The Hamburg wheel tracking test (HWTT) is widely used to evaluate the performance of asphalt mixtures. According to HWTT specifications, the stripping inflection point (SIP) and the rut depth at a certain number of load cycles are two common indicators for evaluating the moisture susceptibility and rutting resistance of asphalt mixtures, respectively. Although these indicators have been used extensively by several transportation institutions, the reliability and stability in evaluating asphalt mixture behaviors of these indicators have been questioned. To more effectively evaluate the performance of asphalt mixture in the HWTT, this study introduces a novel method of analysis for the HWTT and novel indicators of rutting resistance and moisture susceptibility. The proposed method and indicators were employed to analyze the HWTT results of 14 field core specimens, and the proposed indicators were compared with conventional HWTT indicators to assess their capability of distinction between asphalt mixtures with different performance behaviors in the HWTT. The results indicate that the conventional HWTT indicators cannot effectively evaluate the asphalt mixtures with different performance in the HWTT. By contrast, the proposed analytic method and indicators have significant advantages to effectively evaluate and distinguish the rutting resistance and moisture susceptibility of asphalt mixtures.

Hamburg Wheel Tracking

The Hamburg wheel-tracking test (HWTT) is commonly used to evaluate the rutting resistance and moisture susceptibility of asphalt mixtures. Over the years, different test parameters have been proposed, including the traditional ones specified in AASHTO T 324 and several alternatives developed by asphalt researchers. This study was undertaken to refine the HWTT method toward enhancing its implementation as part of balanced mix design specifications for asphalt mixtures. A HWTT database was developed including test results of over 70 mixtures with a wide range of mixture components and production parameters. Data analyses were conducted to examine the relationships among various HWTT parameters, determine their correlations to field performance data, and estimate the within-laboratory repeatability of the test results. Two alternative rutting parameters, rutting resistance index ( RRI) and corrected rut depth ( CRD), were found to be advantageous over the traditional parameters of total rut depth ( TRD) and creep slope ( CS). RRI allows for direct comparison of results with different termination points, and CRD isolates the rut depth resulting from permanent deformation from that caused by stripping. Among all the rutting parameters, RRI had the best correlation to field rut depth, followed by CS, CRD, and TRD. Receiver operating characteristic analysis was conducted to determine the correspondence between HWTT results and pavement field performance related to moisture susceptibility. The analysis identified 9,000 passes as the best criterion for stripping inflection point and 2,000 passes for the alternative moisture susceptibility parameter, stripping number. Finally, the within-laboratory repeatability of HWTT rut depth measurements was determined.

According to the porous asphalt concrete’s big void structure as well as high temperature and rainy application environment, the author point out that using the conventional evaluation index such as high temperature stability and water stability to evaluate the PAC’s performance seem single, and then put up with estimating the PAC’s pavement performance by means of Hamburg Wheel Tracking under the water-high temperature’s comprehensive action. Studied on the PAC with the same raw materials and different gradations, and compared with the experimental results of AC-13 modified asphalt mixture and SMA-13, the results shows that, Hamburg Wheel Tracking test not only considered the water-high temperature’s comprehensive action on mixture, but also considered the mixture’s performance decay under long-term loading. Hamburg Wheel Tracking test can evaluate the PAC’s performance more practically, the PAC which materials and graduations reasonably designed have good performance, and its Hamburg Wheel Tracking final deformation is only 3.89mm, it can satisfy the demand from the high temperature and rainy environment. As well, the test results also comes to the conclusions that under the same materials and the same air voids, the PAC with coarse framework structure own better water stability and water-high temperature stability.

Cold bituminous mix (CBM), which is a mixture of bitumen emulsion and aggregate that is mixed together at ambient temperature, has several advantages like energy savings, easiness in preparation, environmental benefits, and high production at low investment. But there are certain limitations of CBMs like inferior mechanical properties, high air voids, weak early life strength, long curing time and poor coating that hinder its extensive usage. The possibility of improving mechanical performance of CBMs by the addition of coir fibre is attempted in this study. The objectives of the study are to assess the improvement in performance of CBM due to addition of coir fibre and to identify the optimum length and optimum content of coir fibre for CBMs. Three coir fibre contents and three coir fibre lengths were used in this study. Performance evaluation of CBM modified with coir fibre was done through Retained Marshall Stability (RMS) test and Hamburg wheel tracking test. Coir fibre was added to the aggregates and mixed before the addition of pre-wetting water and emulsion, to achieve uniform distribution and to avoid balling of coir fibres. When coir fibre was added to the mix, Marshall Stability increased up to a certain level of coir fibre content depending on fibre length. Highest Marshall Stability value was obtained at 0.2% content (by weight of total mix) of coir fibre of 15 mm length. Resistance to moisture damage was assessed by RMS test. It was observed that the addition of coir fibre improved the RMS value. From the Hamburg wheel tracking test, it was observed that the addition of coir fibre improved rut resistance. For all fibre lengths, CBM with 0.2 % coir content showed the highest rut resistance, with 10 mm fibre length showed the best performance. Hence, coir fibre is recommended as a feasible additive for mechanical performance improvement of CBMs.

This paper investigates the applicability of the Hamburg wheel-tracking test (HWTT) for asphalt mixture quality acceptance using laboratory-compacted specimens and field-compacted specimens. Density distribution functions for rut depths, stripping inflection points, and rutting resistance index (RRI) values used in the HWTT were obtained for mixtures with different nominal maximum aggregate size (NMAS) values and binder performance grades. Clear distinctions among the rut depth distributions for the high-temperature performance grade mixtures were observed in the laboratory-compacted specimens. The RRI values for both the laboratory and field-compacted specimens increased with an increase in the binder performance grade. In addition, the RRI values showed clear differences for different binder grades among the mixtures with the same NMAS. The range of the RRI distributions for the laboratory-compacted specimens was narrower than that of the field-compacted specimens. The stripping inflection points of the field-compacted specimens increased as the binder grade was increased, indicating better moisture damage resistance for stiffer mixtures. HWTT results were significantly influenced by the air voids content of specimens. The relationship between air voids content and RRI can be used for understanding the critical effect of in-place density in pavement performance. The laboratory-compacted and field-compacted specimens offer advantages and disadvantages. The laboratory-compacted specimens were much easier to fabricate to standard dimensions, and the field-compacted specimens present inherent variability in relation to air voids content, diameter, and thickness.
