  • Abstract:
    The Indiana Department of Transportation (INDOT) conducts chip seal operations on state highways to prolong the life of the road. The  ; chip seal operation is labor, equipment and material intensive. A typical chip seal operation may involve 35 or more INDOT employees  ; including truck drivers, flagmen, and equipment operators (brooms, rollers, aggregate spreader, and distributors).  ; This project was launched to better understand and document variations in how each of the six INDOT districts, approach the  ; planning and execution of their respective  chip seal operations. The goal was to identify areas in the operation where there were  ; differences between districts and to determine best practices that could be shared among the districts.  ; Two observers joined the chip seal operations in all six districts. The observers spent a total of 10 days with the chip seal crews (2  ; days each with the crews from Fort Wayne, La Porte, Greenfield, and Seymour and 1 day each with the crews from Vincennes and  ; Crawfordsville). One additional day was spent in Crawfordsville observing the Fog Seal operation that takes place a few days following  ; chip seal.  ; During the initial phases of this project, many differences were observed regarding various aspects of the operation including the  ; stone and equipment used, truck loading procedures, traffic control, and covering raised pavement markers (RPNs).   ; These observations were shared with key stakeholders on November 4, 2013 and with a second group of stakeholders on January  ; 22, 2014. With the help of stakeholders, best practices were identified from the observations and a list of 14 recommendations was  ; created to be shared across all districts. A series of meetings were then scheduled to share the recommendations with each district and  ; to determine which recommendations they were interested in piloting.  ; The three ideas found during this project that provide the greatest opportunities for improving the overall operational efficiency of  ; the chip seal operation are (1) the importance of closing roads during chip seal whenever possible, (2) the importance of choosing the  ; best locations for stone stockpiles and oil tanker deliveries, and (3) the importance of fully loading dump trucks to their maximum safe  ; and legal limit.
