“…Furthermore, a study was conducted to evaluate the cracking resistance of semi-flexible pavement incorporating modified asphalt with Styrene-Butadiene-Styrene, Modified Agent-10 (MA agent) and fibers. The results indicated that the addition of these modifiers reduces the strength, but improves the fatigue (cracking) resistance of semi-flexible pavements [18]. In another study it was concluded that latex modified cement grout for grouted macadam showed significant improvement against rutting, moisture damage, low temperature performance and improved flexural strength, while only slightly compromising on fluidity [19].…”

In this study the effect of irradiated and non-irradiated waste polyethylene terephthalate (PET) as replacement of cement and fly-ash in ordinary Portland cement (OPC) and geopolymeric cement (GPC) based cementitious grouts on flexural strength of semi-flexible pavement specimens were evaluated. The porous asphalt gradation was selected based on Malaysian specifications for semi-flexible pavements with a target of 30% air voids. The cement content in the OPC grouts and the fly-ash content in the GPC based grouts were partially replaced with 1.25% PET (using both irradiated and non-irradiated PET). Beam specimens were prepared and tested for flexural strength properties using center point loading configuration. The grouts modified with recycled waste plastic (PET) showed approximately the same results as obtained from the control specimens. Although the replacement amount was low (1.25% by weight of cement), nonetheless, significant impact on reducing CO2 emissions is expected when preparing grouts for mass construction of semi-flexible pavement surfaces. Similarly, effective recycling of waste plastics in road construction and replacing OPC with plastic and geopolymers will have a positive effect on the environment and will furthermore contribute to sustainable pavement construction.

“…Moreover, SFPS provides superior resistance to rutting and are not susceptible to permanent deformation [18]. Semi-flexible pavements have been constructed in various countries as a highway intersection, bus lanes in urban areas, tunnels roads, the pavement in industrial area for the movement of heavy machinery, airport taxiways and aprons as fuel and spillage resistance [15,16,[21][22][23][24][25][26][27].…”

This chapter describes a review of the design and formulation of various cementitious grouts for semi-flexible pavement surfaces. Additionally, the authors also conducted extensive experimental work on the possibility of using a most effective and innovative way of recycling waste polyethylene terephthalate (PET) by exposing to gamma radiation and using as a replacement of Ordinary portland cement in the formulation of cement grouts for semi-flexible pavement surfaces. In the current study, cement in the grouts was replaced with PET (regular and irradiated), fly ash and silica fume and was evaluated for flowability and strength properties. The study concludes that normal PET causes a significant reduction in compressive strength, however, some of the strength is restored when irradiated PET was used. The recycling of waste PET, as a cement replacement in the cementitious grouts for semi-flexible pavement surfaces, with the irradiation process can be doubled as compared to utilizing normal/regular PET.

“…Semi-flexible pavement coating material (SFPCM), with the advantage of the flexibility of asphalt concrete pavement and the rigidity of cement concrete pavement materials, is a new kind of composite pavement material, which is made by pouring special cement mortar into the open porous asphalt mixture (void ratio is 20%~28%) [1]. The asphalt concrete pavement forms the material strength through aggregate interlocking [2,3], but the SFPCM forms the material strength through mutual intercalation of aggregate and cement stone, which improves the ability of pavement to resist the load [4,5]. In addition, its high temperature stability and water damage resistance are superior to asphalt concrete pavement, and its shear resistance, fatigue resistance, and slip resistance are also superior to cement concrete pavement.…”

This paper aims to optimize the asphalt-mortar interface characteristics of semi-flexible pavement coating material (SFPCM), three types of the interface modifiers, namely the silane coupling agent, carboxylated styrene-butadiene latex, and cationic emulsified asphalt, are selected to add into the cement mortar to optimize the asphalt-mortar interface. The microscopic characteristics of the asphalt-mortar interface and the macroscopic pavement performance of the SFPCM after the interface optimization are investigated to reveal the effect of interface modifiers and determine the best formula. Results show that: (1) The dry shrinkage of the cement mortar is increased with the increased dosage of the interface modifiers, while the strength is decreased accordingly; (2) the optimum dosages of the silane coupling agent, carboxylated styrene butadiene latex, and cationic emulsified asphalt are 0.5%, 10%, and 5%, respectively; (3) the microscopic asphalt-mortar interface characteristics of the SFPCM with different interface modifiers have significant differences; (4) the SFPCM with the cationic emulsified asphalt presents the best pavement performance, particularly the high-temperature stability. These results can be attributed to improve the pavement properties of SFPCM.
