TL;DR: In this paper, three types of models have been used to study multilayered pavement structures: plane strain, axisymmetric, and three-dimensional (3-D).

TL;DR: This study investigates temporal and spatial variability of the Relative Accident Risk (RAR) due to rainy conditions across Texas during the year 2015 using a Crash-Based Matched Pairs Analysis (CB-MPA) approach using an hourly time scale to shed light on future paths toward more detailed applications of high-resolution environmental data in crash risk analysis.

TL;DR: In this article, a linear programming model is proposed to optimize excavation and paving services, and the borrow pit materials are allocated in the most economical way, and it is possible to incorporate more inputs like materials mix.

TL;DR: In this article, the use of pavement scores by states, including the rating methods used, the score scales, and descriptions, if the scores are used for recommending pavement maintenance and rehabilitation actions, how the scores were computed, the distresses that were used for generating the scores; the sampling method; the survey frequency; and each state agency's legislative or internal goal.

TL;DR: A new economically sound methodology for assisting with equipment replacement at Texas DOT that takes full advantage of Texas DOT’s comprehensive equipment operating system database, can prioritize the units on the basis of comparisons among all units within any desired class of equipment, and uses life-cycle cost trends as a replacement criterion.
