Abstract

Urban infrastructure is often affected by structural and functional distress of interlocked concrete pavements, which affect the durability of urban infrastructure. This research includes a community-based field evaluation to determine the most critical mechanisms causing pavement failure and to determine the effectiveness of surface treatments. A field survey was conducted of 35 civil/pavement engineers, academic researchers and local road users. Results showed that the most common structural failure drivers were insufficient compaction of subgrade (97.1%) and unsuitable sand bedding gradation (97.2%). Moreover, surface water drainage problems (97.2%) and illegal loading of vehicles (94.3%) have a significant effect on the surface erosion. To help diminish these decrepitations, 100% of respondents stated that it is technically feasible to apply a hydrophobic Silane protective coating to lessen the water absorption and abrasion. The study offers useful guidance for optimum pavement maintenance and service life of infrastructure.
