The project was designed with the objective of comparing the cost and effectiveness of three drainable bases containing of 100% crushed PCC, 100% virgin aggregate,or a 50 - 50 blend of each. This study was implemented to determine if the degree of leachate would increase or decrease as compared to the previous year. And whether the leachate would accumulate to the point that it threatens the drainage performance of the pipe and ultimately the durability of the pavement structure. An optical camera was used to evaluate the condition of the 4" perforated pipe used in the edge drain system and will be discussed later in the report.
