Abstract

This internship was part of a programme that has been going on since 2012, and is called ‘NL-LAB’, standing for National Living Lab. This program deals with a very large database from asphalt tests and measurements, both in labs and in the field, provided by the contractors that cooperate with RWS. The questions set at the initiation of the project were:
1. How (well) do the functional characteristics relate to field performance?
2. Is testing on laboratory mixed and compacted the correct choice?
3. Are the current tests able to distinguish “good” from “bad” mixtures?
4. How accurate and reliable can the prediction of a mixture’s performance be, based on its volumetric properties?

Relating to this program, this technical report tries to answer the following: 1) To obtain a predictive formula (via a Regression analysis) that outputs the asphalt’s performance regarding Rutting and Water Sensitivity, and 2) Compare the field to the lab properties and locate inconsistencies or trends in their relation.
