Envirobed's Welsh roads test

A NOVEL resin alternative has been used to repair roads in North Wales in the UK. The product, supplied by Ultracrete, has been used to provide a durable, high-strength ironwork reinstatement.

Long lasting repair performance is claimed for the new Ultracrete system
A NOVEL resin alternative has been used to repair roads in North Wales in the UK. The product, supplied by 2492 Ultracrete, has been used to provide a durable, high-strength ironwork reinstatement. The cement-based resin alternative material, Envirobed HA104, was tested by the 2312 North Wales Trunk Road Agency.

Resins have traditionally been the first choice for ironwork reinstatement, due to their high performance and rapid set times.

Until now it had always been difficult to match the same performance characteristics using an alternative material. However this new product is a revolutionary, next generation, environmentally friendly bedding mortar alternative to resin-based materials.

It is supplied as a two-component system which contains a blend of special cements, polymer-graded aggregates and recycled glass. The combined components provide a high performance mortar, which can be used for depths of 10-50mm in one pass. If necessary, greater depths can be achieved by using a layer-uponlayer method.

The trial in the Pen y Clip Tunnel on the A55 trunk road was carried out to assess its performance at a location featuring sustained high traffic volumes.

The product offers early tensile strengths that provide significant resistance to heavy traffic volumes.

Brian Jones* offers some best practice and advice for getting the most from ground-penetrating radar investigations Ground-penetrating radar (GPR) is one of the most accurate non-destructive testing (NDT) methods available. To get the most from GPR surveying, it is absolutely essential to understand how GPR tools work and follow best practices when conducting surveys. Key areas to be aware o

    Innovative formwork systems have been used to construct a variety of bridge structures. Patrick Smith reports. As part of the work on Germany's new A4 autobahn near Eisenach, the contracting joint venture awarded the formwork contract for two of the three viaducts to Doka. What makes this assignment so special to the company is that although the two steel composite bridges each have very different cross-sections, the JV is using the same overslung composite forming carriage to pour the carriageway slabs of

Although the cost of fuel has dropped since last summer's high, reducing the cost/tonne of production is still high on the agenda for most quarry operators, along with improving quality.
