Research on the Stability Evaluation of Waterproofing Capacity of Asphalt Compound Waterproofing Layer of Underground Parking Area Upper Slab after Fire Damage

Abstract:

This research intends to evaluate the level of affect of fire damage on the waterproofing layers performance level that are applied to the upper surface layer of underground parking area slab. Samples were collected directly from the fire damage site in order to evaluate how much of the waterproofing performance is retained in the water proofing layer. As per the designed procedure of this research, the involved structures that underwent fire damage were first examined and the samples that were afflicted by the fire damage were visually inspected. The sample collected from the fire damage site was taken and compared with the same undamaged sample type in order to evaluate the difference of the former's waterproofing performance capacity. The conclusion of the research finds that despite the 250mm width concrete surface slab being subjected to intense fire damage, there was no deterioration in the waterproofing layer's performance capacity.
