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.

Assessing and Improving the Performance of Grouted Macadam
American Journal of Engineering and Applied Sciences, 2020 There are many road defects appear in flexible pavement layers. Rutting, raveling and cracks are considered the main problems in Egypt. Using grouted macadam system as a surface asphaltic layer (or called Semi-Flexible Pavement (SFP)) has many advantages such as saving the natural asphalt and enhancing the performance against deteriorations.

Laboratory Characterization of a Cement Grouted Bituminous Macadam Made With Portland Slag Cement
International Journal of Pavement Research and Technology, 2019 Cement grouted bituminous macadam (CGBM) consists of porous asphalt skeleton with a void content of 25% to 35%, which is filled with a cementitious grout. It is usually considered as a semi-flexible layer as it incorporates both the flexibility of bituminous layer and the stiffness of the grout content. In this study, a porous asphalt skeleton with 28%

Semi-Flexible Pavement: A Review of Design and Performance Evaluation [PDF]
E3S Web of Conferences, 2023 It is known to researchers in the field of road construction and development. Three types of pavement are rigid, flexible, and composite paving. The composite pavement consists of a layer of flexible pavement on top of which a layer of rigid pavement is ...

Backcalculation of pavements incorporating Grouted Macadam technology
Road Materials and Pavement Design, 2017 Applying cement grout with a high compressive strength to a porous layer made of asphalt concrete results in a pavement with the properties of an intermediate type that combines the characteristics of both flexible and rigid pavements. This solution is known as Grouted Macadam (GM).

A simple approach to the design of pavements incorporating grouted macadams
, 2007 Grouted macadams form a semi-flexible class of composites whose behaviour lies somewhere between concrete and conventional asphalt materials, having both excellent rut resistance and a degree of flexibility. This paper presents a series of pavement design computer simulations, based on results obtained from laboratory fatigue and stiffness tests on ...
