In order to prevent the heavy road trains vibrating these structures the tram track foundations will be cast onto a floating slab structure in order that the imposed dynamic loadings are absorbed before they can cause damage to the surrounding areas. RAB Associates were consulted at the design stage, with a view to overcoming the problem of these loadings being transferred to the tarmac surfacing and bringing about rapid deteriation. Their solution was to install ‘PERMATRACK H’ heavy duty road joint... Click here to read more... |
