horizontal tensile strains at the bottom zone of the asphalt beam, E1 is the elastic modulus of the asphalt, and f1, f2, f3, A, B are fatigue regression coefficients (Asphalt Institute, 1993; Huang YH, 1993; and Theyse et al, 1996) for crack initiation. Regression coefficients A and B are a function of the asphalt mix-stiffness.
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

Samples of asphalt mixtures were prepared at four different asphalt contents by weight of asphalt mix mass (5%, 5.5%, 6%, and 6.5%), with three replications per asphalt content. For base asphalt cement and each modifier concentration, one asphalt cement content was chosen, which met the requirement of Superpave mix design 4% air voids.

The weight of the asphalt is the gallons of converted to pounds times the percentage of asphalt in the emulsion. Using just asphalt, as in hot mix, the percentage would be 100%. For emulsions you should check with supplier, but the range is typically 55-70% asphalt. weight asphalt (lbs) = gallons asphalt emulsion per ton * 9.4 lbs/gal ...
thickness and structural value of each of the individual pavement components. The determination of alternate designs and the selection of an optimum design based on costs, conservation of materials, etc., will also be discussed. Regardless of what type of design is involved (new construction, rehabilitation, widening, etc.), the

Mar 20, 2013 · The objective of a mix design is outlined on this slide. Historically the Hveem and Marshall design methods have been used. They have been described in previous modules. No matter which mix design procedure is used that the requirements for the resultant hot mix asphalt remain the same.
Asphalt cement is the basic ingredient of asphalt emulsions. In most cases, it makes up from 50 to 75 percent of the emulsion. Some properties of the asphalt significantly affect the finished emulsion. But there is not an exact correlation between the properties and the ability to emulsify the asphalt.
The density of the compacted mix is the unit weight of the mixture (the weight of a specific volume of asphalt mixture). Density is important because proper density in the finished product is essential for lasting pavement performance. Mix properties are required to be measured in volumetric terms as well as weight.

basis for the pavement design. 2. Design variables a. Analysis period (n) – n is the period of time for which the analysis is to be conducted. Normally 50 years for concrete and 30 years for asphalt. b. Design Traffic (ESALs) – ESALs is the estimate of number of Equivalent 18 kip Single Axle
Virgin mix is recommended. Liquid asphalt content by weight for virgin mix should be 8%. If using recycled mix and the curb does not stand the liquid asphalt content will need to be raised. Recycled mix usually has too many foreign substances in it and it usually does not have enough liquid asphalt in it.

Mix Design. Mix design is the basic process of combining aggregate and asphalt binder to produce a strong durable mixture. The relationship of the volume of the mix components to the mass is shown in Figure 1. The conversion of mass to volume is done through the specific gravity of the individual components of the mix.
