This research study investigated the application of existing NDT technologies for measuring Should lead to increased measurement of layer moduliâa material property that can beĮstimated through NDT tests and is not included, at present, in the acceptance plan. Pavement Design Guide (MEPDG) uses layer modulus as a key material property. Furthermore, the new Mechanistic-Empirical Technologies, have been improved significantly and have shown potential for use in the Radar (GPR), falling weight deflectometers (FWD), penetrometers, and infrared and seismic More recently, nondestructive testing (NDT) methods, including lasers, ground-penetrating Little within the past couple of decades. The test methods to measure the volumetric properties have changed Variety of laboratory and field test methods that measure volumetric and surface properties of Pavement construction quality control and quality acceptance (QC/QA) procedures include a Desired resultsĪre those that meet or exceed the specifications and design requirements. The desired results are obtained to produce high-quality, long-life pavements. Quality assurance (QA) programs provide the owner and contractor a means to ensure that Nondestructive Testing Technology for Quality Control andĪcceptance of Flexible Pavement Construction NCHRP 10-65â Volume 2: Research Report June 2008 Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
