Investigation of spray seal pavement failure at Caloundra Tennis Centre
Built Environment Collective was commissioned to provide Civil consulting services for the Caloundra Tennis Centre Redevelopment. The project involved a 580 square metre car park extension. A two-coat spray seal pavement was determined appropriate with respect to budget requirements and infrequent light vehicle usage. Three months into the on-maintenance period the new car park pavement exhibited significant aggregate stripping. The performance of the two-coat spray seal as-constructed was reviewed to determine suitability and method of failure. Response was also provided to the sub-contractor’s claims that: 2-coat seal should not be employed for use in a carpark; the pavement performance (and failure) was indicative of a two-coat seal application. This paper compares the as-constructed two-coat spray seal with: the nominated Sunshine Coast Regional Council Specification; Austroads Guidelines; industry best practice.
