Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total ninety-three (93) to ninety-seven (97) percent by weight of the total mixture and are mixed with three (3) to seven (7) percent asphalt cement. It is manufactured in a central mixing plant where the asphalt and aggregates are heated,

Nov 20, 2016· Introduction: • Dense Bituminous Macadam (DBM) is a binder course used for roads with more number of heavy commercial vehicles and a close-graded premix material having a voids content of 5-10 per cent. 4. Why DBM? • This material has increased in popularity due to durable surface which performs almost well as in all situations.

plant, storage yards, and other facilities for producing and processing the material construction. ... (0.5%) by weight of the asphalt. Such additive material shall be of quality and grade acceptable to the Engineer. Article 2.4 Equipment A. General All equipment used on …

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.

Asphalt concrete -- also known as asphaltic concrete -- is a mixture of gravel or aggregate with crude oil residue to serve as a binder. Although asphalt concrete is the technical name, laypeople typically refer to this mixture as asphalt. The unit weight of asphalt concrete varies depending on the aggregate and is …

To calculate the weight of material needed for a project you will need to know the compacted density of the material. Density is the weight of material per volume. For example pounds per cubic foot. The density of asphalt pavement mixtures does vary depending on …

Asphalt Mixtures Calculator. Enter the width, length and thickness, then hit the "Calculate" button to calculate your estimate. You may also revise the default density value of 145 lbs/cubic ft. Actual densities may vary depending on the components of the mix.

Reclaimed Asphalt Pavement in Asphalt Mixtures: State of The Practice CHAPTER 3. BEST PRACTICES FOR INCREASING RAP USE. This chapter presents some of the current best practices for increasing the amount and frequency of RAP use regarding the management, mix design, production, and placement of RAP asphalt mixtures.

often the adjustment simply involves a modification in the asphalt content. The density produced during the mix design should not be used as the reference density since the laboratory properties will be somewhat different from test results on plant produced materials.Sometimes aggregates break …

This calculator is designed to give the volume in both cubic feet and cubic yards, and the tons of asphalt hot mix required for the form size you have entered. The tonage calculation is specific to asphalt only. In our equations, 1 cubic yard of hot asphalt mix weighs 2.025 tons, or 4050 lbs.

The maximum unit weight is also sometimes called the "solid density". This value is based on the asphalt mixture's maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF).

The ASPHALT CALCULATOR helps you to estimate The Hot Mix Asphalt (HMA) tonnage required for your job. To use the The ASPHALT CALCULATOR, simply enter the width, length, and planned nominal compacted thickness of your job. Next, click on the "SUBMIT" button. The ASPHALT CALCULATOR will estimate the tons of HMA that will be required.

This manual is the combination of three separate Hot Mix Asphalt (HMA) manuals used in the design, production, and testing of HMA for the Michigan Department of Transportation (MDOT) projects and a Laboratory and Technician Qualification program. This manual consists of the following sections:

How do I calculate the percentage of asphalt in a mix? The amount of asphalt cement in an asphalt concrete mix is based upon the total weight of the mix including the stone (aggregate) and the asphalt. In the case of cold mix made with emulsion, the asphalt cement is the amount left after the water has evaporated out. The percentage of asphalt is:

FHWA 'Asphalt Pavement Principles' YouTube Series The new "Asphalt Pavement Principles" online video series from the Federal Highway Administration highlights the innovation and collaboration that go into modern asphalt pavements. Developed with the cooperation of the National Asphalt Pavement Association (NAPA), the videos feature engineers ...

How to Calculate Asphalt Tonnage By William Hirsch. SAVE; The weight of asphalt in tons required for a paving project may be readily calculated using a few simple tools and concepts. The weight of any substance in pounds is related to its weight density or compactness. Weight density is the number of pounds of a material contained in a specific ...

Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together.

Bitumen Density Calculator. Bitumen is also called as Asphalt or Asphalt Cements. It is a sticky, black and highly viscous semi liquid/semi solid form of petroleum. It is extracted from the natural deposits. It is mainly composed of highly condensed Polycyclic Aromatic Hydrocarbons.
