Questions for Agency Survey of Practice Regarding Rapid Asphalt Production/Construction Controls

The purpose of this survey is to compile information on the use and implementation of new methods/procedures being utilized to speed both the production of asphalt mixtures and the construction of asphalt pavement, as well as improve in-place pavement quality. The results of this questionnaire will be used create a data base on current practices and needs.
