How SmartPave accessories can be auspiciously activated for the allocation and the analysis of altered bitumen types according to the American standards
1. SmartPave

The SmartPave accessory is a activating microburst rheometer (DSR) and is based on the MCR technology of the MCR rheometer alternation by Anton Paar with the accurate EC drive. The patented Peltier altitude corpuscle in aggregate with the alive Peltier awning enables a absolutely dry temperature ascendancy of the sample. There is a ample best of accepted rheological tests accessible in the accessible software as able-bodied as abnormally tailored analysis templates for the characterisation of bitumen. These templates acquiesce alike unexperienced users to conduct absolute abstracts according to AASHTO T315 and ASTM D7175 by agency of a footfall by-step guidance.
2. Classification of Altered Bitumen Types

Bitumen is about classified into two altered types:
With attention to the crumbling condition, bitumen is categorised into three crumbling stages by applying three altered tests:
3. Analysis Types
The rheometer software provides analysis templates according to AASHTO T315 for the accepted analysis methods such as the allocation as able-bodied as the agnate analysis of the grading. Within these tests, |G*| and sin δ are determined, area sin δ equals the sine of the appearance bend about-face δ.
Grading of original, RTFO- and PAV-aged binder
The allocation analysis helps to actuate the aerial temperature allocation of the advised bitumen according to the blueprint of AASHTO M320 and M322 which lies amid 4 °C and 88 °C.
For this purpose, the bitumen’s visco-elastic backdrop are bent in an oscillatory analysis with a plate/plate-measurement system. The activated abundance is absolute of the case and stays connected during the test. As adjoin to that, the anamorphosis as able-bodied as the bowl bore and the gap are adapted to the crumbling action of the bitumen (Table 1).
These are single-point measurements, of which the aftermost 10 abstracts credibility are averaged in adjustment to accomplish one abstracts point. The arrangement |G*| / sinδ [kPa] is affected for the aboriginal and the RTFO-bitumen. For the PAV-bitumen, however, these ethics are multiplied: |G*| x sinδ [MPa]
Table 1: Blueprint according to AASHTO M320/322
The temperature is automatically added from a authentic starting temperature with an accession of 6 °C for the altitude of the aboriginal adhesive and the RTFO-aged bitumen. As the temperature increases, the appraisal amount decreases simultaneously. As adjoin to that, the temperature is automatically decreased by 3 °C-steps during the altitude of the PAV-aged binder. In this case, the evaluated amount increases with abbreviating temperature.
The altitude is aborted already the appraisal belief of the aboriginal or RTFO-aged adhesive avalanche beneath or the appraisal belief of the PAV-aged adhesive transgresses the authentic casual belief according to AASHTO M320/322 (Table 1). The after-effects accommodate advice about the attrition adjoin a abiding anamorphosis of the binder.
Figure 1 representatively displays a altitude of an aboriginal binder. 64 °C was called as a starting temperature for the displayed altitude in Figure 1. The aboriginal altitude takes abode at this temperature (upper, blooming abstracts set). The appraisal of |G*| / sinδ leads to ethics about 1.5 kPa. Thus, the bitumen passes the criteria. The temperature is again aloft by 6 °C, captivated for ten account and the aloft declared altitude again (lower, dejected abstracts set). This time the amount lies beneath the casual absolute of 1.0 kPa.
The afterward rules administer for the activated aboriginal binder:
Figure 1: Altitude of a accepted alley architecture bitumen with a abort temperature of 70 °C
After the altitude is aborted, the rheometer software automatically creates a agreement which depicts an overview of the capital results.
Verification of the original, RTFO- and PAV-aged binder
The analysis complies with the guidelines of the allocation according to AASHTO T315 and ASTM D7175. However, this analysis is conducted at a distinct temperature. The aftermost temperature of the allocation is acclimated for the verification. The two generated after-effects are again compared.
