Infra-red technology is used to heat and repair a new asphalt rejuvenation product from Milton Keynes-based Asphalt Systems International.
The firm says ASI Rhinopatch Gilsonite Asphalt Reinstatement is chemically engineered to provide a more seamless bond with surrounding pavement surface than conventional bituminous materials. Once in-situ it can be repaired by re-heating. This removes any need to dig out and reinstate the repair as pavement deteriorates over time.
Rhinopatch shows good flexibility too, the firm claims.

Piling contractor Stent and consultant Gifford & Partners have collaborated on design of continuous flight auger, large diameter and bentonite piles for construction of a 1km raft on the M60 Medlock to Irk motorway.
Using an observational approach researched by Bristol University, the partners dropped original designs for piles 350mm in section and 14m long in favour of 3,600 15m long pre-cast piles with square sections of 270mm and 235mm.
Stent also deployed CFA techniques to install 1,200mm diameter 20m long piles fully reinforced with heavy cages for construction of an overbridge. Normally piles would be installed using bentonite techniques.
Main contractor for the M60, the final link in the Manchester outer ring road, is Balfour Beatty.
