Abstract

In this article, we introduce DACE® software as an alternative of computational calculation for the design of unpaved roads, using the semi-empirical methods of Giroud, Han and Pokharel, which were published in 2004 and 2015. As a conclusion, the use of the Hypertext Preprocessor (Php) programming language, applied in order to develop DACE®, allows it to be cross-platform software since it is a web application, therefore, it works in all operating systems. Furthermore, the results obtained using DACE®, were satisfactorily validated with the exercise proposed by Han and Pokharel in 2015, therefore, it allows to determine the thicknesses of unreinforced unpaved roads (without geosynthetic), with geotextile (woven geotextile), biaxial geogrid and geocell. Lastly, DACE® is a software that will help estimate the thickness of an unreinforced unpaved road (without geosynthetic), with geotextile (woven geotextile), biaxial geogrid and geocell, whenever the subgrades have a California Bearing Ratio of the sub-grade soil (CBRs) value equal to or less than 3% and a reliability value of 50%. In addition, itis possible to apply similar thicknesses in-situ of the specimens of the CBR and modified proctor tests.
