BID - Nuclear Surface Moisture Density Gauge 2005

This document is a specification for a nuclear surface moisture-density gauge used by the Texas Department of Transportation (TxDOT). The specification outlines the requirements for the equipment, including that it must be the latest model in production, new, and meet all safety regulations. TxDOT encourages manufacturers to comply with environmental standards and use recycled materials. The document also mentions the importance of quality and ISO certification. The specification describes the scope of the gauge, which is to measure in-place density and moisture content of soils and roadway base material. Examples of approved gauges are provided. The document also includes operational requirements for the gauge, such as the density and moisture range it should be able to measure and the accuracy of the measurements. The gauge should also store calibration data and standard count data. Additionally, the gauge should have a liquid crystal digital data readout capable of showing the measurements simultaneously or in separate counts. The document concludes with respondent requirements, including the need to provide a copy of their radioactive materials license.
