Background technique

In order to ensure the construction and workability of cement-stabilized porous basalt gravel during construction, it is necessary to strictly control the moisture content and cement dosage, and arrange the transportation distance reasonably. Due to the characteristics of basalt gravel with more pores and high water absorption, the workability of cement-stabilized porous basalt gravel decreases significantly from mixing to transportation to the construction site, and it is difficult for transportation vehicles to unload during construction. Existing test and detection instruments cannot simulate the difficulty of unloading of actual transportation vehicles. Therefore, a cement-stabilized porous basalt gravel construction and workability test device was developed to simulate the difficulty of unloading of actual transportation vehicles, so as to ensure the construction and workability of cement-stabilized porous basalt gravel at the construction site.
