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.

Inspects and approves hot mix asphalt plants, maintains approved lists for truck bed release agents, warm mix technologies, and reclaimed asphalt shingle In-place density of asphalt pavement is a vital property which can indicate the long-term performance of a flexible pavement. It is also a primary characteristic used to measure quality during construction. Traditionally, the in-place density of HMA pavements was measured from core samples cut from the pavement after compaction. While this HMA Density Inspector Certification Program is intended to provide qualification of personnel performing density testing on Hot Mix Asphalt in New York State. Certification is valid for five years and is based on attending the two day program and successfully passing the written examination. The examination includes the following:
pavement subject to a unit price reduction for density deficiency according to Section 7020, 3.04. 2. Payment: Payment will be at the reduced unit price according to Table 7020.02 for each density of HMA pavement. If there is a density deficiency on a privately contracted
Definition of HMA In simple terms…: A mixture of asphalt binder and graded mineral aggregate, mixed at an elevated temperature and compacted to form a relatively dense
