Testplatser för 74 ton tunga fordon :två instrumenterade tunna vägkonstruktioner

Test sections for 74 tonnes vehicles :two instrumented thin pavement structures

This VTI note describes briefly the construction and instrumentation of two new test road structures that have been built during the autumn 2017 on Lv373 and Lv515 respectively in Norrbotten County in northern Sweden. One structure is placed on Lv373 east of the village Långträsk while the other structure is on Lv515 south if the intersection with Lv373. The distance between the two locations is about 10 km. Both structures are thin pavement structures. The main objective of the two new test sites is to estimate the impact that the new 74 tonnes vehicles have on the Swedish road network. This will be done through direct measurements of the pavement response from the road sensors. The sensors consist of horizontal strain sensors in both longitudinal and transversal direction at the bottom of the asphalt layer as well as vertical strain sensors over every layer down to 1.2 m depth. Soil pressure cells are further installed at two depths. The local ambient climate is monitored as well. A frost and a moisture rod were therefore installed. Further are temperature sensors installed in the asphalt concrete. Two weather stations are located within 20 km distances from the test structures. The first response measurements are planned in the late summer or early autumn 2018.
