Characterization of new asphalt concrete for reduced transport emissions

Modern asphalt mixes may be designed with improved environmental attributes such as lower rolling resistance and lower noise emission. The resulting societal benefits are reduced CO2 emissions and better fuel consumption. This project involves advanced testing and data interpretation of several versions of such new mixes. The aim is to investigate and compare their mechanical properties as a first step towards implementation in the live transportation network. Experimental work will be performed in the Vejdirektoratet (Roskilde), under the supervision of Matteo Pettinari.

Durability evaluation of new asphalt concrete for reduced transport emissions

Three new asphalt concrete mixes were designed to offer reduced transport emissions. Slabs fabricated from these mixes, with 14 different variants, were loaded by circular load simulator at VTI - the Swedish National Road and Transport Research Institute (Linköping). The aim of the work is to analyse the available experimental data to arrive at practical implementation conclusions. Experimental results include diverse information on the evolution of properties and behaviour (w.r.t. number of passes) such as texture and slab rutting. This work will be carried out in close collaboration with Matteo Pettinari from the Vejdirektoratet (Roskilde).

Full scale evaluation of new asphalt pavement for reduced transport emissions

A full scale asphalt pavement test section was constructed by NCC in Kalvehave. This test section included three different surface mixes: two new mixes designed for reduced transport emissions and one standard mix as reference. Structural surveys were performed before and immediately after paving. Also, functional properties were collected periodically, including: surface texture, skid resistance, rolling resistance, and noise. The aim of the work is to analyse the available experimental data towards adoption of the new mixes. This work will be carried out in close collaboration with Matteo Pettinari from the Vejdirektoratet (Roskilde).

Unbound Granular Material Characterization under Cyclic Triaxial Conditions

Pavement structures include layers of compacted unbound granular materials (UGMs). Most often, the resilient modulus of UGMs, as well as their overall adequacy to serve as pavement layers, are a priori estimated based on correlations with classification parameters or aggregate index tests. With such empirical approach there is a risk of conservatism, i.e., that of excluding acceptable materials. In this connection an M.Sc. investigation is proposed, focused on a case study and dealing with direct measurement of UGM properties. SWECO has consented to support the case study along with Geo in Lyngby that owns a suitable cyclic triaxial test setup. The case study deals with a Danish highway project wherein usage of available UGM was disallowed, and more expensive material was purchased and employed instead. With access to both the discarded material and the UGM ultimately utilized, the overall incentive of the investigation is to test both UGMs under resilient modulus protocol (AASHTO T 307), compare the results, and assess whether the discarded material should have been used.

The investigation will include Svend Pilgaard Larsen from engineering consultancy Geo as co-supervisor.
