Performance Analysis of Cold-Mixed Integrated Semi-Flexible Pavement Mixtures [PDF]
MaterialsTo address the issues of high energy consumption and unstable construction quality caused by high-temperature heating during the preparation of traditional hot-mixed/grouted semi-flexible pavement (SFP) mixtures, a cold-mixed integrated (CMI) process was proposed. In addition, the material composition of the mixtures was optimized.

Laboratory and field investigation of grouted macadam for semi-flexible pavements
Case Studies in Construction Materials, 2022 Grouted macadam (GM) made of an open-graded asphalt skeleton whose air voids are filled with a cementitious grout, is used as wearing course in semi-flexible pavements.

Asessing the Compressive Strength Properties of Semi-Flexible Pavements
Procedia Engineering, 2013 AbstractSemi-flexible pavements are manufactured by producing a very open porous asphalt skeleton and filling the voids with selected cementitious grouts. The resultant composites, referred to as “grouted macadams”, combine the flexibility of the bituminous component with the strength and rigidity of the cementitious component.

Exploring the potential applications of semi-flexible pavement: A comprehensive review
Reviews on Advanced Materials ScienceA 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

Early life field performance of innovative sustainable semi-flexible pavements
International Conference on Road and Rail InfrastructureSemi-flexible pavements in heavy loads areas are recommended to guarantee good performance and safety. They are usually constructed by placing a wearing layer of grouted macadam, a composite material consisting of a porous Hot Mix Asphalt (HMA) skeleton grouted with a cementitious matrix.

Mechanistic modelling of weak interlayers in flexible and semi-flexible road pavements: Part 2
Journal of the South African Institution of Civil Engineers, 2012 This paper (Part 2 of a two-part set of papers) discusses models and illustrates the adverse effects of weak layers, interlayers, laminations and/or weak interfaces in flexible and semi-flexible pavements, also incorporating lightly cemented layers.

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.

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
