refining. The petroleum asphalt flow chart (Figure 1-1, page 1-2) shows generally the flow of crude petroleum through a refinery. Residue from this fractionating process is the heavy component of crude petroleum, which includes asphalt. However, further refinement is necessary to produce asphalt cement.

graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the mixture by weight and 75 to 85 percent by volume. Figure 2-1.Petroleum Asphalt Flow Chart for Emulsified and Cutback Asphalts.

Introduction to Asphalt Cements and Emulsions

Asphalt Cement Handling •Asphalt cement does not readily flow at ambient temp. –Reduce viscosity (measure of resistance to flow) to pump, mix, and use in production/construction of pavements •Three solutions –Heat (most prevalent) –Dissolve in solvent (cut-back asphalt) –Disperse in water with chemicals (asphalt emulsion)

Cement Manufacturing Process Flow Chart. In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone.

they may be in a position to evaluate asphalt cements at 140° F and 275° Fin terms of kinematic viscosities. 2. The viscosity requirement at 275° F for asphalt paving cements should be increased 50 to 60 percent over those now stipulated by the Asphalt Institute. The present and proposed limits are as follows: Penetration Grade 60-70 85-100

Trouble-Shooting Asphalt Content Problems

For the asphalt flow rate to be stable the scale signals must be stable. Finding the root cause of the scale signal instability problem will typically “solve” the asphalt content problem. − If the asphalt meter flow rate is the only erratic reading, suspect a mechanical or electrical flow control problem. The control system is probably having trouble controlling the flow of the asphalt cement.

How asphalt cement is made - material, used, processing ...

Asphalt paving mixes made with asphalt cement are usually prepared at an asphalt mixing facility. There are two types of asphalt mixes: hot-mix and cold-mix. Hot-mix asphalt (HMA) is more commonly used while cold-mix asphalt (generally mixes made with emulsified or cut-back asphalts) is usually used for light to medium traffic secondary roads, or for remote locations or maintenance use.
