Cost Comparison
system  26. July 2013 at 13:01   more

Project Background


The HM Treasury (HMT) Public Value Programme is seeking productivity improvements and improved efficiency across all Government Departments. A CEDR report published in 2007 that looked into the cost of delivering new roads, implied these were highest per kilometre in the UK compared with most other European countries. HMT have been critical of the apparent expensive delivery of road schemes and they, together with DfT expect us to explain these differences. A commitment has been made by MP and NetServ Directors to DfT and HMT to undertake this comparison in 2009/10.

A qualitative report undertaken by the Highways Agency titled European Highway Costs was published in 2008. That research...
Deformation of Thin Surfacing
system  26. July 2013 at 13:01   more

Project Background


Acceptable limits of deformation of thin surfacing as measured under the former British Standard wheel track test method were well established. Equivalent values are needed for tests carried out to the European standard BS EN 12697 - 22




Project Objectives


To determine acceptable limits of deformation for thin surfacing materials used in road construction as measured under the test methods defined in BS EN 12697 - 22




Project Summary


New limits of deformation for thin surfacing materials were determined and recommended for inclusion in Specification for Highway Works

Electronic transfer of desk study information
system  26. July 2013 at 13:01   more

Project Background


Information to follow.




Project Objectives


The research is to be focussed on how the geotechnical hazards and risks identified in the desk study, derived form base data sets and information sources, are communicated. Currently there is no standard format for the presentation of the geotechnical hazards or geotechnical risk register. It is suggested that a standardised Geographic Information Systems format or similar needs to be identified / developed to allow the information presented in Preliminary Scoping Study Report to be displayed in a spatial manner as well as a report format. This format would potentially be specified as the 'delivery format' for 3rd...
Environmental credentials for the Asphalt Industry (Collaborative Research)
system  26. July 2013 at 13:01   more

Project Background


The collaborative research programme funded jointly by the Highways Agency (HA), Quarry Products Association (QPA) and Refined Bitumen Association (RBA) has for many years provided a excellent useful forum for both undertaking and a route for implementing research and policy with support from both the HA and Industry (QPA and RBA).

Two topics have been identified for research:
Task 1. Asphalt surface performance (skidding)
Task 2. Development of a Sustainability Management System for asphalt and asphalt related products.




Project Objectives


Task 1. Asphalt Surface Performance (skidding)
The process of reaching equilibrium skid...
Grooved Concrete & Skid Resistance
system  26. July 2013 at 13:01   more

Project Background


There are sections of trunk roads/motorways where the skid resistance of the concrete surface is below investigatory level, and there are significant numbers of wet skid accidents occurring. To overlay the concrete is both expensive and disruptive, due to the high level of non-pavement works (i.e. raising barriers, ironwork, etc). However, longitudinal grooving of the concrete surface is an effective maintenance treatment, used in other countries, for improving skid resistance. A trial of a longitudinal grooving method has been carried out on the A12 at Chelmsford. This could be a low cost solution to this problem if it is shown to satisfactorily improve skid resistance.



CIRIA Guide to Implementing Lean in Construction
system  26. July 2013 at 13:01   more

Project Background


Lean has spread in popularity in recent years but it has been felt that there was a need for guidance specifically targeted at construction. CIRIA (Construction Industry Research and Information Association) led a collaborative project to provide a set of guides aimed at a construction audience. This was a follow up to their previous guide 'Build Lean'. However, while 'Build Lean' discussed the case for introducing Lean to construction organisations, this new set of guides covers the practicalities of embedding Lean into construction organisations, with each of the six guides covering a different aspect. The Highways Agency was one of the collaborators, part-funding the project and participating in the...
Assessment of Surface Disintegration Phase 2
system  26. July 2013 at 13:01   more

Project Background


The development of an optical method for the measurement of the loss of aggregate from road surfaces.




Project Objectives


To assess whether 3D camera imaging would be a suitable technique to measure the loss of aggregate from a road pavement surface.




Project Summary


Further development of optical anaylsis techniques and the aquiring of trial data from a variety of road pavement surfaces.
Extreme Cold Treatments
system  26. July 2013 at 13:01   more

Project Background


The Net­work Man­age­ment Solu­tions (NMS) Team is one of three teams mak­ing up the Net­work Oper­a­tions and Man­age­ment Pol­icy Group within the High­ways Agency’s Net­work Ser­vices Direc­torate. The NMS Team research, develop and deliver pol­icy, advice and tech­niques to improve the oper­a­tional per­for­mance of the strate­gic road network.




Project Objectives


The National Win­ter Ser­vice Research Group (NWSRG) has pub­lished advice regard­ing the use of alter­na­tive ice treat­ment mate­ri­als for spread­ing at extreme cold tem­per­a­tures when the use of salt is likely to be ineffective.

Optimum Interventions for Thin Surfacing Maintenance
system  26. July 2013 at 13:01   more

Project Background


Thin surfacing course systems are used to surface the majority of the HA's road network. They can reach the end of their serviceable life in quite a short time from the first observations of distress (6-months to 2 years). Recent improved guidance has been published in IAN157 to help maintaining agents observe the warning signs that the end of serviceable life is being reached.




Project Objectives


To understand if maintaining agents were taking TSCS replacement schemes to value management process at the correct time. To establish if condition survey information held in HAPMS would assist agents in providing a warning when the end of service life is being...
