Since the traditional methods for measuring moisture are point specific, expensive, and/or time consuming, it is desirable to explore new devices that can provide the full coverage of the spatial variation of moisture.\nThis project will document the current state of knowledge concerning field moisture measurement during pavement foundation construction that also includes case studies that demonstrate cost savings resulting from more effective moisture measurement.  This project will also provide critical information regarding the most effective moisture measurement devices suitable for improving compaction near structures such as retaining walls and bridge abutments.  Finally, this proposal will demonstrate a prototype device capable of continuously measuring moisture during pavement foundation construction.\nIntroduction:  In a series of publications (e.g., Tatsuoka and Correia, 2018), Tatsuoka, Correia, and their colleagues showed the importance of controlling the moisture content and degree of saturation during the construction of unbound pavement layers. Failing to estimate the moisture content accurately and promptly during construction may negatively impact the proper quality control/quality assurance (QC/QA) of compacted geomaterials (Roberson and Siekmeier, 2002; Nazarian et al., 2014).  Although numerous methods and techniques have been proposed to measure moisture content, none of them have been able to deliver real-time, continuous moisture measurements that would aid the engineers in delivering more durable pavement structures.\nSeveral techniques for determining the moisture content of geomaterials have been proposed throughout the years. These techniques, which can be classified based on their approaches and measuring principles, are normally divided into direct and indirect categories (Svensson, 1997). The direct method consists of extracting a soil sample from the desired location to be investigated. The soil sample is weighed before and after drying in an oven at a maximum temperature of 105°C (220°F). This is the gold standard for measuring the moisture content. However, it is neither nondestructive, continuous, nor real-time.\nIndirect methods are based on the use of a radiation source or a probe in the soil for the measurement of moisture contents. Some examples of these methods (see Table 1) consist of the time domain reflectometry, ground penetrating radar (GPR), electromagnetic/dielectric measurements, soil resistivity/conductivity, etc. None of these methods measure the water content directly.  They each measure a parameter that is correlated with the water content in the soil. Some of these methods only provide spot measurements, some require probe insertion, while most are typically nondestructive since the soil is only disturbed during installation (Evett et al., 2008).\nSeveral techniques are still in the process of development to create automated continuous soil water content measurements in the field. Researchers around the world have been investigating these techniques to discover the most efficient method. Muller (2017) demonstrated an innovative semiautomatic approach using multi-offset GPR to achieve quantitative estimates of moisture content and layer depth predictions continuously over long lengths of the existing roads at traffic-speeds for unbound granular pavements. A 3D Noise-Modulated (NM-GPR) equipment was used for moisture content measurements by collecting a series of adjacent partially overlapping ground-coupled multi-offset measurements.
