Impact of Crown Crack Width in Load Carrying Capacity of Cementitious Spray Applied Pipe Linings
Publication: Pipelines 2022
ABSTRACT
Spray applied pipe lining (SAPL) is used by Departments of Transportation (DOTs) as a trenchless technology method to renew deteriorated gravity storm conduits and culverts. Cementitious SAPLs can increase the structural capacity of the deteriorated culverts. Previous studies have shown that the cementitious pipes are able to heal the hairline cracks (crack width of less than 0.01 in.). After crack formation, the healing process, also called autogenous healing, initiates by exposing the un-hydrated cementitious particles in the liner matrix to moisture. Currently, loads that generate 0.01-in. crack width is used as a benchmark for the liner thickness design. The goal of this paper is to measure the corresponding truck load that generates the 0.01 in. crack width on cementitious SAPL through a set of large-scale laboratory testing. To achieve this goal, three 60-in. diameter invert-deteriorated corrugated metal pipes (CMPs) were buried under 2 ft of soil cover in a soil box. Then, CMPs were renewed with cementitious SAPL and were subjected to the static vertical load using a hydraulic actuator. During the load application on the soil surface, the crown of the SAPLs were monitored by high resolution digital cameras, and the crack widths were measured using the digital image processing method. The results showed that thicker SAPL liner can resist larger amount of live load with lower crack opening width.
