WATMOVE Water Movements in Road Pavements and Earthworks

There are 5 Work Packages:     
     
Work Package 1 will include a State-of-the-art: Literature review with the sub-divisions:      
a) Observations and results obtained in laboratory experiments and field investigations;      
b) Tests and use of models for prediction and design purposes.     
     
Work Package 2 will consider Modelling and Monitoring of water flow and moisture within pavements and subgrades. A review and survey of existing models will 
be carried out as well as evaluation of models appropriate for hydrogeological considerations related to highway design.     
Parameters for models are important and need to be investigated. Furthermore there will be an inventory and survey of technologies for measurements of water 
movement and moisture content in roads with various materials and pavement structures. Testing and validation of a model or models in full scale, as well as 
water movement monitoring could be a part of this WP as field experiments.     
     
Work Package 3 will deal with environmental aspects of water in roads. A review and classification of pollutants leaching from road construction materials 
will be done. Furthermore mechanisms and factors affecting the leaching and transport of pollutants will be studied and finally a review and evaluation of 
remedial measures will be given. This will include an inventory of methods for handling and treatment of highway drainage.     
A central issue for the leaching process in the road structure is the quantity of water infiltrating through the pavement. Over a period of time, bituminous 
pavements undergo cracking, which probably leads to very high infiltration capacity. High salt concentrations in the water infiltrating the road structure 
will affect the chemical state and mobility of metals in several ways.     
     
Work Package 4 will discuss performance-related properties. This will include an inventory and survey of water related factors relevant for an appropriate 
pavement performance. Both bearing capacity and frost actions will be studied and related to the moisture content of the pavement structures. Included in 
the investigations will be moisture versus compaction and moisture versus fines (plasticity, type etc.). Finally a review and investigation of relationships 
between laboratory and field analysis will be given. Within this WP field experiments could be a     
part to investigate relevant factors in full scale.     
     
Work Package 5 will result in the Final Report that will draw together the essence of the preceding Work Packages. It will summarise, draw conclusions, put 
forward recommendations, and set programmes for disseminating the work of the Action. Dissemination is a very important part of this task and a special dissemination 
group will be responsible for this starting relatively early in the action. This will also include hosting and participation in workshops, seminars and relevant 
international conferences during the second and third years of the Action.
