RPD (Road Pavement Design) \u2013 Software for verifying road flexible and semi-rigid pavements.<\/p>\n

RPD is a software that implements automatic procedures for pavements verification calculations.<\/p>\n

With RPD you can perform the verification procedures by empirical methods (as proposed by AASHTO in the document GUIDE FOR DESIGN OF PAVEMENT STRUCTURES) or by rational methods.<\/p>\n

Among the rational methods, the highest deflection is implemented (Ivanov) and Westergaard\u2019s, designed to calculate deflections on multi-layer pavements.<\/p>\n

The method is based on considerations resulting from experimental tests.<\/p>\n

The general principle of the method is to measure the adequacy of road pavement in terms of the number of vehicles (standard axes from 82 kN) that a road pavement can withstand, maintaining the desired functionality, for a certain number of years (set as a project data and equal, in most cases, to the useful life of the road).<\/p>\n

WESTERGAARD<\/strong><\/p>\n

It is based on the Lagrange equation solution for thin sheets.<\/p>\n

Generally, a method is a tool for calculating the maximum deflection subjected to a thin layer sheet (to which road pavement is approximated).<\/p>\n

The verification criterion (project) is similar to the one on which the maximum deflection method is based.<\/p>\n

IVANON<\/strong><\/p>\n

The method of maximum deflection (Ivanon) is based on the elastic problem setting in the lands given by Boussinesq.<\/p>\n

The criterion is based on limiting the maximum deflection occurring at the end of the useful life of a road pavement.<\/p>\n

Features of RPD: Parametric Calculation \u2013 immediate display of results \u2013 automatic calculation of project traffic, maximum bearable traffic, pavement\u2019s Structural Number, layer structure coefficients, coefficients of drainage of layers.<\/p>\n

RPD has an intuitive interface that simplifies its use, and each parameter is described and verified in detail.<\/p>\n

RPD provides a detailed complete calculation relationship with theoretical references.<\/p>\n

RPD helps calculate, verify and optimise road pavements.<\/p>\n
