarse aggregate with few fines • Stone Mastic (Matrix) Asphalt (SMA) Mid size aggregate missing or reduced Stone Matrix Asphalt Open Graded Friction Course Dense Mix.AsphaltOpen Graded Asphalt Concrete Friction Course Design Method 8/23/1999 ALDOT 307 Design Method for Selecting Optimum Asphalt Cement Content of Bituminous Mixture by Means of the Marshall Apparatus 10/20/2008 ALDOT 319 Rapid Method to Determine the Bitumen Content in Bituminous Paving Mixtures.Micromechanical investigation of open graded asphaltThree open graded asphalt mixture types were used in this study as surface friction courses, a polymer modified (PM) mixture with PG76 22PM binder and 475 mm nominal maximum aggregate size (NMAS), a PM mixture with PG76 22PM binder and 95 mm NMAS and a conventional mixture with PG64 10 binder and 475 mm NMAS.Guidelines on Construction and Maintenance of PorousPorous Friction Courses, Open Graded Friction Courses, Porous Asphalt, Mixture Design, Asphalt Mixture, Asphalt, Permeability, Noise reduction, Maintenance, Construction, Aging, Clogging 18 Distribution Statement No Restrictions This document is available to the public through NTIS National Technical Information Service.400 Flexible Pavement Design Table of Contents 400example, Item 441 Asphalt Concrete Surface Course, Type 1, PG64 22 is the exact same material whether the acceptance is 446 or 448 The acceptance method for most surface and intermediate courses.State of the Practice in 2006 for Open Graded Asphalt MixState of the Practice in 2006 for Open Graded Asphalt Mix Design Author A Ongel, JHarvey, and E Kohler , MOGFC Modified asphalt binder open graded friction course , NMAS Nominal maximum aggregate size OGAC Open graded asphalt concrete OGFC Open graded friction course PA Porous asphalt PCC Portland cement concrete.Welcome to ROSA POpen Graded Friction Course (OGFC) has been used since 1950 in the United States to improve the frictional resistance of asphalt pavements However, experience of states with this kind of mix has been widely varied While many transportation agencies have reported good performance, many others have stopped using OGFC due to poor performance.Sixth Edition 2019or base course) Other Pavement types include OPEN GRADED FRICTION COURSE MODIFIED OPEN GRADED FRICTION COURSE ASPHALT RUBBER OPEN GRADED FRICTION COURSE ULTRA THIN FRICTION COURSE SMA (S tone Matrix Asphalt) ESTIMATING QUANTITIES For a cursory estimate of the quantity of material required, use—1 ton of hot mix asphalt covers 17.ASPHALT RUBBERThis paper will discuss the use of asphalt rubber materials as the binder for open graded friction course applications Proper binder design, mix design and construction procedures will be discussed and applied to the benefits concerning the use of asphalt rubber open graded friction course (AR OGFC).
