This procedure includes methods for determining the in-place density of the Hot Mix Asphalt (HMA) pavements constructed under 50, 60 and 70 Series compaction specifications. This procedure includes: 1. Selection of pavement core samples 2. Selection of density gauge test locations for 60 and 70 Series compaction specifications 3.
DensiCheck TX from HMA INSTRUMENTATION is a cost-effective solution for monitoring the liquid concentration and density in a wide variety of applications. An in-line sensor and integral transmitter, the DensiCheck TX from HMA INSTRUMENTATION provides a continuous output of concentration to enable processes to be automated and optimised. HOT MIX ASPHALT WHAT IS HOT MIX ASPHALT? Hot mix asphalt may be referred to by several names. In different sections of the state it may also be referred to as bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total The Hot Mix Asphalt Paving Inspector Certification Course is designed for those individuals responsible for the inspecting, sampling and testing of hot mix asphalt in the field. Suggested participants would include contractor and supplier quality control personnel, consultants, testing firms and agency inspectors responsible for the quality and placement of hot mix asphalt. Cost: $575.00 for In those situations where the longitudinal joint is a Type 2 the entire adjoining HMA mat being paved will be subject to density requirements in accordance with 12SP-501U Superpave Hot Mix Asphalt Percent Within Limits or 12SP-501V Superpave Hot Mix Asphalt Percent Within Limits Hot Mix Asphalt (HMA) Quality Assurance . SCDOT Designation: SC-M-400 (07/07) 1. SCOPE. Base field acceptance of hot mix asphalt (HMA) mixtures on asphalt binder content, air voids, voids in mineral aggregate (VMA), and in-place mat density of the pavement.

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

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 Apr 01, 2017 · (2) If three or more density intervals remain, they shall be considered a density sublot. (h) Density Test. A density test shall consist of a core taken at a random location within each density interval. When establishing the target density, the HMA maximum theoretical gravity (G mm) shall simulate the in-place density of HMA after it has endured several years of traffic in the roadway.
