A key element in a highway maintenance management system is a means to establish an ordered list of those sections most in need of repair. Developing such a list requires a method of measuring and analyzing existing conditions to judge which system c

From the 1990s to now, transportation maintenance quality assurance (MQA) programs have been developed to ensure that maintenance quality is being achieved. MQA programs must be capable of detecting insufficient maintenance efforts, poor material per

Computer simulation studies were performed to evaluate the accuracy and precision of the estimators for three quality measures: percent within limits (PWL), average absolute deviation (AAD), and conformal index (CI). Sample sizes of 3, 5, and 10 were

Computer simulation, using samples of size 3, 5, and 10, was used to evaluate the percent within limits (PWL) estimates for populations with skewness coefficients from 0.0 to ±3.0. The average bias and variability were then determined for the 10,000

At a time when there is great interest in developing performance-related specifications incorporating multiple quality characteristics and several highly complex approaches are under development, it is questioned whether these procedures will be capa

The vast majority of states, as well as many local agencies, now use statistical end-result specifications to encourage high-quality construction by awarding payment in proportion to the level of quality received. Because many of the specification pr

Testing of New Jersey’s first acceptance procedure for hot-mix asphalt pavement designed by the Superpave method began in 1998 with the construction of a series of pilot projects. A distinct feature of the prototype specification was the use of a c

With the continuing interest in performance-related specifications and the development of software packages to compute the appropriate level of payment associated with variable levels of quality, there is a need for a simple, easily understood method
