“…They also emphasized that slow hydration of CFA in combination with cement reduces the tendency of the layers to crack. In further research on the same mixture, the authors [21] used two nondestructive methods for the determination GRAĐEVINAR 74 (2022) 3, 189-197 Matija Zvonarić, Sanja Dimter of the dynamic modulus of elasticity: the resonant frequency method and the ultrasonic pulse velocity method. A strong relationship between these two methods was observed.…”

Considering the high price and the number of natural resources used in transport infrastructure, extending pavement lifetime is a priority for engineers. One of the most common issues in flexible pavement maintenance are reflective cracks, which reduce driving comfort and passenger safety. These cracks have two main origins, those initiated by shrinkage of the cement stabilized layer and the cracks reflected from the old pavement to a new overlay. During road maintenance, the usual remediation measure is to overlay and place a new asphalt wearing course over the old, deteriorated pavement surface. After an asphalt overlay is placed on the deteriorated pavement, the overlay can exhibit an identical crack pattern as the layer below. The main cause of reflective cracks is in the cement bound base course (CBC). Due to cement hydration, traffic load, and temperature oscillations, cracks may occur and propagate through upper layers. Much research has been conducted to prevent this problem. Some research, with an emphasis on recycled materials, is presented in this paper. The remediation measures include thin and thick interlayers and modification of the asphalt overlay characteristics.

“…Compressive strength of cement stabilizations containing recycled and waste materials Fly ash with adequate pozzolanic properties [4] and possibilities to increase strength over time can be successfully applied as a binding material in various concrete composites [12]. Fly ash has found its place in the construction of cement-stabilized pavement structures, where it can be used as a stabilizer [13].…”

This study analyses the possibilities of using up to 30% of reclaimed asphalt pavement as a substitute material for natural aggregate, along with fly ash replacing 20% or 40% of Portland cement in cement stabilizations with 4% and 6% of binder. The Proctor test was used to determine maximum dry density and optimal moisture content of cement-based stabilizations. The compressive strength was tested after 7, 28, and 90 days. Parameters influencing 28-day compressive strength were evaluated by full factorial design and by classification in strength classes. The results obtained justify the utilisation of waste and recycled materials in pavement structures.

“…Although this is most likely a reasonable assumption, there is not sufficient information available in literature for this relationship to be well-established. In fact, studies available in literature involving the determination of dynamic Poisson's ratio or shear moduli, such as [19] and [20], have only focused on very specific types of constituents. Moreover, although Totoev and Nichols [15,16] mention that UPV measurements can provide information on the isotropy of bricks, no detailed information is provided on the validity or correct interpretation of P-wave travel time readings for anisotropic cases.…”

When subjected to dynamic loading, materials can exhibit a mechanical behaviour quite different from its static counterpart. The evaluation of dynamic properties is thus very useful in the assessment of existing masonry structures. This paper presents results of an experimental campaign to determine both the dynamic Young's modulus and the shear modulus of brick masonry constituents through two non-destructive testing methods. Following a discussion on the reliability of the methods, a robust procedure is described and tested on a variety of samples. The results show that the techniques can be successfully applied to provide reliable estimates of the dynamic elastic properties of brick masonry constituents.
