"State transportation agencies were contacted and requested to submit information on new or recently added equipment and/or new uses for old or new equipment for laboratory or field testing for quality assurance and control of highway materials. Information was received from 44 agencies. The information received from the transportation agencies is separated into two categories, equipment primarily for laboratory tests and that primarily for field tests. Each category is subdivided into groups by specific equipment or type of test. The data include 312 laboratory items and 152 field items. Costs of individual items of equipment range from $10 to $340,000. Findings are presented in the form of tables containing user agencies' experiences and viewpoints on each item."  The report for this topic can be purchased at https://www.trb.org/news/blurb_detail.asp?id=3514
