Since dolomites are commonly used in hot mix asphalt in Indiana, the ignition oven cannot be used with some mixes or in some parts of the state where they are prevalent. Research was needed to establish a modified ignition oven test procedure that would allow for the accurate binder content
Nov 24, 2010· Best Answer: The density of Hot Mix Asphalt (HMA) may vary, but essentially averages roughly 148 pounds per cubic foot. Given: 1 cubic meter = cubic feet 1 cubic meter = cubic yards Then 1 cubic meter of Hot Mix Asphalt (HMA) weighs about: ( cu ft) x (148 lbs./ ) = 5227 lbs 148 lbs/ cu ft.

Hot Mix Asphalt Plants General12,23,4243. Hot mix asphalt (HMA) paving materials are a mixture of wellgraded, highquality aggregate (which can include reclaimed asphalt pavement [RAP]) and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA.
Jul 04, 2007· How do you calculate the density of hot mix (asphalt) just as it is loaded on trucks and before compaction.? the bulk density of the asphalt will increase after it is compacted by heavy want to know how to calculate the bulk densty if i know the densities of the aggregate and the density of the bitumin in the also want to ...
Asphalt density (weight of material per volume) is one of the most important parameters used in calculations to determine the quality and quantity of asphalt needed to pave roads. To calculate the weight of material needed for a project awareness of the .
CONTRACTOR: PERIOD: TO (BEGIN DATE) (END DATE) PLANT LOCATION: PLANT CERT. NO. PLANT MIX PRODUCED IN ACCORDANCE WITH SPECIFICATIONS. MIX TYPE JMF NO. TONNAGE REMARKS THIS IS TO CERTIFY THAT ALL HOT MIX ASPHALT TONNAGE LISTED ABOVE WAS PRODUCED IN ACCORDANCE WITH THE PROVISIONS OF THE NCDOT QUALITY MANAGEMENT SYSTEM FOR ASPHALT PAVEMENTS.
This calculator will estimate the number of tons of asphalt/hot mix that will be required. This estimate is based on a density for the mix of 150 lbs per cubic foot. Please note that densities will vary somewhat between different mixes, but this value is a standard "rule of thumb" for estimating.
Apr 08, 2013· (II) WMM(Wet mix macadam) road construction: Aggregates used are of the smaller sizes, varies between the mm to 20 mm sizes and the binders( stone dust or quarry dust having PI(Plasticity Index) not less than 6% ) are premixed in a batching plant or in a mixing machine.
How to Calculate the Spread Rate in Asphalt Paving. Correctly calculating the amount of material that is required to complete the project is essential to a successful asphalt paving assignment. On a paving project, asphalt paving material brought to the project site is measured in tons. You can calculate .
HMA PRODUCTION MANUAL SECTION 2: CERTIFICATION PROCEDURE OF HOT MIX ASPHALT (HMA) PLANTS HMA FACILITY 33 (Rev. 2017) proportions. o Aggregate The Contractor shall provide means for diverting and weighing the aggregate for a time period not to exceed five (5) minutes.
ATT17, Part I Calibration Overview. Calibration Overview. The purpose of the plant calibration is to ensure that the plant accurately proportions the asphalt and aggregate. The belt scale, test weights and cold feed bins are part of the aggregate system and require calibration.
Get Solution. The WMM is a specification in which well graded aggregate is mixed with water in a mixer and the mix is laid by a paver and rolled by a roller. Two gradings are used, one with graded aggregates below 53 mm (40 mm nominal size) and the other with aggregates below mm .
how much does a cubic foot of cold mix asphalt weigh. weight of asphalt concrete per cubic foot Typical finished and compacted asphalt concrete weighstolbs per cubic foot. The density depends on how compact it is and what type, size, and percentage of aggregates are used.

Summary. HMA mix design is a laboratory process used to determine the appropriate aggregate, asphalt binder and their proportions for use in HMA. Mix design is a process to manipulate three variables: (1) aggregate, (2) asphalt binder content and (3) the ratio of aggregate to asphalt binder with the objective of obtaining an HMA...
Volumetric of HMA • Asphalt viscosity ... – Calculate the Percent Voids in Total Mix for the Mixture – Calculate the Percent Voids in Mineral Aggregate for the Mixture – Calculate the Percent Voids Filled with Asphalt for the Mixture – Calculate the Dust/AC Ratio. Volumetric Analysis of HMA Mixtures 47
The density of asphalt is very related to the Mix Design of Asphalt. But commonly it assume ton = to 1 cubic meter. Hot Mix Asphalt weights vary based on the mix design, but 148 lbs. Per cubic foot is a good average. So, 2000 lbs divided by 148 lbs would be about .
Section 400—Hot Mix Asphaltic Concrete Construction. Page 36 When the Plans specify a thickness, the Engineer may take as many cores as necessary to determine the average thickness of the intermediate or surface course. The Engineer shall take a minimum of one core per .
Nov 20, 2016· • Less control is required for coldmix preparation with a distributor and motorgrader operation. But possibilities for as great a control as for hotmix asphalt are present in a plantmix operation. However, many plants used for producing cold mixes do not use or have all the means for maintaining close uniformity of control.
