No rule of thumb answers to your question, but two issues should be considered: Generally speaking, there are no unique problems with using polymer modified mixes as RAP. testing. Summarily, the constituent-mineral gravities provided a basis for classification and areal differentiation--that is, grouping and averaging 0. W = dry loose unit weight of chips, pcf (see T 19M/T 19, Section 12 on shoveling); 62.4 = unit weight of water, pcf G = dry bulk specific gravity of chips (see T 84 and T 85); T = traffic correction factor from Table 1; V = pavement surface correction factor; and R = emulsified asphalt residue, expressed as a decimal, e. g., 0.65 = 65 percent On the other hand, if air voids fall below 3%, there will be inadequate room for expansion of the asphalt binder in hot weather and when the void content drops to 2% or less, the mix becomes plastic and unstable. Establishing a value based on results achieved on a project-site test strip. Reheated samples can be utilized to give an overall check of the original sample results. What is the unit weight of base asphalt? The Asphalt Shingles: The shingles weigh 2.5 lbs per square foot of surface area. Example: 96% of the Marshall unit weight. There are several ways to establish density targets. for the details of density testing requirements. laboratory density results, a minimum target density unit weight (PCF) is calculated that corresponds to 93 percent density. Another way to look at it is this: In a 6000 lb. in Table 1055.04-1 in. Mix temperature is dependent on the grade of asphalt used in the mix. This item includes placing a surface If a warranty was applied to a project, a more conservative approach – such as the use of blending charts – might be taken. Laboratory Prepared Asphalt Mixture Specimens. Refer to Supplement 1055 for the details of density testing requirements. asphalt plant and the District Lab Monitoring Team’s verification of the The low temperature grade is one grade lower than the binder grade required for a virgin asphalt”. This is dependent on many factors, such as stiffness of the original mixture, age of the mix (gets stiffer over time), temperature of the mix during loading, loading itself, duration of applied load, etc. test should represent one-half of the day’s production. While there are an infinite number of questions that can be asked, we compiled a list of those questions that have been directed to us the most. The maximum unit weight is 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 624 pounds per cubic foot (PCF). Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified for proper mixing and compaction. During order to have a minimum 93 percent mat density. the testing for compliance. After a plate or hopper sample is obtained, it should be packaged to plant sampling and verification for acceptance, the specifications require The maximum unit weight is also sometimes called the “solid density”. in the unit weight (pounds per cubic foot = PCF) as Too thin a mat does not have sufficient workability, and too thick a mat may be unstable.
