About this file
The document is a Chart of Test Methods for the AASHTO R18 Laboratory Accreditation Assessment involving the Louisiana Department of Transportation and Development (LADOTD) District Laboratory and Asphalt Technology (AT) Laboratory. The chart comprehensively lists standardized testing methods for aggregate and hot mix asphalt (HMA) materials, including specific gravity measurements, sieve analysis, particle shape evaluations, and compaction density testing. The document details multiple test procedures using AASHTO, ASTM, and DOTD (Department of Transportation and Development) reference standards for assessing aggregate and asphalt mixture properties.
The chart includes proficiency sample requirements for various testing categories, such as Coarse Aggregate, Fine Aggregate, and Hot Mix Asphalt Gyratory testing. The testing methods cover a wide range of technical assessments, including specific gravity determinations, absorption measurements, mechanical analysis, binder content evaluation, and aggregate particle characterization. These standardized testing protocols are critical for ensuring quality control and consistent performance standards in transportation infrastructure materials, particularly for road construction and maintenance projects.
