“…Both the friction between the concrete and the base layer and the bond between the concrete and the BFRP reinforcement impose a constraint on the concrete horizontal displacement, and thus friction and bond must be introduced into the analytical model to predict crack spacing and crack width [17]. It was assumed that the friction-slip relationship between the base and the concrete as well as bond-slip relationship between the BFRP reinforcement and the concrete are linear, as shown in Equations ( 1) and (2).…”

Continuously reinforced concrete pavement (CRCP) is a pavement structure with a high performance and long service life. However, the corrosion of the longitudinal steel can result in a poor bond relationship between the steel and the concrete, affecting the load transfer efficiency between the adjacent panels and being responsible for the development of CRCP distresses. Basalt fiber-reinforced polymer (BFRP) is corrosion-resistant and has the potential to be used in CRCP. In this paper, the layout of a CRCP test section with BFRP bars constructed on G330 National Road in Zhejiang Province, China, is presented. An analytical model is proposed to predict the crack behavior of CRCP with BFRP reinforcement, with the predicted results are compared to field-measured ones. A sensitivity analysis of the BFRP design parameters on the crack spacing and crack width is conducted as well. The results show that the mean values for field-measured crack spacing and crack width are 4.85 m and 1.30 mm, respectively, which are higher than the results for traditional CRCP with steel due to the lower elastic modulus of BFRP. The analytical predictions agree reasonably well with the crack survey results. The higher the elastic modulus of BFRP, the reinforcement content (with both BFRP spacing and diameter related), and the bond stiffness coefficient between the BFRP and concrete, the less the crack spacing and crack width will be. Given the same or similar reinforcement content, a lower diameter with a smaller spacing is recommended because of its contribution to a smaller crack spacing and width.

“…Although a finite difference method using a bilinear function proposed by Xin, Zollinger, and James (1992) and Rasmussen and Rozycki (2001) is a reasonable approach, the methods were too complicated and required many assumptions for the analysis. Therefore, this paper proposes a bilinear function based on the energy method to explain the relationship between the friction resistance force and displacement through field measurements.…”

This paper presents the results of an analysis of the interlayer friction characteristics between a concrete slab and various types of subbases, which are commonly used in concrete pavement construction. The interlayer friction characteristics were examined by conducting push-off tests on concrete slabs placed on top of lean concrete, crushed stone, or asphalt subbase, with and without separation membranes, under a range of saturated conditions. Throughout the tests, the friction resistance force and horizontal displacement, along with different types of subbases, were measured during the first application of a load, steady conditions, and saturated conditions. The measured interlayer friction resistance force and horizontal displacement after applying the first load showed results similar to other studies. To incorporate the test results into an analysis, a simple method was developed to estimate the maximum friction resistance force, initial slip displacement, and friction stiffness based on bilinearisation from the field-measured nonlinear friction resistance force, displacement relationship using the energy method. The finite element programs, ABAQUS and EverFE, were incorporated to analyse a concrete pavement. The interlayer friction behaviour was considered both with nonlinear and bilinear models in finite element programs and the interlayer friction characteristics were modelled with connector elements. The maximum tensile stress and horizontal displacement under temperature loading conditions were calculated using analytical models and the results were compared with field data. The results of the bilinear model based on the energy method matched the field data.

“…Rasmussen & Rozycki (2001) used the same equation along with appropriate BCs to calculate the thermal-and moisture-induced slab stresses using a finite difference scheme. Xin et al (1992) also used the same equilibrium equation to approximate the structural response of continuously reinforced concrete pavement.…”

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on elasticity theory is presented to predict joint opening using a bilinear slab-subbase interfacial constraint assumption. The proposed model predicts the mean joint opening based on uniform temperature change and drying shrinkage through the slab thickness. To account for the temperature curling effect, a "correction" term to the joint opening is proposed using a closed-form solution derived from Westergaard's temperature curling deflection equation. Initial model calculation using in-situ measured pavement temperature profile suggests that proposed analytical model generates reasonable joint opening during the monitoring period.
