Due to the fact that 50 HMA job mix formulae (JMFs) were carried out, of which they were due to the change in the conditions of the materials for carrying out the paving execution, in which the granulometry mainly changed by the availability of the stone aggregate and the attack front at the extraction bank, their physical properties were analyzed, and 50 different Gmm values were obtained. There was a total of 586 readings of density, compaction, and air voids, implying wide dispersion of the results.  
Due to the complexity of data interpretation, it was decided to analyze the data by segment and by job mix formulae (designs) of asphalt mixtures, which will be shown in the following illustrations.  
It should be mentioned that the climatic conditions under which the data were obtained were in the month of November, for which the average temperature is 15.4 \({}^{\circ}\)C, and that the readings were made without the presence of rain, so that dielectric constant adjustment was not necessary.  
Segment 1 of the data consists of 11 JMFs for asphalt mixing, covering the distance from 234 + 500 to 238 + 700. The maximum temperature was 27 \({}^{\circ}\)C and the minimum temperature was 15 \({}^{\circ}\)C. In this segment, 161 readings were taken with the EM density gauge. Given that the core data is the average value of JMFs, the density of Segment 1 shows an increasing trend of 0.01 g/cm\({}^{3}\)/km with the mileage. The data are shown below (Figure 6):  
Next, Segment 2 includes 33 readings with the EM density gauge readings of five JMFs, located between distances 253 + 300 and 254 + 400. For this section, the weather there was a maximum temperature of 27 \({}^{\circ}\)C and the minimum temperature was 15 \({}^{\circ}\)C.  
This is the smallest interval, and representative graphs of the density data are presented below (Figure 7).

Subsequently, in Segment 3, the set of data analyzed consists of 34 JMFs of asphalt mixture with different densities, located between the distances \(293+500\) and \(307+200\). In this part, 392 density readings were taken with the EM density gauge. The density data are shown in the following graph (Figure 8). The temperature conditions for taking this data were a maximum temperature of \(27\ ^{\circ}\)C, while the minimum was \(17\ ^{\circ}\)C.
