Stationing This method outlines the procedure for determining the random location of HMA Density testing sites using stationing. This four-day course is designed for technicians and their supervisors who have responsibility for the density control on soil subgrade and aggregate bases. The course introduces the theory of compaction on various materials, and provides training using MDOT density control tests, procedures and Electric density gauges are relatively new on the market (in the last five years). Accurate calibration of these devices is essential for their proper use. Although percent air voids is the HMA characteristic of interest, measurements are usually reported as a measured density in relation to a reference density. another method of recycling existing HMA and concrete surfaces by utilizing existing material and increasing the load carrying capacity of the resulting new pavement. 5. DENSITY Density is a ratio expressed by the formula D=W / V or density equals the weight of material divided by the volume it occupies. A simple example is the density of water.

Anchor: #i1013899 Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i1013905 6.1 General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between 300-350ºF) in an asphalt plant.

This procedure includes: 1. Selection of pavement core samples 2. Selection of density gauge test locations for 60 and 70 Series compaction specifications 3. term durability of a longitudinal joint as the density achieved along that joint. Equally,e th most difficult condition to achieve high density in HMA paving is also along a longitudinal joint in an asphalt pavement. Consequently deterioration of longitudinal joints in HMA is one of the major distresses facing agencies. Intelligent Compaction in Construction of Hot Mix Asphalt. Intelligent compaction rollers are used in compaction of hot mix asphalt for breakdown and intermediate compaction for method compaction process and for density required HMA.
