Characterization of Cement Grouted Semi-flexible Pavement
2021This study over semi-flexible pavement (SFP) has been characterized in various stages. The first stage is about the gradation of aggregate for which six trials were made with the course and fine aggregate with three replicates to achieve void ratio between 30 and 70%.

Utilization of Waste Rubber Powder in Semi-Flexible Pavement
Key Engineering Materials, 2014The central concept of semi-flexible pavement (SFP) is to combine the best qualities of concrete and asphalt pavement by means of filling the voids of the large gap asphalt mixture (LGAM) with good fluidity grout. The major purpose of this study is to determine the feasibility of utilizing waste rubber powder in the grout so as to reduce the stiffness ...

A state of the art of semi-flexible pavements: Introduction, design, and performance
Construction and Building Materials, 2020Abstract Semi-flexible pavement (SFP) is a new pavement technology consisting of open-graded asphalt concrete with a high air void content filled by injecting special grouting materials. The SFP is constructed without expansion, contraction, and construction joints and also demonstrates prominent rutting and shoving/corrugation resistances. These new

Influences of matrix asphalt on performance of irrigated semi-flexible pavement
AIP Conference Proceedings, 2019In order to find out the suitable asphalt types and corresponding voidage of the Irrigated semi-flexible pavement(ISFP), SBS modified asphalt and 70# road petroleum asphalt were used to form the matrix asphalt mixture with voidage of 10%, 15%, 20%, 25%, 30%, 35%.

Development of a sustainable semi-flexible pavement composite containing recycled asphalt pavement
The purpose of this research is to investigate the feasibility of Recycled Asphalt Pavement (RAP) material in developing sustainable Semi-Flexible Pavement (SFP) composite material. While a lot of effort has been made in the last several years to explore the potential of RAP in bituminous and cement concrete pavement, such an attempt has not been made ...Sharma, Sawarmal +4 more
