Mr Morolong said dry grading of roads was carried out for most of the district roads adding that many roads that use gravel course had been depleted due to continuous grading
and makes proper grading impossible.
Yas and Aragh  investigated the free vibration characteristics of rectangular continuous grading
fiber reinforced (CGFR) plates resting on elastic foundations based on the three-dimensional, linear, and small strain elasticity theory and using DQM.
Figure 3 shows the comparison using the different geometries of the complete continuous grading
of a base PG 64-22 binder to the base plus 10% 60 mesh blend.
The auction will follow the traditional format of selling better-quality stock over the first two days with continuous grading
