Abstract
Road maintenance operations involve the preservation of the optimal functionality of the pavement. Sometimes the rehabilitation of the pavement layout does not have long lasting effects due to a lack of compliance with the constraints imposed by the technical specifications for the design of materials. The purpose of this paper is to present an efficient BIM tool to help in road maintenance operations through the management of data arising from laboratory testing of road pavement bituminous materials required for the quality control of mixtures. The database associated to the BIM model is a collection of three years of data derived from laboratory investigation on bituminous mixtures’ samples adopted for the maintenance of four main roads located in southern Italy. An algorithm that interacts with the three-dimensional road model has been implemented in order to give road administrations an easy-to-read alert signal for the road pavement structure of the road network that may present the most critical conditions due to poor mechanical and physical features.
Highlights
The inclusion of Bitumen content (BC) in the range 4.5%–6.1% was verified through the algorithm reported in Figure 14. e average bitumen content of the mixture was confronted with the lower (1) and upper (2) limit imposed by the technical specifications, and the results were expressed by Boolean variables that were used as an input to an “if” block (3)
The methodology implemented here allowed for the creation of an integrated RevitR model that stores and analyzes data produced by the quality controls of the bituminous materials after laying and compaction
E applied methodology resulted in a dynamic model that updates its information package and modifies the output of the analysis every time the data worksheet is integrated with new test results. e execution of the algorithm directly interacts with the appearance of the road network model, giving the user, namely, the road administrator, an easy-to-read alert signal for a specific element of the road pavement structure
Summary
Pavement, the application of BIM technology in the road design is not limited to the route design but can reflect the pavement design and management information. Once the current state of the elements of the road network under analysis was correctly modelled and parameterized, a number of shared parameters to be associated with the road pavement materials were created to match the information contained in the database using DynamoR. DynamoR is a visual programming tool (VPL) that works with RevitR. DynamoR successfully integrates BIM with the data management within the environment of a graphical algorithm editor. Users can create geometries and manipulate models in RevitR or within DynamoR by coupling code blocks, which are programmed to execute a task assigned to them. E nodes consist of a script, which are assigned a task. It can involve a very simple operation such as storing a number in a list, creating complex geometry, or manipulating imported data. The majority of nodes are composed of five parts: (1) name of the node; (2)
