“…The following results from tests for the flow cone, compressive strength, and flexural strength of fresh and hard grout are displayed: 3 and Figure 8 show the flow time that was test used to evaluate the performance of the grout. According to previous studies, a flow cone test is conducted for several types of grouts to achieve a sufficient fluidity of (11-16) seconds [5,12] for appropriate grout injection into the SFP surface mixture. The presence of a superplasticizer has a substantial impact on the workability of cementitious slurries, regardless of the W/B ratio.…”

“…Superplasticizers based on carboxylic acids or polymers are more effective at countering the fluidity introduced by the sulphonated naphthalene formulation, which depresses the cementitious particle. The amount of water in the grout has a significant impact not only on its fluidity but also on its strength [11] To test the fluidity of the grout, the flow cone method is commonly used; according to this method and previous researchers, the flow time should be between 11 and 16 seconds [12] Due to the high fluidity of the grouting material, flow times greater than 16 seconds may result in more voids in the SFP combination not being filled, whereas flow times less than 11 seconds may result in the impossibility of penetrating the grout material to voids in SFP mixture. In particular, the superplasticizer is one of the material types that is highly successful in enhancing grout fluidity.…”

Cement-based grouts are described as a liquid mixture with higher flowability that contains cement, additives, water, and a superplasticizer. Cement-based grouts can be utilized to fill minor voids and gaps in addition to repairing cracks in earthen structures to restore structural continuity. In most cases, structural grouting is used in conjunction with other strengthening methods like adding tie-rods or reinforcing meshes. Grout is usually used with semi-flexible pavement (SFP). SFP is a new pavement technology comprised of open-graded asphalt concrete with a high air void content that is filled by injecting special grouting materials. The goal of this research is to figure out what happens to the mechanical properties of grout when a proposed by-product is used as a supplement to cementitious materials. The specified grouts were made from cement, water, ceramic waste powder (CWP), and superplasticizer (SP). Scanning electron microscopy (SEM) and energy-dispersive x-ray (EDX) analysis were used to characterize the physical and chemical properties of the waste material after it had been crushed and finely ground. The pozzolanic behaviour of the material was evaluated by substituting ceramic waste for Portland cement at varying percentages (from 15% to 50%), and the modified grout was characterized through a variety of tests that included flow cone testing, as well as compression and flexural strength tests Based on the results of these tests, the best amount of CWP to use as a replacement for cement in terms of its mechanical properties is 20%.

“…The use of polymers to enhance the performance of asphalt binders and thereby improve asphalt pavement quality is a popular direction for current research [6][7][8]. For instance, the styrene-butadiene-styrene (SBS) block copolymer, with its strength and elasticity that are derived from a three-dimensional network of crosslinked molecules, has shown significant potential.…”

“…(5) The high viscosity and adhesive properties of PF-modified asphalt reduce porosity within the mixture, enhancing adhesion between different components and improving resistance to high-temperature deformation as well as stripping in the mixture. (6) The uniform dispersion of PF particles without aggregation contributes to limiting the asphalt flow at high temperatures and inhibiting oxygen penetration.…”

This study comprehensively examines the influence of phenol-formaldehyde resin (PF) on the performance of base asphalt and its mixtures for road applications, emphasizing its innovative use in enhancing pavement quality. Optimal PF content was determined through the evaluation of standard indicators and rotational viscosity. In-depth analyses of PF-modified asphalt’s high- and low-temperature rheological properties and viscoelastic behavior were conducted using dynamic shear rheometers and bending beam rheometers. Aging resistance was assessed through short-term aging and performance grade (PG) grading. Moreover, Marshall and water stability tests were performed on PF-modified asphalt mixtures. Findings indicate that the uniform dispersion of PF particles effectively inhibits asphalt flow at high temperatures, impedes oxygen penetration, and delays the transition from elasticity to viscosity. These unique properties enhance the high-temperature stability, rutting resistance, and aging resistance of PF-modified asphalt. However, under extremely low temperatures, PF’s brittleness may impact asphalt flexibility. Nonetheless, the structural advantages of PF-modified asphalt, such as improved mixture density and stability, contribute to enhanced high-temperature performance, water stability, adhesion, and freeze–thaw cycle stability. This research demonstrates the feasibility and effectiveness of using PF to enhance the overall performance of base asphalt and asphalt mixtures for road construction.

“…But the recent trend of more heavy traffic and bad environmental conditions has made it more likely to have problems like fatigue, cracks, ruts, and low-temperature cracking. Most damage to flexible pavement comes from fatigue and rutting [3][4]. These may have an impact on both its performance and useful life.…”

In last years, a new type of pavement has gained popularity, this type is called Semi-Flexible Pavement (SFP). It consists of porous asphalt with high air voids between (25-35) % filled with cementitious grout materials. This type of pavement substance offers substantial advantages over both common types of pavements (concrete and flexible) such as good resistance to rutting and durability. SFP is considered an alternative pavement to exceed the drawbacks that occur for both flexible and concrete pavements. SFP has good features against permanent deformation, oil spillage, and fatigue resistance. Previous studies have shown that it can be used in a variety of applications such as highways, motorways, bridge deck pavement, tunnels, industrial areas with industrial equipment traffic, airport aprons, and stations. The goal of this research is to identify and compile the most significant research papers using the Web of Science (WOS), analyze the data using the VOS viewer software, as well as learn which countries and institutions had published the most articles relating to the subject of cementitious grout material as it relates to semi-flexible. It was also done to learn more about the authors and their collaboration. In addition to knowing the keywords that will aid researchers in their research on this topic, using these studies to better understand the elements that affect how well semi-flexible mixtures and grouts perform such as porous asphalt Mixture gradation and grout material components.
