The negative factors of the colored asphalt mixture extremely correlate to its high-temperature behavior. With the Grey Relation Analysis, this paper makes a thorough analysis of the affective factors on the high-temperature behavior of the colored asphalt mixture, the result of which shows that the affective factors can be classified as the softening point of colored asphalt and the aggregate ratio of mixture. The research findings will provide a beneficial reference for the design of colored asphalt mixture.

Road construction consumes great amounts of high-grade natural resources. Using low-grade natural rocks or some solid wastes as substitute materials is a hot topic. Considering this, the feasibility of using low-grade granite aggregate, solid waste-based filler (desulphurization gypsum residues, DGR) and binder (waste tire rubber modified asphalt, RMA) simultaneously in asphalt mixtures has been fully investigated in this research. The commonly used base asphalt and limestone powder (LP) filler were control groups. Material characteristics of raw materials mainly including micro-morphology, functional group, mineral phase, chemical composition and thermal stability were first evaluated in order to recognize them. Four asphalt mixtures (two asphalt binder and two filler) were then designed by standard Superpave method. Finally, a detailed investigation into the pavement performance of asphalt mixtures was carried out. The moisture damage resistance and low-temperature crack resistance were detected by the changing rules of stability, strength and fracture energy, and the high-temperature stability and fatigue performance were determined by wheel tracking test and indirect tensile (IDT) fatigue test, respectively. Results suggested that RMA and DGR both showed positive effects on the low-temperature crack resistance and fatigue property of the granite asphalt mixture. DGR also strengthened moisture stability. The contribution of RMA on high-temperature deformation resistance of the granite asphalt mixture was compelling. It can offset the insufficiency in high-temperature stability made by DGR. A conclusion can be made that asphalt mixture prepared with granite, DGR and RMA possesses satisfactory pavement performances.

Crack resistance is an important indicator to evaluate asphalt mixture performance, so the critical fracture criterion of asphalt mixture was deeply studied based on semi-circular bending test under different temperature. The results show that Semi-circle bending test is suitable to evaluate the crack resistance of asphalt mixture; fracture toughness Jc is a more reasonable indicator of the fracture criterion for asphalt mixture than Kc; The fracture toughness calculation model of single specimen built in this paper can simplify the semi-circular bending test operation, and can reduce the number of test specimens.

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.

There are many parameters that could affect the properties of asphalt mixtures, such as the fiber additive, gradation type, nominal maximum aggregate size (NMAS), and asphalt. To evaluate the influence of these factors on the crack resistance of asphalt mixture, 10 different types of asphalt mixtures were prepared. The indirect tensile asphalt cracking test (IDEAL-CT) and semi-circle bending test (SCB) were adopted to test the anti-cracking ability of the test samples. The parameters of these two test results were also used to conduct the correlation analysis to find the correlation between different parameters, and scanning electron microscope (SEM) test was also used to analyze the micro cracks of asphalt mixture. The results showed that basalt fiber could further enhance the anti-cracking ability of asphalt mixture. Stone matrix asphalt (SMA) showed better anti-cracking performance than Superpave (SUP) asphalt mixtures. The increase in the nominal maximum aggregate size could decrease the anti-cracking ability of asphalt mixtures. Styrene-Butadiene-Styrene (SBS) modified asphalt could better reinforce the anti-cracking ability than pure asphalt. The CTindex of IDEAL-CT test and Flexibility index (FI) value of SCB test results showed better correlation. This paper has certain significance in guiding the design of asphalt mixtures having good crack resistance.
