Backcalculation of pavements incorporating Grouted Macadam technology [PDF]
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).

The effect of using rest periods in 4PB tests on the fatigue life of grouted macadams [PDF]
, 2009 Four-point bending tests are commonly used to assess the fatigue resistance of bi-tuminous bound materials that are used in road pavements. However, it is difficult to establish a reliable relationship between the laboratory test results and the field performance of the mate-rial.

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.
