Performance Evaluation of High Modulus Asphalt Mixture

Performance Evaluation of High Modulus Asphalt Mixture


Fatigue-healing performance evaluation of asphalt mixture

The stiffness modulus healing indices of the two asphalt mixtures are higher than their fatigue-life healing indices, except for the SBS-modified asphalt mixture with less damage. 3. When the stiffness modulus of the asphalt mixture drops below 20% of the initial value after the fatigue test, the fatigue-healing capability reduces sharply and

Rheology and performance evaluation of Polyoctenamer as

The performances for the dynamic modulus, flow number and indirect tensile strength ratio test of the laboratory-produced mixtures with and without PO were not statistically different. Accordingly, the mixes' master curves showed no difference. Overall, the addition of PO does not negatively affect the performance of asphalt rubber mixes.

compacted asphalt plant mixtures. Based on the research findings, both stiffness and strength are needed to predict mixture performance. Although mixture response obtained at lower and higher testing temperature deviates, at this point the lower testing temperature is recommended mainly to minimize the testing variation. Both

Evaluation of Moisture Damage Within Asphalt Concrete Mixes

Evaluation of Moisture Damage within Asphalt Concrete Mixes. (August 2003) Brij D. Shah, B.E., Gujarat University Moisture damage was monitered as a change in dynamic modulus with load cycles. The analysis demonstrates the need to consider mixture compliance as test methods to predict the performance of asphalt mix would always add to

Laboratory performance characteristics of high modulus

As the most important parameter to define high modulus asphalt mixture is the dynamic modulus at 15 °C and 10 Hz, dynamic modulus test was used to determine the optimum asphalt content of HMAC. The performance testing results for moisture stability, rutting resistance and low-temperature cracking resistance were used to verify the determined

Research on Evaluation Index of Water Stability for

The high temperature stability, anti-cracking performance and water stability of TOR asphalt rubber mixture were studied and the influence of dry and wet molding process on road performance of TOR asphalt rubber mixture was compared. The results show that both the dynamic stability and the low-temperature cracking performance of wet forming

Evaluation of Bituminous Mix Characteristics Prepared with

The stiffer or hard binder shall provide solution for improving the performance. This article aims in evaluating the performance characteristics of high modulus asphalt concrete (HMAC) mixture from the laboratory-developed high modulus asphalt binder (HMAB). The HMAC mixes prepared with HMAB require a penetration value of 10/20 or 15/25 at 25 °C.

Evaluation of Crumb Rubber in Hot Mix Asphalt - Rutgers CAIT

The performance tests concluded that the AR-HMA mix performed as well as or better than the PG76-22 for every test conducted. For example, the dynamic modulus test results showed that the AR-HMA had similar stiffnesses to the PG76-22 at the high test temperatures, however, the AR-HMA had a much less stiffness at the low test temperature.
