UTPLPave: an online software package for pavement structural design in roads using AASHTO-1993 methodology

The pavement structural design of one road is one of the variables that can most influence the cost of construction and maintenance of the pavement. For the design of pavements, one of the most used methodologies in Latin America is the proposal for AASHTO in 1993. Figures, tables, and equations are used in this methodology, which could confuse an inexperienced designer. Therefore, several computer programs have been developed using this methodology, however, they only show the results and not the process to get to these ones. In this context, this study aims to develop software for designing flexible pavements, rigid pavements and overlayer on the flexible pavement, which allows users to observe the procedure carried out by the program. Those individuals programs make up the computational package called UTPLPave, which is a free online version and it was developed using JavaScript libraries in HTML5 and BootStrap. This program can be used as a complementary tool for university education or for updating of knowledge of pavement designers.
