The influence and influence mechanism of three different kinds of fibers, xylon fiber, polyester fiber and basalt mineral fiber, on the pavement performance of Stone Matrix Asphalt (SMA) are investigated for optimizing the pavement performance of SMA in this paper, by comparative analysis of high temperature performance, water stability and low temperature performance of SMA with the three different types of fibers. The results suggest that there are large differences in the performance of SMA with the three kinds of fibers above mentioned, because of the different dispersibility and adsorption capacity of each fiber, and SMA with basalt mineral fiber has the best behavior in pavement performance.

Stone Matrix

There are a number of factors affecting on the high temperature and water stability of Stone Matrix Asphalt (SMA). However, under a concrete condition of traffic, climate and construction, together with reliable raw materials, the proportion of various raw materials are the main factors. SMA-16 is taken as an example, by using the Rutting test, Residential stability test and Freezing–thaw cycling test for analysing the impact of the modified asphalt, fiber and mineral filler proportion on SMA. The result shows that these three factors significantly impacted on the high temperature and water stability of SMA with the optimal values of 6.0-6.2%, 0.31% and 10-11%, respectively.

The performance of asphalt concrete mixed with 3 types of fine aggregate respectively (i.e. natural sand, limestone, basalt) are compared. The results of Marshall test and rutting test show that the high temperature performance of asphalt mixture mixed with basalt is the best, that of asphalt mixture mixed with natural sand is the worst, and that of asphalt mixture mixed with limestone is between the above two. The result of immersion Marshall test show that the water stability of asphalt mixture mixed with basalt and that of asphalt mixture mixed with limestone are similar, but better than that of asphalt mixture mixed with natural sand. Therefore, it indicates that the machine-made aggregate (of basalt or limestone) have better pavement performance and environment benefit than the natural sand.

To make nano calcium carbonate as the modifier, firstly the best proportion of nano calcium carbonate is determined as 6% by comparing the influences of different proportions of nano calcium carbonate to the indexes of asphalt. Then the influence of mixing with nano calcium carbonate to the performance of asphalt concrete AC-13 has been studied. Tests show that, the mixing of 6% nano calcium carbonate has improved the dynamic stability of asphalt concrete AC-13 from 991 times/mm to 1269 times/mm; the residual stability from 0.87 to 0.94. This indicates that after mixing with nano calcium carbonate, both the high temperature performance and water stability of asphalt concrete have been improved.

In order to improve the pavement performance of reclaimed asphalt mixture, using Marshall test, rutting test, splitting test and long-term aging test, taking stability, dynamic stability, fatigue strength, stiffness modulus, and freeze-thaw splitting tension strength as the target, the influence law of old asphalt mixture content and regenerant content on pavement performance of reclaimed asphalt mixture is systematically studied. The results show that: the proportion of old asphalt mixture has no influence on high temperature performance of reclaimed asphalt mixture. With the proportion of old mixture increases, the optimum asphalt-aggregate ratio, low temperature performance, water stability, and anti-aging property of reclaimed asphalt mixture decrease. Addition of regenerant improves the low temperature performance of reclaimed asphalt mixture, and reduces the strength and high temperature stability of reclaimed asphalt mixture. Research results have great guiding significance for old asphalt mixture content selection, regenerant content selection and improving pavement performance of reclaimed asphalt mixture.

To research the grading applicability of Lucobit modifier and make it adapt to China's basic national conditions very well, the gradations of SUP-20 was selected to research mix design and pavement performance in the text. First, the mix design of SUP-20 without Lucobit is researched. Then the performance of SUP-20 is verified including the high temperature, low temperature and water stability performance of common asphalt mixture. At last the performance comparison between SUP-20 asphalt mixture with 7% Lucobit and without is carried out. Results show that the performance of SUP-20 asphalt mixture with 7% Lucobit and without can all meet the requirement. Compared with the performance of SUP-20 asphalt mixture without Lucobit, the low temperature and water stability performance with Lucobit have a little improvement and the high temperature performance improves a lot. So Lucobit modifier can greatly improve the high temperature performance of SUP-20 asphalt mixture.

It was based on laboratory test, in order to study on the high temperature stability, water stability and low-temperature crack resistance of AC-16 reclaiming asphalt mixture with different proportion of old material, this test takes into account 9 kinds of these asphalt mixture. The results show, with the old material blending ratio increased, the high temperature stability of asphalt mixture changed for the better, water stability and low-temperature crack resistance deteriorated. The pavement performance meet the requirements of secondary road or less, when old material content is within 70%. The research results provide reference for the application of reclaiming asphalt mixture.
