Introduction<\/h2>\n\n\n\n<p><span data-contrast=\"auto\">Delivery of a safe and well-maintained highway network relies on good evidence and sound engineering judgment. Asset management is widely accepted as a means to deliver a more efficient and effective approach to management of highway infrastructure assets through longer term planning and ensuring that levels of service are defined and achievable within the resources available.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">It is accepted that transport infrastructure is absolutely critical to the wellbeing and economy of the County and the wider UK and therefore the condition of the carriageway is of great importance. The National Highway Transport (NHT) surveys show consistently that carriageway condition and road safety are the most important highway services with condition being considered the most in need of improvement. If the Council is to support economic growth, and the health and wellbeing of the travelling public in Devon, it is essential that the Council ensures its highway infrastructure is fit for purpose.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Devon has the largest road network of any Local Highway Authority in England with a total of 13,000 km of road consisting of 8% A roads, 5% B, 35%C and 52% unclassified. Only 2,916 km of road are classified as urban with the remainder serving local communities within rural environments. In addition, the network is affected heavily by seasonal variations in traffic volumes with flows on roads of all types increasing significantly during the peak summer months. This contributes to congestion issues, particularly on our principal routes, and increases carriageway deterioration on our minor roads during these periods.&nbsp;&nbsp;&nbsp;&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The construction of Devon\u2019s road network is diverse ranging from designed roads constructed to modern standards to those which have evolved over many years having originated from historic tracks whose construction is often limited to various layers of surface dressing and patching. This presents significant challenge when managing the asset and maintaining the network in a safe and useable condition.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">In keeping with the recommendations of the CoP the core approach adopts a risk approach for all aspects of its highway infrastructure maintenance.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"2-inventory-and-hierarchy\">2. Inventory and Hierarchy<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-1-inventory\">2.1 Inventory<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">A detailed highway inventory is an essential prerequisite of establishing a cost effective and adequate maintenance regime.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The inventory is the foundation on which asset management is built and when analysed in combination with other information sources, for example, condition data, road casualty reports and traffic flows. It is also used in combination with intelligence gathered from stakeholders and experts to determine priorities. All of this provides crucial decision supporting information.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><b><span data-contrast=\"auto\">Inventory Set<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><td><b><span data-contrast=\"auto\">Inventory Item<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td rowspan=\"11\"><span data-contrast=\"auto\">Carriageway (Road Surface)<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span>\n<p>&nbsp;<\/p>\n<p><span data-contrast=\"auto\">\u202f<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n<\/td><td><span data-contrast=\"auto\">Central Reserve&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Central Island&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Lay-by&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Roundabout&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Kerbs&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Channels&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Level Crossing&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Cattle Grid<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Gully&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Catchpit \/ Interceptor&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/td><\/tr><tr><td><span data-contrast=\"auto\">Inspection Cover<\/span><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><em><span class=\"TextRun SCXW22799567 BCX8\" lang=\"EN-GB\" xml:lang=\"EN-GB\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\" data-ccp-parastyle-defn=\"{&quot;ObjectId&quot;:&quot;b344ad2d-151a-4395-9774-16488b9cf4fc|205&quot;,&quot;ClassId&quot;:1073872969,&quot;Properties&quot;:[469775450,&quot;Caption1&quot;,201340122,&quot;2&quot;,134234082,&quot;true&quot;,134233614,&quot;true&quot;,469778129,&quot;Caption1&quot;,335572020,&quot;1&quot;,134224901,&quot;true&quot;,201342447,&quot;5&quot;,201342448,&quot;1&quot;,469777841,&quot;Arial&quot;,469777842,&quot;Arial&quot;,469777843,&quot;Calibri&quot;,469777844,&quot;Arial&quot;,469769226,&quot;Arial,Calibri&quot;,335551500,&quot;6968388&quot;,268442635,&quot;24&quot;,335559740,&quot;240&quot;,201341983,&quot;0&quot;,335559739,&quot;200&quot;,335551550,&quot;2&quot;,335551620,&quot;2&quot;,469778324,&quot;caption&quot;,469778325,&quot;[&quot;Bullet&quot;]&quot;]}\">Fig.<\/span> <span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\">1.1:<\/span> <span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\">H<\/span><span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\">ighlight<\/span><span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\">ing<\/span><span class=\"NormalTextRun SCXW22799567 BCX8\" data-ccp-parastyle=\"Caption1\"> various inventory items that are associated with the carriageway.

