Highways England today paved the way for improved road building with the much anticipated release of the first suite of new design standards.

皇冠体育app publication of the first sections of the new 鈥楧esign Manual for Roads and Bridges鈥� (DMRB) will ensure roads are designed, built and maintained to the very highest and safest standards.

Accepted as the cornerstone of the delivery and management of motorway and all-purpose trunk roads across the UK, and a respected document worldwide, the DMRB was first published in 1992.

Highways England, the Government company responsible for maintaining, operating and improving the country鈥檚 motorways and major A roads, is currently updating it to make it clearer, more consistent and easier to understand and implement. 皇冠体育app update puts design requirements at its core and it will also make it easier to incorporate developments in design best practice. This will result in greater efficiency and innovation throughout the lifecycle of the assets, fewer departures from the requirements, and reduced time and associated cost.

Highways England Chief Highway Engineer, Mike Wilson said:

鈥淭his is an exciting time for the highways sector as we continue to successfully deliver the record 拢15bn investment in roads. 皇冠体育app updated DMRB documents mark a historic moment for the design of the UK鈥檚 motorways and major A-roads.

鈥淚 would like to thank the Devolved Administrations and our supply chain who have supported this significant review, which will ensure our roads are designed, built and maintained to the very highest, safest standards for the millions of drivers that use these roads every day.鈥�

皇冠体育app first four documents of the updated 鈥淒esign Manual for Roads and Bridges鈥� (DMRB) are:

• Introduction to the Design Manual for Roads and Bridges
• Requirements for safety risk assessment
• Use of Compressive Membrane Action in Bridge Decks
• Management of Corrugated Steel Buried Structures

Experts at Highways England began the task of updating the complete suite of over 350 documents and associated interim advice notes (IANs) that make up the manual in April 2017 with the review due for completion by March 2020. This is a specific requirement of the Protocol attached to the Highways England Licence as part of the Government鈥檚 Road Investment Strategy.

Changes in the updated document include:

• a new structure of the volumes to be aligned to asset life-cycle stages, from appraisal to design up to disposal
• new numbering systems of documents reflecting the relevant asset life-cycle stage and the specific discipline covered by the document
• new style of individual clauses to make a clear distinction between requirements and advisory material
• incorporation of interim advice notes (IANs) into the DMRB as relevant
• consolidation of DMRB 鈥楢鈥� (advisory) documents with related 鈥楧鈥� (design) documents
• introduction of National Application Annexes attached to the DMRB to cover the specific requirements of the Overseeing Organisations

Several leading UK consultants have supported Highways England with the update, and a new set of drafting rules has been used, which follows best practice from national and international standardisation organisations.

皇冠体育app updated DMRB supports Highways England鈥檚 vision.

皇冠体育app DMRB re-drafting is being completed using a revolutionary online authoring tool purposefully built for the refresh of the document. This signals an important move to digital technology and unlocks the potential of digital innovations.

皇冠体育app updated DMRB documents will be released in phases with completion due by March 2020.
