Mixing and Working With Laboratory Equipment

Learn more about mixing and other ways to safely work with laboratory equipment.

Working with Laboratory Equipment

Working safely with hazardous chemicals requires proper use of laboratory equipment. Maintenance and regular inspection of laboratory equipment are essential parts of this activity. Many of the accidents that occur in the laboratory can be attributed to improper use or maintenance of laboratory equipment. This chapter discusses prudent practices for handling equipment used frequently in laboratories.

Laboratory short-term aging protocol for plant-mixed and laboratory compacted samples

It is well known that oven aging conditions (temperature and time) have significant influence on both engineering properties and field performance of asphalt mixes, and they also affect volumetric properties. Correspondingly, the oven aging temperature and time are critical to asphalt mix design, quality control, and engineering properties used for pavement design and performance prediction. This paper presents a tremendous laboratory effort to make recommendations on laboratory short-term aging protocol for plant-mixed and laboratory compacted (PMLC) specimens. To this end, various laboratory tests, including Hamburg wheel tracking test, Overlay test, indirect tensile strength test, resilient modulus test, and dynamic modulus test were performed to compare the engineering properties of PMLC specimens to those of plant-mixed and field compacted (PMFC) field core specimens at different aging stages. The test results and recommended oven aging time were presented and discussed in this paper.
