RESULTS OF TEST SITE EXPERIMENTATION WITH FIVE 35/50 MULTIGRADE BITUMENS FROM THE FRENCH MARKET ON A HEAVY FRENCH TRAFFIC ROUTE BETWEEN 1999 AND 2003
In 1999, a partnership agreement was signed between the French road authorities and the Bitumen producers with the aim of evaluating a new family of bituminous binders known by the name of multigrade bitumens, and their performances in terms of rutting resistance, cold cracking resistance and durability on heavy traffic routes. To this end, a heavy traffic route (the RN 70) was selected in Saone-et-Loire (near Montceau-les-Mines in Bourgogne) for the purposes of creating, in September 1999, a testing site 3 km in length using the five multigrade bitumens on the market. The comparison was made with a 6th binder, a traditional penetration grade 35/50 binder, which was used as a reference. Rheological analyses were performed, particularly the complex moduli, with DSR type, viscoelastometer type and BBR type rheometers on fresh binders, on binders aged by RTFOT or by RFTOT + PAV, on binders extracted from fresh asphalts straight from the plant and on binder core samples taken after one year on the road. Observations from visual inspections, geometric roughness and cross sections were also made over a usage period of three and a half years. The results after 3.5 years in service demonstrate that the multigrade binders have good anti-rutting and cold cracking resistance properties by comparison with the bitumen taken as a reference, and relatively little difference between the five multigrade bitumens themselves. This paper describes the results obtained for the various experiment tests that potentially relate to performance. For the covering abstract see ITRD E121480.
