OROBIO, Armando  e  OROBIO, Juan Carlos. Plain-concrete strip road pavements: 3D finite element analysis. Dyna rev.fac.nac.minas [online]. 2016, vol.83, n.199, pp.9-18. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v83n199.55350.

The construction of strip road pavements has increased in the recent days in Colombia. This type of pavements is being used for rural low-traffic volume roads, the type of strip road pavement used nationwide is made of reinforced-concrete, the construction in based mainly on the particular construction specification 500-1P that has only one configuration of the pavement, which raises doubts on its application for different projects. In this research, a finite element analysis was performed to study the response of concrete strip road under different load configurations and soil support. The design of plain-concrete strip roads pavements was evaluated for the maximum loads of C3 trucks and 20 years of design period. The results showed that although this type of strip road may meet fatigue criteria, the erosion criteria is uncertain due to lack of data to calibrate an erosion model to perform this evaluation.
