“…The ASTM gradations depict the highest ITS value of about 1.6 MPa at 4.5 bitumen content, followed by New Jersey with an ITS value of about 1.4 MPa. The lowest ITS value was obtained for New Zealand, with about 1.35 MPa [ 107 ]. However, no data are available related to air voids obtained for these selected gradations.…”

“…Gradation type, bitumen content, and curing age also significantly influence the compressive and flexural strength of semi-flexible mixtures. Sunil, 2020 [ 107 ] uses ASTM, New Jersey, and New Zealand-based porous asphalt gradation to produce semi-flexible mixtures. Bitumen content of 4%, 4.5%, and 5% by weight of aggregates was used to prepare porous asphalt mixtures for all three gradations.…”

“…Similarly, the gradations adopted from ASTM showed higher compressive and flexural strength at all bitumen contents and curing ages, followed by the New Jersey gradation. Moreover, all the mixtures’ compressive and flexural strengths significantly increased with increasing curing age, from 1 day to 28 days [ 107 ].…”

“…Optimum compositions of cement grouts with a cement:sand ratio of 1:1, w/c ratio of 0.45, and superplasticizer dose of 0.4% were used for all mixture combinations. The semi-flexible mixtures with ASTM gradations showed the highest fatigue life at different stress ratios (10, 20, and 30%) compared with New Jersey and New Zealand gradations [ 107 ].…”

“…A study concluded that a semi-flexible mixture with New Zealand and ASTM gradation at 4.5% bitumen content showed quite similar deformation results and completed 20,000 cycles without failure and negligible deformation was witnessed [ 107 ]. Similarly, semi-flexible mixtures produced from different grouts exhibit the smallest rut depth and the highest dynamic stability of more than 13,000 times/mm at 60 °C temperature [ 101 ].…”

Cementitious Grouts for Semi-Flexible Pavement Surfaces—A Review

The hybrid type of pavement called semi-flexible or grouted macadam has gained popularity over the last few decades in various countries, as it provides significant advantages over both rigid and conventional flexible pavements. The semi-flexible pavement surface consists of an open-graded asphalt mixture with high percentage voids into which flowable cementitious slurry is allowed to penetrate due to gravitational effect. Several researchers have conducted laboratory, as well as field, experiments on evaluating the performance of semi-flexible layers using different compositions of cementitious grouts. The composition of grouts (i.e., water/cement ratio, superplasticizer, polymers, admixtures, and other supplementary materials) has a significant effect on the performance of grouts and semi-flexible mixtures. A comprehensive review of cementitious grouts and their effect on the performance of semi-flexible layers are presented and summarized in this review study. The effect of byproducts and other admixtures/additives on the mechanical properties of grouts are also discussed. Finally, recommendations on the composition of cementitious grouts have been suggested.

Fatigue Prediction Model and Stiffness Modulus for Semi-Flexible Pavement Surfacing Using Irradiated Waste Polyethylene Terephthalate-Based Cement Grouts

et al. 2022

View full text Add to dashboard Cite

Semi-flexible pavement surfacing, or grouted macadam, is an alternative to conventional flexible and rigid pavement. It is constructed by injecting cementitious grout into the voids of an open-graded asphalt surfacing. The cement used in cementitious grouts has adverse environmental effects because of the carbon dioxide emission in cement production. The objective of this study was to investigate the potential of using irradiated waste polyethylene terephthalate (PET) and fly ash (FA) as a (partial) cement replacement in cementitious grouts for semi-flexible pavement surfacing. This study sought to assess the stiffness modulus and fatigue properties of the semi-flexible specimens prepared with control grout, regular PET (2.57% PET + 10% FA) and irradiated PET (4.75% PET + 10% FA)-based grouts and compares the stiffness modulus and fatigue properties of semi-flexible specimens with the conventional hot mix asphalt (HMA) concrete. The semi-flexible surfacing specimens showed superior performance, higher stiffness modulus, and better fatigue life than the hot mix asphalt. The difference in fatigue cycles was apparent at lower stress ratios of 25 and 30%. The semi-flexible pavement mixtures exceeded 100,000 cycles at the lowest stress ratio of 25%, while the HMA fatigue cycles were less than 100,000 cycles. Furthermore, the semi-flexible specimen with irradiated PET (which contain a higher amount of waste PET than the regular PET) showed similar stiffness modulus and fatigue life as the specimens with regular PET and control grout. The irradiation technique offers a sustainable solution for recycling higher amounts of waste PET in highway materials for semi-flexible pavement surfacing.
