Management of Highway Structures Complementary Guidance

Read document description

Management of Highway Structures, the code of practice for highway bridge and structure maintenance management was published in September 2005. It provides local authorities with guidance on structures management in an ever changing environment, creating a strong foundation for a positive and lasting maintenance policy. Adoption of the recommendations in this code will help the delivery of Best Value services. The UK Roads Liaison Group and its Boards recognise that highways are a constantly changing discipline and have published Complementary Guidance to the Codes of Practice. The Complementary Guidance has the same status as the Code.

Flood resilience and resistance for critical infrastructure

Read document description

This publication is the main output from CIRIA project RP913 Flood resilience and resistance for critical infrastructure provides an overview of the regulatory framework and outlines the main issues now faced by the industry in this area. A brief introduction is given to the principles of flood risk management to place flood resilience and resistance into a wider context. A range of case studies is provided that describes the lessons identified by infrastructure owners and operators who have suffered flooding problems in the past. Flood risk management for CI (critical infrastructure) across the UK is then considered with respect to flood risk assessment, adopting resilience and resistance measures and investment prioritisation. The publication states that flood resilience measures should be adopted as an integral part of individual organisations’ business continuity management processes, whole-life asset management plans and climate change adaptation strategies. CI owners need to develop long-term strategic investment approaches that allow for optimised investment decision making. The economic regulators should aim to provide a framework to achieve this objective.

TRL PRR 362 Performance of impregnants

Read document description

Since the early 1990s there has been a requirement to utilise hydrophobic pore-lining impregnants to provide additional durability on Highways Agency structures subjected to aggressive conditions – primarily arising from the use of de-icing salts. The material that has generally been used as an impregnant is monomeric alkyl (isobutyl) – trialkoxy silane. More recently alternative materials have come onto the market and the Highways Agency (HA) has updated its requirements to include new test methods to assess the effectiveness and performance of pore-lining impregnants. The purpose of these tests is to facilitate the acceptance of these alternative materials. A series of experiments was undertaken to assess the effectiveness of available impregnants for suppressing the ingress of chloride ions into concrete and their long term effectiveness in service. Laboratory tests demonstrated that the ingress of chloride ions by ponding and water uptake by sorptivity was significantly reduced by treatment with the pore-lining impregnants. By contrast, pore-blockers provided only very limited resistance to chloride ingress and virtually no resistance to water uptake. A limited number of tests were also undertaken on cores extracted from bridges.
