The purpose of this Sabita manual is to establish a common base for the design of asphalt mixes in South Africa. The intention is to advance the move towards performance-related specifications for the design of asphalt pavement materials, which started with the publication in 2001 of the Interim
be 67% for design traffic levels < 0.3 million ESALs. 3. For 4.75 mm mixtures, the specified VFA range shall be 7% to 6 79%. 4. For OG9.5 mm, OG19.0 mm, OG25.0 mm mixtures, VFA is not applicable. 401.06 Recycled Materi als Recycled materials may consist of reclaimed asphalt pavement, RAP, or reclaimed asphalt shingles, RAS, or a blend of both.
Asphalt Plant (American Specs.) New Generation Drum Mix Asphalt Plants:. Five models with production capacities ranging from 30 to 120 tph. Stationary Strongly Built Plants. Plants are well built to meet tough working conditions, constructed of heavy duty steel and high Drum Mixer. Drum mixers
a balanced mix design asphalt specification in Missouri. At the onset of the study, a detailed climatic study was conducted. This research task produced data that can be used in the future to tailor the performance-based specification developed herein for the various climatic regions that exist in Missouri.

11.1 Hot Mix Asphalt Plants 11.1.1 General1-3,23, 392-394 Hot mix asphalt (HMA) paving materials are a mixture of size-graded, high quality aggregate (which can include reclaimed asphalt pavement [RAP]), and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA. Aggregate and RAP (if used) constitute over 92 percent
Quality: Dry and free from lumps, clay, organic matter or other material deleterious to asphalt. Materials: Added mineral filler to comply with table 3 of AS 2150. May consist of hydrated lime, fly ash, portland cement, flue dust from the manufacture of portland cement, asphalt plant baghouse fines or other approved material.
Asphalt aggregates are easy to mix and customize. There are hundreds of potential mixes that could be made to meet any specific asphalt need. Many asphalt contractors have their own asphalt production plants in order to better create solutions for those needs. …
The design of a porous pavement can be broken down into location, hydrology and structural design. This brochure will not address hydrologic design, as this should be performed by a licensed engineer proficient in hydrology and stormwater design. The general guidelines for the porous asphalt pavement design are: n Consider the location for porous
Dec 08, 2003 · Develops and maintains statewide Hot Mix Asphalt (HMA) related policies, procedures and specifications for directing implementation of the statewide HMA mixtures program. Inspects and approves hot mix asphalt plants, maintains approved lists for truck bed release agents, warm mix technologies, and reclaimed asphalt shingle processing facilities.
Asphalt Mix Design and Quality Control Software Management System StonemontQC includes powerful asphalt mix design and quality control features for asphalt producers. StonemontQC aggregate and asphalt capabilities are completely integrated thus allowing mix component properties to be easily updated or substituted from aggregate plants.
The EPA announced that asphalt plants are no longer on its list of industries considered major sources of hazardous air pollutants. Asphalt design has evolved in recent years to the point that we can provide a pavement structure that will perform in any condition. Ultimately, the goal of …

Asphalt pavements may be referred to by several names. In different trades and sections of the state it may be referred to as bituminous concrete, hot plant mix, asphalt concrete, blacktop, hot mix asphalt (HMA) or warm mix asphalt (WMA). Asphalt pavements arecomposed of crushed aggregates glued together to form a solid mass by asphalt binder.
