Quality assurance is defined only as those planned and systematic actions taken by the agency to provide confidence that a product or facility will perform satisfactory in service. (T/F) Right Ans - False A quality assurance program serves as a skeleton or overall framework necessary for construction quality assurance implementation. (T/F) Right Ans - True Joint development and review of quality assurance specifications should include agency and industry personnel (engineers, inspectors, technicians) who are directly responsible for construction. (T/F) Right Ans - True The same six core elements required for a design-bid-build constitution QA programs are also required for design-build construction QA programs. (T/F) Right Ans - True Quality control activities include only sampling and testing. Visual inspection is regulated to the acceptance inspector. (T/F) Right Ans - False Quality control plans are project specific documents whose function is to address specific production facility and field placement processes for individual categories of work on a construction project. (T/F) Right Ans - True Acceptance is the responsibility of the transportation agency. (T/F) Right Ans - True The engineering limits are the absolute threshold values for individual test results. (T/F) Right Ans - True Quality assurance specifications typically use quality measures. (T/F) Right Ans - True Since the objective of the IA comparison is to identify discrepancies or variability in testing procedures or equipment l, IA testing is performed on split samples. (T/F) Right Ans - True 1 / 2
Dispute resolution is a formal system designed to address significant differences between agency acceptance test data and/or observations and contractor QC test data and/or observations. (T/F) Right Ans - True All agency central laboratories are required under federal regulations to be accredited through the AASHTO accreditation program (AAP).

(T/F) Right Ans - False An asphalt binder blended with water in a colloid mill is called an emulsion.(T/F) Right Ans - True Viscosity is defined as a fluids ability to flow (higher viscosity=more flowable).(T/F) Right Ans - False When exposed to air over an extended period of time, asphalt binder tends to stiffen and becomes less flexible. (T/F) Right Ans - True A PG binder with a grade of 64-27 would be used in warmer climate than a PG Binder with a grade of 70-28. (T/F) Right Ans - False A PG 64-28 may or may not be modified. (T/F) Right Ans - True The binder supplier should always be consulted for recommendations on the optimum mixing and compaction temperatures for modified binders at the plant. (T/F) Right Ans - True
