Strength and Durability of Hybrid Fiber-Reinforced Latex-Modified Rapid-Set Cement Preplaced Concrete for Emergency Concrete Pavement Repair

The benefits of using reinforcing fibers in latex-modified rapid-set cement preplaced concrete for emergency pavement repairs were examined terms strength, permeability, and durability as functions the type fiber. Single-type fibers, including jute, poly (vinyl alcohol) (PVA), nylon well hybrid fiber mixtures prepared with two aforementioned at a 1:1 weight ratio, evaluated. Fibers incorporated into mixture 1.2 kg/m3. A vibratory press compactor that simulates roller compaction was used to increase densification resulting repair material. fiber-reinforced (HFLMC) manufactured satisfy criteria opening traffic, i.e., compressive strength 21 MPa or higher, flexural 3.5 higher after 4 h. Pavement requiring removed replaced coarse aggregate. binder, latex then mixed placed onto aggregate layer. considered complete compaction. HFLMC satisfied all test criteria. Furthermore, concretes made more mechanically sound than those single variety. Hybrid PVA exhibited best properties repair. These results indicate is suitable
