Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures

Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

Onsite Use of Recycled Asphalt Pavement Materials and Geocells to Reconstruct Pavements Damaged by Heavy Trucks

Sensitivity Analysis of Principal Stresses in Concrete Slab of Rigid Pavement Made From Recycled Materials

Complex sensitivity analysis of stresses in a concrete slab of the real type of rigid pavement made from recycled materials is performed. The computational model of the pavement is designed as a spatial (3D) model, is based on a nonlinear variant of the finite element method that respects the structural nonlinearity, enables to model different arrangements of joints, and the entire model can be...

Decalcification shrinkage of cement paste

Decalcification of cement paste in concrete is associated with several modes of chemical degradation including leaching, carbonation and sulfate attack. The primary aim of the current study was to investigate the effects of decalcification under saturated conditions on the dimensional stability of cement paste. Thin (0.8 mm) specimens of tricalcium silicate (C3S) paste, white portland cement (W...
