The Use of Non-Nuclear Devices for Quality Assurance

项目名称：	The Use of Non-Nuclear Devices for Quality Assurance
摘要：	The Arkansas Highway and Transportation Department (AHTD) currently uses nuclear devices for quality assurance measurements of subgrade density, asphalt density, and asphalt mixes. The nuclear density gauge does not evaluate the strength of the subgrade or the structural uniformity of the lift compacted. If the Department's goal is to seek a modulus based mechanistic design and performance specification for state highways then non-nuclear devices need to replace the nuclear devices for all quality assurance tests related to subgrade compaction, asphalt content and density. Implementation of the devices in the construction field will save engineers and inspectors time because the new devices are relatively quick and do not require special handling and storage. The use of a non-nuclear device will save the Department time and money.
