A Porous Asphalt BMP is a BMP where the surface is composed of an asphalt open-graded friction course (OGFC) manufactured with larger-diameter aggregates to achieve an effective porosity of
TRB's National Cooperative Highway Research Program (NCHRP) Research Report 877: Performance-Based Mix Design for Porous Friction Courses presents a proposed mix design method for porous asphalt friction course (PFCs).
In Europe, these materials are known as "porous asphalt mixes" and they are used for the same reasons as in the U.S., as well as to lessen tire/pavement noise. In general, European porous mixes have higher air-void contents than those in the U.S., ranging between 20 and 25 percent;
– Potentially high air voids in 12H76 mix placed on bridge deck • No vibration on during rolling • Coarse, stiff mix with most likely low asphalt ... • Must supply for mix design verification and control (1st Lot and every other Lot after) Typical Permeability Values ... • 2 projects using it as surface course – Evaluating general ...
Cost, Intersection Design, and Porous Pavements for Commercial Facilities. The manual contains the necessary information to allow the user to do the following: 1) Select and specify the correct asphalt concrete mix for a given application.
Comparison of Mix Design Methods for Porous Asphalt Mixtures Bradley J. Putman, A.M.ASCE1; and Laura C. Kline2 Abstract: Porous asphalt mixtures have been used for more than 60 years, but it was not until 1974 that the first formalized procedure was

INTRODUCTION. ... ponds, infiltration basin, porous concrete, porous asphalt, swales, and filter strips. Depending on the hydraulic
Porous asphalt is an environmentally friendly tool for stormwater management. In the natural environment, rainfall sinks into soil, filters through it, and eventually finds its way to streams, ponds, lakes, and underground aquifers.
Both the history of the technology and the latest large-scale projects, including innovative uses of porous pavements, are discussed. Topics covered include water quality, structural design, soil investigation, hydrologic design, materials, construction, cost, …
Talley Construction uses a warm mix design that eliminates fibers from the porous asphalt on a parking lot project in Tennessee. December 7, 2011 The asphalt was applied in two 4-inch lifts of AS ...
NJDOT Design Manual – Roadway 8-23 ... Non-vegetative Surface, Porous Hot Mix Asphalt: NJDEP considers Porous HMA as impervious cover for stormwater management (Flood Hazard Control Act). The Delaware and Raritan Canal Commission considers Porous
The objectives of study were to obtain a porous asphalt mix design procedure for the achieved gradation recommended by National Centre for Asphalt Technology (NCAT) using the locally available aggregates, to determine the …
temperatures of asphalt mix rely on the viscosity of the asphalt binder used. Laboratory Simulation of Porous Asphalt Parking Lot System and Mix Design 221 Journal of Engineering Science and Technology April 2013, Vol. 8(2)
Porous asphalt is produced and placed using the same methods as conventional asphalt concrete; it differs in that fine (small) aggregates are omitted from the asphalt mixture. The remaining large, single-sized aggregate particles leave open voids that give the material its porosity and permeability.

With the proper design and installation, porous asphalt can provide cost-effective, attractive pavements with a life span of more than twenty years, and at the same time provide storm-water management systems that promote infiltration, improve water quality, and many times eliminate the need for a detention basin.
Porous asphalt pavements allow for land development plans that are more ... porous asphalt pavement design are: n Consider the location for porous pavements early in the site ... cover on the porous asphalt was the same as on conventional dense-mix asphalt. CONSTRUCTION GUIDELINES The following are some general

Materials and Mix Design . Pervious concrete uses the same materials as conventional concrete, with the exceptions that the fine aggregate typically is eliminated entirely, and the size distribution (grading) of the coarse aggregate is kept narrow, allowing for relatively little particle packing.
permeable, or open-graded asphalt, porous asphalt is a type of hot-mix asphalt, with less sand or fines then a dense graded mix. The reduced fines leave stable air pockets in the asphalt, ... 2 Porous Asphalt Pavement Design 2.1 Site Selection Porous pavements have traditionally been limited to parking lots, low traffic roadways, and
Porous friction course mixtures prepared according to the new mix design are evaluated for fracture and rutting resistance in the laboratory, as well as on an actual field test project on I-295, in Duval County, Florida.
An improved mix design approach for porous asphalt is presented which is based on the packing theory for aggregate gradation optimisation, thus reducing the post-compaction effects of the pavement by traffic loads.
POROUS PAVEMENT DESIGN AND PRODUCTION Danny Beck ... What is Porous Asphalt Compared to Regular HMA? Porous is Open graded. Open graded indicates a mix has coarse material only. Porous has no Sand. ... aggregate selection and a good mix design. This is critical to Porous Success!!!! Porous VS HMA Porous is …
Some of the specific new wrinkles in the new specification include: The spec provides guidance on all three types of permeable pavers (porous concrete, porous asphalt and interlocking concrete pavers) and compares their properties so designers can choose the best paver product for their unique site conditions.
