Exploring the potential applications of semi-flexible pavement: A comprehensive review

Reviews on Advanced Materials Science
A semi-flexible pavement (SFP) is formed from two materials of different characteristics, including a porous asphalt mixture (PAM) with flexible properties and hardened cement with rigid properties. Grouting materials and PAM’s porosity play an essential

EVALUATION OF SEMI-FLEXIBLE PAVEMENT PERFORMANCE [PDF]

Journal of Al-Azhar University Engineering Sector, 2020
This study aims at characterization and design new special type of asphalt mixture havinglower asphalt content and higher rutting resistance to be used in paving surface layers atheavy loads areas. To achieve this objective, grouting technique of permeable open gradedasphalt mixtures was used. Such type of pavement is called as a semi-flexible pavement

Experimental Study and Performance Characterization of Semi-Flexible Pavements [PDF]

Coatings, 2022
Semi-flexible pavement (SFP) is made up of a porous skeleton of asphalt mixture and cement grout. This special structure granted SFP superior strength and durability and made it a promising solution for the paving of heavy trafficked area. This paper performed in-depth study on the mechanistic behavior of SFP.

Durability Evaluation: Sustainable Semi-flexible Pavement Mixtures

IOP Conference Series: Materials Science and Engineering, 2021
Abstract The modern paving industry requires the production of high-performance pavement using more sustainable approaches. Semi-flexible pavement (SFP), prepared by filling an open-graded asphalt skeleton with cement-based grouting material, has been shown to offer high performance for heavily loaded highway and airport pavement ...

Characterizing polymer modified Cementations grout for semi-flexible pavement mixtures

Al-Qadisiyah Journal for Engineering Sciences, 2021
In general, injecting grouts into small fractures, cavities, porous soil media, areas of water leakage, fixing cracks or defects in concrete, and filling spaces beneath metal bases or digging anchors are widely applied because of the great strength and workability of the cement in these materials.
