Abstract Asphalt superpave volumetric design and compaction tests provide engineers with the data for what type of asphalt should be used in specific climates and traffic conditions. The objective of this lab was to perform standard laboratory tests on compacted hot mix asphalt (HMA) mixtures to determine the effect of varying design mixes and materials on the degree of compaction and percent air voids in compacted bituminous samples. The specimens were recorded for their dry weight, weight submerged under water, and the saturated surface dry weight . The results showed that the top-virgin specimens were about the lightest specimens submerged under water, and the base-virgin specimens were the heaviest. The results were used to calculate the bulk specific gravity of the asphalt mixture, percent water absorbed, percent compaction and the percent air voids for each sample. The average and standard deviation for all of the samples were used to compare average results from different design mixes and if the samples were within PennDOT’s acceptance criteria. 3

Introduction Hot mix asphalt is a material that is used consistently in engineering highways and roads. Different types of asphalt mixes are used depending on the different climates and traffic. Percent compaction and percent air voids are factors that an engineer should consider when designing a roadway in a certain area . The objective of this lab was to perform standard laboratory tests on compacted hot mix asphalt (HMA) mixtures to

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