that in periods of better funding, the Council has been able to make significant reductions in the amount of RED category condition carriageway, particularly on the minor, unclassified network.

repair, including carriageways. The main focus of the group is to address corporate aims, such as carbon reduction by establishing and approving a wider selection of treatments that can be used on the carriageway at various stages of the lifecycle. This may also bring about cost benefits compared to traditional forms of maintenance.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"text-decoration: underline\">Site Selection<\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;201341983&quot;:0,&quot;335559738&quot;:40,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">To inform the decision to ensure the correct design is selected for carriageway schemes the sites are investigated with the potential for core sampling along the scheme extents. Core samples are used to identify the current depth and condition of the existing pavement layers, also they are screened for the presence of coal tar.&nbsp; Where coal tar is identified, the core is fully analysed to determine whether the level is above the trigger point to classify the potential asphalt arisings as hazardous.&nbsp; The cost for the disposal of hazardous road arisings is prohibitive so the approach taken is to either design the scheme to negate the need to remove the hazardous material or where this is not possible the hazardous material is encapsulated using a recycling process.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"4-4-decommissioning-of-the-asset\">4.4 Decommissioning of the asset<\/h3>\n\n\n\n<p><span data-contrast=\"auto\">It is rare for carriageway assets to be decommissioned.

Approximate dates of previous maintenance works may be known to staff and where possible this should be considered in overall programming.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">Maintenance schemes for these roads should be planned and designed well in advance and wherever possible be of a suitable scale. This scale is likely to be impacted by reducing budgets.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">The remainder of the principal road network will have schemes developed primarily on the basis of machine survey and defect data combined with lifecycle planning. In addition to that, information gained from local teams around priorities and additional works will be taken into consideration. The aspiration is to produce schemes that address the site as a whole to reduce the need for multiple visits and increased disruption.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">An issue in the identification of structural schemes has been the failure to appropriately identify and prioritise treatment of surface course failures where the defects arising do not trigger reactive safety repairs. Use of the Scottish MCIR (Maintenance Carriageway Indicator Resurfacing) has been promising and is being used to identify future works.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">There is a need for reactive programming of failures either structural or surface which may be established through either survey or local report. Whilst these frequently do not generate safety defects, areas of delaminating surface compromise ride quality and can have a major impact on 2 wheel users. Surfacing schemes will be developed using a combination of MCIR indicator, reports of neighbourhood teams verified by site inspection. This means that some sites could be introduced to the programme at short notice. With reduced funding such occurrences of programme change will become more frequent, impacting more effective long-term planning.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<p><span data-contrast=\"auto\">\u2018Wet and dry\u2019 skid sites identified by analysis of the SCRIM survey will be programmed and wherever possible integrated with the maintenance programmes.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><span data-contrast=\"none\">The Local Asset Capital Programme (LACP)<\/span><span data-ccp-props=\"{&quot;134245418&quot;:true,&quot;134245529&quot;:true,&quot;201341983&quot;:0,&quot;335559738&quot;:40,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/h5>\n\n\n\n<p><span data-contrast=\"auto\">Devon County Council has looked to break down some of the historic budgetary silos by introducing the Local Asset Capital Programme.

This will place greater pressure on Revenue budgets and also lead to more claims, reduced customer satisfaction and reputation damage or the Council. Also, restrictions on the Revenue budgets have also placed strain on appropriate asset management. With less capacity to undertake cyclical work on the carriageway and associated assets, the expected lifespan of the carriageway is often reduced, bringing about interventions such as safety related repairs at a much earlier stage.&nbsp;<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:240}\">&nbsp;<\/span><\/li>\n\n\n\n<li><b><span data-contrast=\"auto\">Increased Costs<\/span><\/b><span data-contrast=\"auto\"> \u2013 Linked with budgets is the increase in costs to undertake the required work.
