ROSTMOS (Road state monitoring system)
The project objective is to develop a system for the registration / verification of road state that with high precision can monitor the condition of the road network in real-time.
The project will demonstrate how road state data can be collected and linked with other information such as weather conditions and operational measures in the form of snow clearing and gritting. It will also be shown how road state data can be used to improve the prognosis for the development in the driving conditions.

NorDust (Road dust emission, modelling and mitigation in Nordic conditions)
The project will bring together Nordic expertise in the area of road dust to further develop the modelling tools necessary for the efficient and effective reduction of road dust emissions. The project will achieve this through a set of experimental work packages looking at processes related to road wear, road dust suspension, wet removal processes, monitoring methods and to road maintenance and operation techniques. The experiments and monitoring campaigns are intended to fill in existing knowledge gaps, identified in previous studies, and the results of these experiments will be used to improve the modelling tools used for predicting road dust emissions. Typical processes to be investigated include road wear dependence on stud and tyre types, wear and suspension due to pavement properties and texture, optimising the needs for both reduced wear and noise, wet removal processes of dust and salt, road dust loading distributions and measurements, road operation impacts such as cleaning, dust binding and the contribution of traction sanding.

REHIRUP (Reducing highway runoff pollution)
The aim is that the project shall lead to improved pollutant retention efficiencies, enhanced degradation of organic pollutants, optimized multiple use of the land utilized for runoff management, and a better utilization of resources. All these goals are to be reached in an improved environmentally and economically sustainable way. Pollution control and services to local ecosystems must be seen in a perspective where the complex interactions between pollutant sources, runoff, treatment, impacts, and services are addressed holistically and secured against impacts of future climate change.

HERO (Heating Road with Stored Solar Energi)
The overall aim is to reduce accidents and improve accessibility caused by snow and ice. Furthermore, the technical design and different materials for various applications will be investigated, and the purpose is also to optimize the system performance for the road together with heat source and to develop the control and regulation of the energy demand, which along with climate forecast is of fundamental importance for the functioning, effectiveness and efficiency.

NorSIKT IP
The main purpose of NorSIKT IP is to ensure implementation of the main results in the NorSIKT I and NorSIKT II projects.
The technology develops steadily and it is a goal for NorSIKT IP to stay updated on new solutions that can supplement existing systems or replace traditional technology.
One of the aims for NorSIKT IP is to establish routines on permanent basis for calculating Nordic speed barometer and Nordic barometer for change in total vehicle mileage.

DURAPAV (Durability of pavements that reduces noise and rolling resistance)
The DURAPAV project will investigate durability of rolling resistance and noise reducing pavements through accelerated testing. The circular testing facility at VTI is seen as excellent equipment for performing accelerated testing, which can identify potential weaknesses and predict pavement failure.
The DURAPAV project will, based on the accelerated tests, seek to enhance the durability for pavement types with low rolling resistance and noise properties by optimizing the polymer distribution and mixture adhesion of the asphalt material. As the pavements need a small texture depth to provide lower rolling resistance and reducing noise, there is a potential risk of skidding problems and other surface defects. The mix design is therefore a delicate matter to secure all functional properties for the entire life time of the pavement. A lifetime that needs to be comparable with the life time of traditionally used wearing courses of 12 – 15 years.

RMMS (Road Markings Management System)
The aim of the project is to design and develop a user friendly asset management system for road markings. The purpose with the system is to provide road administrations with a robust tool for performing better maintenance strategies and secure that the resources available are used where it is most needed.

ROMA (State assessment of road markings in the Nordic countries)
The visibility of a road marking is dependent of its retroreflectivity. therefore, in order to ensure good visibility, there is a need of adequate maintenance routines. Furthermore, the road marking material must be of high quality, i.e. be resistant against wear from the traffic.
The purpose of the study is to ensure good road marking visibility. If there is a difference in visibility between two or more coutries, this result should be explained. Is the difference due to the road marking material, maintenance routines, road marking area ect.? Moreover, the result can be used to distribute maintenance funds in such a way that the road marking quality will be similar in all countries.

NordLCA (Life Cycle Analyses Tools to Assess Climate Impact of Road Building)
Reduction of climate impact is highly prioritized, but we need methods and tools that help good decisions and choices through all processes from planning to designing and construction further to operation and maintenance. Existing tools have different background in their development because of their aim. They stand well alone but would gain of cross-linking.
The Nordic countries have largely similar conditions in terms of road construction, raw materials and machinery. We therefore wish to further develop and link the respective Nordic tools, and create national adaptations.
Possible applications of the tools are:
•Environmental budget to be used by NRA internally
•Tender procedures (requirement or award criterion)
•Accounting for environment after/during construction

EPAS 2
The aim of EPAS 2 is to provide the road authorities with improved knowledge based decision making within the field of winter maintenance (equipment, driving speed and use of salt). The project should provide answers on how to re-design the salt spreaders so that improved aerodynamics will allow higher speed.
The project will develop a new mobile test unit which may quantify the discharge pattern and reproduce results over time
