Road construction and rainwater management

• know and apply relevant soils and road cover materials
• design and calculate the road structure and pavement
• design and calculate the road drainage
• evaluate if rainwater from roads and other surfaces is of environmental reasons suitable for delay, infiltration and/or discharge to recipients
• design and calculate pavements that are suitable for delay and/or infiltration of rainwater
• plan tender and construction of road and pavement
• plan operation and maintenance of a road
• know and use methods for local treatment of rain water
• calculate and evaluate the effect of discarge of rain water to recipients and ground water
• reflect on and explain the chosen solutions
• reflect on the group’s cooperation focusing on the interaction between international students and Danish students

A road must be able to last for many years of traffic. In recent times, roads have also begun to be used for temporary storage and infiltration of rainwater so that the worst effects of cloudburst are averted. The course ensures competences within the construction and dimensioning of a traditional road pavement, with additional knowledge of permeable pavements.
Road construction
• Materials: Gravel (bottom protection grid, bearing layer and as bearing layer), asphalt, concrete
• The road structure – calculating (MMOPP)
• Basis layer. Proctor Test, Marshall Test (on an asphalt lab)
• Operation and Maintenance, Pavement Management: Monitoring, laping, change of wear, snow removal, salting.
• Supply: AAB, SAB, drawings, supplementary studies
• Execution: Methods, machinery, building materials, soil work

Water
• Drainage of roads
• Quality of rainwater from roads and other surfaces, the effect of ‘winter control’
• Methods for local water treatment
• The effect of drainage of rainwater to recipients and groundwater.

Permeable pavements
• Why implement permeable pavements: Flat surfaces (without slope), rainfall delay, rainwater drainage.
• Materials: Permeable asphalt, cobblestone, permeable concrete blocks, permeable bearing layer, permeable subgrade
• Structure: infiltration of all water, partial infiltration, no drainage
• Design and calculating: Selection of solution, pollution and drinking water interests, determine volume of water that can be infiltratet/ delayed
• Operation and maintenance
• Execution
