- Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units? Well, once you have the concentrations in g/100mL you will be able to compare your values with the nutritional values given on the drink bottles’ labels). The sample of the drink was diluted 1/100 (i.e. by a factor of 100). This was an essential step in the method because, without it, the machine used to analyse the glucose concentration (spectrophotometer) would have given an error as the concentration would have been too high for accurate detection. What this means for you is that the dilution factor will need to be taken into consideration in your calculations (remember the aim is to calculate the concentration in the original drink and not in the diluted drink). You measured the concentration of their diluted drink using the spectrophotometer and their results were provided to them in the units mM (millimolar). Glucose Concentration in mM of drink =…There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units?
