ABOUT

The Strathfillan Creek Rail Bridge has four spans, each approximately 9 metres in length. The three bridge piers and the two abutments, which are constructed predominantly of unreinforced concrete, were suffering from severe Alkali Silica Reaction (ASR) induced cracking. V/Line required a remediation treatment to be designed to stabilise the deterioration.

IMPLEMENTATION

CPR Services undertook these works for VLine, the regional transport service network in Victoria.
CPR undertook epoxy crack injection works as well as the installation of CFRP plates and CFRP wraps:

• Over 1200kgs epoxy resin injection for structural crack repair
• 186 l/m carbon fibre plates into concrete internally for structural integrity to the bridge
  
• 270m2 carbon fibre wrap around piers
• 292m2 anti-carbonation protective coating
