“…Short-cut basalt fibers and short-cut polymer fibers are the most commonly used road fibers. Compared with the latter, basalt fibers have better high temperature stability and mechanical properties [ 6 , 7 ]. Many researchers have studied the viscoelastic behavior of basalt fiber asphalt mixtures, and they have used more dynamic modulus and phase angle to analyze its viscoelastic behavior, and seldom evaluate their viscoelastic properties comprehensively [ 8 , 9 ].…”

In order to analyze the differences between the master curves of relaxation modulus E(t) and creep compliance J(t) obtained from discrete and continuous spectrum models, and to comprehensively evaluate the effect of basalt fiber content on the viscoelastic behavior of asphalt mixtures, complex modulus tests were conducted for asphalt mixtures with fiber content of 0%, 0.1%, 0.2% and 0.3%, respectively. Consequently, the master curves of Viscoelastic Parameters of asphalt mixtures were constructed according to the generalized Sigmoidal model(GSM) and the approximate Kramers-Kronig (K-K) relationship. Then, transformation of master curves using discrete and continuous spectrum models to obtain the models of E(t) and J(t) containing all viscoelastic information. Also, the accuracy of the models of E(t) and J(t) was evaluated. The results show that the addition of basalt fibers improves the strength, stress relaxation and deformation resistance of asphalt mixtures. It is worth noting that basalt fibers achieve the improvement of asphalt mixtures by changing their internal structure. Considering the different viscoelastic master curves at four dosages, the optimum fiber dosage was 0.2%. In addition, both discrete and continuous model conversion methods can obtain high accuracy conversion results.

“…In this paper, the uniform temperature drop model of the CRC layer is established with the continuously reinforced concrete plus asphalt overlay composite pavement (CRC+AC) as the research object. The article considers the drying shrinkage of concrete materials and the restraint effect of the grassroots level and derives the analytical solution formula of crack control index [3]. At the same time, we use ABAQUS finite element software to verify the validity of the formula.…”

The thrust of basalt fibre (BFRP) tendons will result in narrower transverse crack spacing, decreased load transfer capacity of transverse cracks and voids at the bottom of the slab, which will lead to thrust failure. The thesis uses the finite element analysis method to analyse the material characteristics of BFRP tendons. At the same time, the article determines the critical load position corresponding to the tensile stress of concrete and BFRP tendons, and analyses the influence of voids, crack spacing and other factors on the load stress of concrete and BFRP tendons. The study results found that continuously reinforced concrete and asphalt overlay composite design can reduce cracks.
